Hi,

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.

Dear Davide,

This pull request contains the LSL (https://github.com/sccn/liblsl) plugin. The plugin queries LSL stream in a local network, then behaves as a relay that passes data to PlotJuggler.

We developed this on a weekend project. See below for the contributors:

• Celal Savur (@csavur)
• Shitij Kumar (@spk4422)
• Mazin Ali (@mazinMS)

Please let me if you have any questions.

Hi Guys,

Spent the last couple of days writing this rosbridge WebSocket backend.

It's working, not airtight yet.

I'll keep improving it, I'll be happy to receive comments and help if some of you are able.

Tnx

I get this error when starting the AppImage on Ubuntu 16.04: Note: Qt5 and libx11-xcb1 are installed on my system. But should be provided by the AppImage anyway, right?

./PlotJuggler-2.3.6-x86_64.AppImage       

This application failed to start because it could not find or load the Qt platform plugin "xcb"

Reinstalling the application may fix this problem.

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. layouts.zip

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
    timestamp:double;
    // a more detailed timestamp based on google cartographer
    // and the triggersync paper
    timeEvent:TimeEvent;
    deviceState:DeviceState;
}

table LogKUKAiiwaFusionTrack {
  states:[KUKAiiwaFusionTrackMessage];
}

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.
  event_name:string;
  /// The time just before a data update request is made
  local_request_time:long;
  /// 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
  device_clock_id:string;
  /// The time provided by the device specified by device_clock_id
  device_time:long;
  /// 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)
  local_clock_id:string;
  /// The time at which the data was received
  local_receive_time:long;
  /// The corrected local time which represents when the sensor
  /// data was actually captured.
  corrected_local_time:long;
  /// Estimated duration of the skew between the device clock
  /// and the local time clock
  clock_skew:long;
  /// The minimum expected delay in transporting the data request
  min_transport_delay:long;
}

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!

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

I am using the newest kinetic debians:

Hi, It seems that PlotJuggler does not support windows any more, doesn't it?

I'm working on an old version which could run on windows, just double check if I can upgrade to the newest one.

Thanks,

Chunting

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 ) :

Any javascript expression can be used for the calculations.

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

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 !

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.

Hands down the best data manipulation software available. :)

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

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.

Correct values in RQT

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

rosbag.zip Here would be a short rosbag to reproduce the described behavior. The invalid values are in the /genesys/adma/data_scaled(status) topic.

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!

FAQ

Platform : Ubuntu 20.04 ; Ros Galatic ; PlotJuggler 3.6.0 As the title ,once I click the "OK" botton above, the program crashes.And I build it from src code and try again。the faults are like below. It seems that there is something wrong with the binding between QT5 botton box and the update publisher code segment.

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.

Problem description

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:

Idea / Questions

Idea

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: https://docs.px4.io/main/en/dev_log/ulog_file_format.html#i-information-message

Something like:
