PlotJuggler 3.3

PlotJuggler is a tool to visualize time series that is fast, powerful and intuitive.

Noteworthy features:

  • Simple Drag & Drop user interface.
  • Load data from file.
  • Connect to live streaming of data.
  • Save the visualization layout and configurations to re-use them later.
  • Fast OpenGL visualization.
  • Can handle thousands of timeseries and millions of data points.
  • Transform your data using a simple editor: derivative, moving average, integral, etc…
  • PlotJuggler can be easily extended using plugins.


Data sources (file and streaming)

  • Load CSV files.
  • Load ULog (PX4).
  • Subscribe to many different streaming sources: MQTT, Websockets, ZeroMQ, UDP, etc.
  • Understands data formats such as JSON, CBOR, BSON, Message Pack, etc.
  • Well integrated with ROS: open rosbags and/or subscribe to ROS topics (both ROS1 and ROS2).
  • Supports the Lab Streaming Layer, that is used by many devices.
  • Easily add your custom data source and/or formats...

Transform and analyze your data

PlotJuggler makes it easy to visualize data but also to analyze it. You can manipulate your time series using a simple and extendable Transform Editor.

Alternatively, you may use the Custom Function Editor, that allows you to create Multi-input / Single-output functions using a scripting language based on Lua.

If you are not familiar with Lua, don't be afraid, you won't need more than 5 minutes to learn it ;)


To learns how to use PlotJuggler, check the tutorials here:

Tutorial 1 Tutorial 2 Tutorial 3

Supported plugins

Some plugin can be found in a different repository. The individual README files should include all the information needed to compile and use the plugin.

Please submit specific issues, Pull Requests and questions on the related Github repository:

If you want a simple example to learn how to write your own plugins, have a look at PlotJuggler/plotjuggler-sample-plugins


Binary installers (with basic plugins)

Linux AppImage (compatible with Ubuntu 18.04 or later: PlotJuggler-3.2.0-x86_64.AppImage

Windows Installer: PlotJuggler-Windows-3.1.1-installer

For ROS User

Install the debian packages using:

 sudo apt install ros-<distro>-plotjuggler-ros

Alternatively, you may download the Snaps version that include the ROS1 plugins:

Get it from the Snap Store

How to build

Clone the repository as usual:

git clone

The only binary dependency that you need installed in your system is Qt5. On Ubuntu, the debians can be installed with the the command:

sudo apt -y install qtbase5-dev libqt5svg5-dev libqt5websockets5-dev libqt5opengl5-dev libqt5x11extras5-dev libprotoc-dev

On Fedora:

sudo dnf install qt5-qtbase-devel qt5-qtsvg-devel qt5-websockets-devel qt5-qtopendl-devel qt5-qtx11extras-devel

Then compile using cmake (qmake is NOT supported):

 mkdir build; cd build
 cmake ..
 sudo make install

Note: the plugins need to be installed in the same folder of the executable.

Note for ROS users

To install PlotJuggler, just type:

sudo apt install ros-${ROS_DISTRO}-plotjuggler-ros

To launch PlotJuggler on ROS, use the command:

  rosrun plotjuggler plotjuggler

or, if are using ROS2:

   ros2 run plotjuggler plotjuggler

Since version 3.x, ROS plugins have been moved to a separate repository:

Refer to the instructions in the this repository if you want to compile PJ and its ROS plugins from source.

If you like PlotJuggler, support it.

PlotJuggler required a lot of work to be developed; my goal is to build the most intuitive and powerfull tool to visualize data and timeseries.

If you find PlotJuggler useful, consider making a donation on PayPal or become a Github Sponsor.

If you use PlotJuggler at work, your company can support the development of those specific features they need.

Contact me for more details.

    New License


    as you probably noticed, I decided to switch to MPL-2.,0 license, instead of LGPL.

    My main goal here is to make it easier for some users to create proprietary plugins. They will need to link statically to the plotjuggler_base library and the LGPL make that ... complicated.

    I am asking you if you agree (please answer in this thread), because you contributed in the past with PRs. I think that having your permission is mandatory, for legal reasons.

  • Crash when loading layout file

    Crash when loading layout file

    Thanks for contributing to PlotJuggler. You are great!

