When I run make (after qmake) I get the following error.

cd alphaplot/ && ( test -e Makefile || /usr/lib/qt5/bin/qmake -o Makefile /home/archisman/AlphaPlot/alphaplot/alphaplot.pro ) && make -f Makefile

I am using KDE Neon 5.19 (Ubuntu 18.04 base). I installed zlibc and gsl-bin packages.

Could you consider to add mac retina-display resolution support into AlphaPlot, please? This would greatly enhance the user experience of AlphaPlot on Mac. Thank you @narunlifescience for your selfless contribution to this fantastic program.

Hello, This issue is for registration purposes only. As emailed to @narunlifescience, I successfully built AlphaPlot in flatpak format.

Here are the instructions for building:

1. Compile and install qtdatavis3d BaseApp:

git clone --branch=io.qt.qtdatavis3d.BaseApp https://github.com/filipestevao/flathub.git qtdatavis3d
cd qtdatavis3d
flatpak-builder --repo=qtdatavis3d --force-clean --install-deps-from=flathub build-dir io.qt.qtdatavis3d.BaseApp.yml
flatpak remote-add --user qtdatavis3d qtdatavis3d --no-gpg-verify
flatpak install --user qtdatavis3d io.qt.qtdatavis3d.BaseApp -y

2. Compile and install AlphaPlot app:

git clone --branch=io.github.narunlifescience.AlphaPlot https://github.com/filipestevao/flathub.git AlphaPlot
cd AlphaPlot
git clone https://github.com/flathub/shared-modules.git
flatpak-builder --repo=alphaplot --force-clean build-dir io.github.narunlifescience.AlphaPlot.yml
flatpak remote-add --user alphaplot alphaplot --no-gpg-verify
flatpak install --user alphaplot io.github.narunlifescience.AlphaPlot -y

I will make the pull request in the Flathub and keep informed here if everything goes well.

Hello, I really like your app. How nice its GUI is. I have just tested the newest ver. [1.0.11] and I found some issues. (1) When I dragged the graph, modified some parameters, and added arrow/text in the 2D graph, the error keeps showing up. (2) There is no option to delete or insert arbitrary cell(s) in the data sheet {like in EXCEL}. Thus, It is difficult to remove cells in one column but not delete others in the same row. (3) The reference settings for graph types in EDIT/REFERENCES cannot be saved. It reset automatically after I clicked on Apply or OK. Therefore, adjusting graph display size is painful.

I hope that my report is helpful for the improvement of AlphaPlot. If you need further information, feel free to contact me! Have a great day! LT. DUY

First, I would like to congratulate you for the AlphaPlot. I believe that this project has a promising future.

I don't know if you intend to package the application in other formats, but I packaged AlphaPlot in a AppImage:

Repository

Direct download

I know that this is not the best way to package an AppImage and it is necessary to have glibc >= 2.29 (Ubuntu 18.04 has glibc = 2.27).

I believe that a flatpak format would be even better. However, I haven't been able to compile with flatpak-builder so far.

I hope that I have contributed in some way.

Hi @narunlifescience

I have seen many good changes in AlplaPlot. Nice work!

I believe that a next release will be available soon. So, could you merge these changes in flatpak metainfo file before creating a tag? And could you inform the number and date of the next version?

Thanks in advance.

Hello. As noticeable the worth mentioning mention regards to project/organisation name is missing and then dully reported as "Unknown" when exhibited by Flatseal 'flatpak run com.github.tchx84.Flatseal'.

Edit: I'm using Version 1.011A-alpha

Thanks for making a modern version of qtiPlot. There's just one issue I'd like to point out: I'm unable to import files that use commas as decimal seperator which is a format used in some European languages. This is the csv file:

$ cat test.csv
Zeit t / s;Spannung U_B1 / V;Spannung U_A1 / V
0;0,665;-0,375
0,1;0,77;-0,29
0,2;0,855;-0,225
0,3;0,905;-0,2
0,401;0,91;-0,205
0,501;0,89;-0,245
0,6;0,83;-0,32
0,7;0,74;-0,41
0,801;0,63;-0,515
0,9;0,505;-0,625
1;0,385;-0,73

This is how I'm importing it: ↑ Please note that I'm using the correct Decimal Seperators. However the imported table consists mostly of zeros. If I perform the exact same import in SciDAVis it is imported correctly:

The appimage stunt seems surprising to me, but on the whole I have such an impression that the authors of this program practically do not test it in a clean Linux virtual machine.

All the changes

• [x] Add legend visible property in Curve2D, LineSpecial2D and Vector2D.
• [x] Add legend margins.
• [x] Add legend direction property ("Rows" or "Columns").
• [ ] Load legend title property

~Before: the legend title and font were saved, but were not loaded later.~ ~Now: the legend title and font are loaded, but only if the visible property is marked "True".~ UPDATE: this was causing crash in xml opening, so it was removed.