    Problem description

    I save a layout file that has a Custom Series called Power (save custom transformations option is selected. It multiplies current and voltage. I then close plotjuggler and reopen it, and load the layout file. It crashes in lua_rawgeti.

    I've attached the layout file.

    This is using main. The crash does not happen on 3.2.

    Steps to reproduce (important)

    See description

    • Describe your platform / Operative System. I'm using MacOS Big Sur. I know MacOS isn't supported. Submitting this in case it happens on other platforms as well.

    • Check if the problem can be reproduced using the dummy data created by the command line argument "-t" or one of the files in the folder "datasamples".

    • If it can't be reproduced with the dummy data, please share the CSV file or the rosbag that can be used to reproduce the problem.

  • Can PlotJuggler help with plotting data indexed from multiple clocks?

    Can PlotJuggler help with plotting data indexed from multiple clocks?

    I have data indexed with multiple time samples from 3 separate clocks across 3 separate devices, and I'm trying to visualize the time differences and errors, I've included my specific questions and details below.

    1. Do you think plotjuggler is the right tool for such a use case?
    2. Which of the following would be easiest step to view my data? It is currently logged to disk in a flatbuffers message (like a rosmsg or protobuf). Options include:
      1. dump the data into a rosbag
      2. dump to CSV (must every csv entry be occupied or can some be blank?)
      3. write a custom plugin
      4. another alternative you might advise (is there a way to load json?)

    The key data channels will be:

    • A 3D camera's clock time
      • 6DOF poses of objects the camera can see
    • A robot arm's clock time
      • 7DOF joint angles, and possibly torque
      • 6DOF end effector pose estimate
    • The computer clock time immediately before and after receiving the above two times.

    The actual message data type LogKUKAiiwaFusionTrack.fbs is simply a vector of time stamped messages, which contain other data channels:

    union DeviceState {KUKAiiwaState, FusionTrackMessage}
    // a log file is a series of GRLMessage entities
    // The TimeEvent should contain the necessary data,
    // and only ONE of kukaiiwa or fusionTrack should
    // be filled out for each message.
    table KUKAiiwaFusionTrackMessage {
        // an easy to use ros compatible timestamp
        // a more detailed timestamp based on google cartographer
        // and the triggersync paper
    table LogKUKAiiwaFusionTrack {

    Here is the time data I record for each device:

    /// Note that all of these time entries are
    /// longs with a minimum step of 100ns,
    /// see google cartographer's cartographer::common::time
    table TimeEvent {
      /// Identifying string for this time stamped data topic
      /// something like "/opticaltracker/00000000/frame" where
      /// 00000000 is the serial number of the optical tracker.
      /// The time just before a data update request is made
      /// Identifying string for the clock used to drive the device
      /// something like "/opticaltracker/00000000/clock"
      /// if it is the clock internal to a sensor like an optical tracker
      /// The time provided by the device specified by device_clock_id
      /// Identifying string for the clock used to drive the device
      /// or "/control_computer/clock/steady" if the device has no clock
      /// and the time is the desktop computer
      /// running the steady clock (vs clocks which might change time)
      /// The time at which the data was received
      /// The corrected local time which represents when the sensor
      /// data was actually captured.
      /// Estimated duration of the skew between the device clock
      /// and the local time clock
      /// The minimum expected delay in transporting the data request

    This is based on the rosmsg Event.msg, from a paper called triggersync as follows (there is a TimeStamped version as well):

    string  event_name
    time    local_request_time
    string  device_clock_id
    time    device_time
    string  local_clock_id
    time    local_receive_time
    time    corrected_local_time
    float64 clock_skew
    duration    min_transport_delay

    I would appreciate your patience and recommendation, I know this is a very detailed question. Others in my lab use plotjuggler and it is highly regarded, so I'm seeing if I can use it too. Thanks!

  • Feature request: equal axis scaling

    Feature request: equal axis scaling

    Dear Davide,

    Here comes another feature request: When using a custom x-axis (dragged with the right mouse button), I can create an x,y position plot which is very nice. However, it would be very useful to have an option for a locked axis ratio such that, e.g. right angles, appear as such in the plot. Like with the Matlab command "axis equal".

    Best regards

  • Custom calculations

    Custom calculations

    Hi, Thanks for this great program !

    This PR adds custom calculations / transforms on plots. To open the dialog you can right click on a curve in the left listWidget, then select the "create math plot" option in the context menu. Example ( where i extract the yaw euler angle from the 4 quaternion values ) : quaternion_to_euler

    Any javascript expression can be used for the calculations.

    Another example (1st order IIR low pass filter) : add_low_pass1 add_low_pass2

    Some remarks :

    Why javascript ? Using some compiled scripting language like cling or lua would have been nicer, but Qt has native support for javascript (using QJSEngine). This makes the building and deploying a lot easier (I only added two words in the main CMakeList.txt).

    XY plot To make the right-click context menu on the FilterableListWidget work, I had to change the way to assign a plot to the X axis. Instead of pressing right click and drag-and-drop, you just have to left-click drag the plot on the X axis. I hope this change doesn't mind you !

    Streaming For the moment the calculations aren't refreshed during streaming, but in the context menu you can manually force a refresh of the expression.

    Sorry for the big commit, this change was a little bit more complicated than expected !

  • Quits on Layout Load

    Quits on Layout Load

    Every time I load a layout PJ quits (and for good measure I made a layout based on building the Main branch [as of today[).

    If I open PJ without loading a layout, it works for awhile and then on doing some specific transformations causes it to crash (non-specific, differs each time).

    Heres the kicker - this is on a Mac but im seeing similar (not exact) issues on Ubuntu. The similar being that specific transformations cause it to crash but not so much the quit on layout load (I know... two specific issues).

    I gather this will be difficult to diagnose (given not officially supported on Mac) but willing to help however needed - something in the libraries when on a Mac.

  • XY curve axis scaling issue when there is a large difference between X and Y values

    XY curve axis scaling issue when there is a large difference between X and Y values

    When loading XY data where there's a large difference between the X and Y values (in the example below two orders of magnitude), the scaling for the other axis becomes unusable (not properly scaled) and unresponsive


    The issue persists after drawing a zoom rectangle, and it is only after the zoom area's X range is sufficiently small that the Y axis scales correctly

  • Different values in Plotjuggler and RQT

    Different values in Plotjuggler and RQT

    Thanks for contributing to PlotJuggler. You are great!

    Problem description

    We are implementing a UDP ROS2 bridge as hardware driver and want to evaluate if the informations are parsed correctly. But for some unknown reason, the values of the parsed ROS message are different, depending on where you analyse them. By looking in terminal with ros2 topic echo $TOPIC the values are correct, also when visualizing it with RQT plot (see screenshot). But when using Plotjuggler, the values are mixed in the message attributes. For example plotjuggler shows the information of the attribute "status_count" in "kf_steady_state". It doesnt matter of its on live data or with a recorded rosbag.

    Bildschirmfoto vom 2022-12-06 11-52-02 Correct values in RQT

    Bildschirmfoto vom 2022-12-06 11-52-41 Plot of the same topic as RQT, but Plotjuggler shows wrong values of it. Instead you can see left in topic-view that the information is in "steady_state"

    This bug was found with the following setup:

    • Ubuntu 20.04 / ROS2 Galactic
    • Ubuntu 22.04 / ROS2 Humble Here would be a short rosbag to reproduce the described behavior. The invalid values are in the /genesys/adma/data_scaled(status) topic.

  • Add CodeQL workflow

    Add CodeQL workflow

    Hi facontidavide/PlotJuggler!

    This is not an automatic, 🤖-generated PR, as you can check in my GitHub profile, I work for GitHub and I am part of the GitHub Security Lab which is helping out with the migration of LGTM configurations to Code Scanning. You might have heard that we've integrated LGTM's underlying CodeQL analysis engine natively into GitHub. The result is GitHub code scanning!

    With LGTM fully integrated into code scanning, we are focused on improving CodeQL within the native GitHub code scanning experience. In order to take advantage of current and future improvements to our analysis capabilities, we suggest you enable code scanning on your repository. Please take a look at our blog post for more information.

    This pull request enables code scanning by adding an auto-generated codeql.yml workflow file for GitHub Actions to your repository — take a look! We tested it before opening this pull request, so all should be working :heavy_check_mark:. In fact, you might already have seen some alerts appear on this pull request!