• [x] Fix save/load text label rotation.

Before: create a table with a Text Type, plot the graph, change the rotation of the labels and save it. When the graph is loaded, the text label has been rotated to 45º. Now: the rotation of the Text Type labels can be loaded successfully.

• [ ] Add subscript and superscript in text and labels.

It was not implemented in this PR but I would like to see this feature in the future.

The new features

• The visible property allows to add or remove the plotted curve from the legend.

• You can now choose between "Rows" or "Columns" to change the direction of plotted items.

• Using the same property as "Text", the legend margins can be changed.

• All of these features can be saved/loaded successfully.

How to set multiple X Y plots in one layer?

I have one table with X1 Y1 and X2 Y2, I want to create one graph (plot) with both X and Y. How to do that.

P. S. I don't want to create new subplot and make 2 separated plots...?

There is an error message when using a column ID that contains a special character (like Swedish wowels å, ä, ö) in the formula tab. See attached screenshot. The workaround is to use a instead of å, ä and o instead of o (but silly).

In the attached screenshot i try and use a column ID containing an "ä", in the word "magnetfält", and receive the error upon pressing "apply" in the formula tab.

I will post all the things on my wishlist as separate issues. Tell me if you want them together in the future. I work in a science center, and we will start using your excellent software (albeit with some issues) in our classrooms from next semester. So I will likely report more stuff as we discover them.

A very confusing minor issue is that the "formula" and table views uses different decimal separators. In Sweden (and the nordic countries) and Germany, we for some reason use comma (,) as a decimal separator, in contrast to the rest of the world. Alphaplot correctly displays the decimal sepator of the OS in the table view, but needs a dot (.) as a decimal sepator in the formula section. I'm not sure what the comma does when put in the formula, but it still gives a (faulty) value. It took me a while to realize this. Not sure what the best solution is. Our students are used to using comma.

As per example in the attached screenshot, it is impossible or at least unintuitive to set the axis limits to a small exponent. The value stated only shows 0,000000 (here I use the comma as a a decimal separator). Even when the significant digit is displayed, the decimal view is very cumbersome. It would be good if there is an intuitive syntax for negative and positive exponents (i.e. 3e-7 or 5-e10) for the axis.

I am writing this because I want to draw attention to the really important points, software is still written not only in order to write it.

Backend

• A serious glitch with approximation: going out of range leads to an incorrect result.

• Crashes are observed when trying to edit the approximation result.

• Gaussian peak approximation leaves much to be desired, and really works only in simple cases.

• Charts in polar coordinates never appeared in the program. You can still be the first among free origin clones)

Frontend

• The points of the approximation curve are not displayed in a separate table, and if they are, then it is difficult to understand that this is what you need.

• There is no separate table with the results of the approximation itself, such as the correlation coefficient, you have to get it from the log.

• Hotkeys don't always work as expected, but that's the lesser of the evils. I mostly miss alt+C (was in the original qtiplot) for a new column, and enter has to be pressed twice to move to the next line when manually typing.

GUI inconvenience

• The application does not remember the layout of widgets.

• The settings window in the old version was better, it's actually generally funny here. Everyone moves away from this view in their designs, you returned to it)

• The table settings window generally justified itself, but it is much more difficult to work with the same for charts. For good, both need a redesign, the main complaint is too small elements. It is possible to make duplicate layers, which should not be.

• No syntax highlighting in Approximation Wizard, parameters are not added automatically.

• Sometimes the width of the last column is naughty, stretching to the end. In my opinion, it should be wider than some x and not wider than necessary.

Wishes

• Tabs in tables as in origin pro.

• Tabbed mode as in kde's labplot.

• More human readable data format instead of xml. I would prefer to see there an ordinary archive with an internal structure, settings files and csv and other data files. Yes, it will weigh a lot, but not globally, for that people without a program will be able to figure it out.

• A slight redesign of the project browser to better fit vertically would also help.

These are the results of the real application of the program in scientific work and education, and this list is more important than porting to cmake and qt6.

In my opinion, the tester needs the team.

It is worth noting that at the moment you have done the best among the open clones of Origin Pro.

When building AlplaPlot from sources some warnings from *.desktop files are displayed. Being that two of them seem to require attention:

Running test: 35-desktop...usr/share/applications/alphaplot.desktop: warning: value "" for key "Path" in group "Desktop Entry" does not look like an absolute path usr/share/applications/alphaplot.desktop: warning: key "TerminalOptions" in group "Desktop Entry" is deprecated