    Where needed and if possible, we’ve adjusted the configuration to the needs of your particular repository. But of course, you should feel free to tweak it further! Check this page for detailed documentation.

    Questions? Check out the FAQ below!


    Click here to expand the FAQ section

    How often will the code scanning analysis run?

    By default, code scanning will trigger a scan with the CodeQL engine on the following events:

    • On every pull request — to flag up potential security problems for you to investigate before merging a PR.
    • On every push to your default branch and other protected branches — this keeps the analysis results on your repository’s Security tab up to date.
    • Once a week at a fixed time — to make sure you benefit from the latest updated security analysis even when no code was committed or PRs were opened.

    What will this cost?

    Nothing! The CodeQL engine will run inside GitHub Actions, making use of your unlimited free compute minutes for public repositories.

    What types of problems does CodeQL find?

    The CodeQL engine that powers GitHub code scanning is the exact same engine that powers The exact set of rules has been tweaked slightly, but you should see almost exactly the same types of alerts as you were used to on we’ve enabled the security-and-quality query suite for you.

    How do I upgrade my CodeQL engine?

    No need! New versions of the CodeQL analysis are constantly deployed on; your repository will automatically benefit from the most recently released version.

    The analysis doesn’t seem to be working

    If you get an error in GitHub Actions that indicates that CodeQL wasn’t able to analyze your code, please follow the instructions here to debug the analysis.

    How do I disable

    If you have LGTM’s automatic pull request analysis enabled, then you can follow these steps to disable the LGTM pull request analysis. You don’t actually need to remove your repository from; it will automatically be removed in the next few months as part of the deprecation of (more info here).

    Which source code hosting platforms does code scanning support?

    GitHub code scanning is deeply integrated within GitHub itself. If you’d like to scan source code that is hosted elsewhere, we suggest that you create a mirror of that code on GitHub.

    How do I know this PR is legitimate?

    This PR is filed by the official GitHub App, in line with the deprecation timeline that was announced on the official GitHub Blog. The proposed GitHub Action workflow uses the official open source GitHub CodeQL Action. If you have any other questions or concerns, please join the discussion here in the official GitHub community!

    I have another question / how do I get in touch?

    Please join the discussion here to ask further questions and send us suggestions!

  • Layout doesn't restore XY plots when multiple sources with prefixes are used

    Layout doesn't restore XY plots when multiple sources with prefixes are used

    1. Add at least two files (no matter what, a use motor_data.csv and its copy)
    2. Create XY plot with any data and also other simple data plot.
    3. Save layout (with or without data source, it doesn't matter).
    4. Delete everything and load the layout back.
    5. XY plots will be empty while simple plots will have data.

    Add prefixes ("motor_data1/") to curve_x and curve_y fields manually in layout file fix the issue, so it looks like PlotJuggler doesn't but should add prefixes for curves x and y on saving.

    Everything is ok if using only single data file, including files like turtle.csv that has prefixed data inside, PlotJuggler adds these prefixes to curves in layout correctly.

  • [Feature Request] Ability to show enum names corresponsding to ULog data point values

    [Feature Request] Ability to show enum names corresponsding to ULog data point values

    Problem description

    Screenshot from 2022-10-18 18-07-50

    Right now, it is quite cumbersome to debug PX4 flight log in things like vehicle_status/nav_state, as it is a defined ENUM, but as a log analyzer you don't intuitively know which NAVIGATION_STATE it belongs to.

    Desired Result

    This feature request is to have something like this as a final result: Screenshot from 2022-10-18 18-07-50 png

    Idea / Questions


    To implement this, like how the ULog Information message is parsed, we can include another message type that includes a mapping between the ENUM constant and it's value for each field of the uORB topics.

    You can read more about ULog Information message definition here:

    Something like:

    char[value_len] vehicle_status/nav_state::NAVIGATION_STATE_MANUAL=0
    char[value_len] vehicle_status/nav_state::NAVIGATION_STATE_ALTCTL=1
    char[value_len] vehicle_status/nav_state::NAVIGATION_STATE_POSCTL=2

    Can be included in the ULog to give info on Enum value to name mapping necessary to plot the enum name on the screen.


    Is this something that PlotJuggler already has implemented? (Showing translated 'enum name' from the raw value of the graph) @facontidavide

    FYI @bkueng
