Hi,
I’ve made an extended version of “plot_model.R” script (supplemental VStar script for visualization light curve models: it is provided as an addendum to VStar https://sourceforge.net/p/vstar/code/HEAD/tree/trunk/script/plot_model.R).
The original script is somewhat inconvenient because plotting a model requires modification of a text of the script.
My extended version has a graphical interface and allows one to select data, model and model equation(s) interactively (a model equation can be simply pasted from clipboard to a text field and plotted).
A screenshot of the script in action is attached.
The script and documentation can be downloaded here: https://drive.google.com/open?id=1Q0F5g1QaOINK_45CYAMoZ3WME3EyUYkI
Best regards,
Max (PMAK)

Hi Max
Nice! Thanks.
The example R script I wrote was meant to be fairly bare-bones, just to give people the idea of what's necessary.
I like what you've done. One thing I had to remember when I ran it was that because the app was being run under X11 on my Mac, the R model equation had to be pasted with ctrl-V (rather than the usual command-V). So, one suggestion woukd be to add a load R model equation button rather than relying upon copy and paste.

Hi David,
Thank you for the response!
I've added "Equation from file" button (see attached picture) so it is possible now to load R expression from a text file. An update is in a VStarPlotter_v002.zip (https://drive.google.com/open?id=1Q0F5g1QaOINK_45CYAMoZ3WME3EyUYkI)

Hi Max
That's an excellent addition, making it a really useful tool. Thanks! This would be a good addition to the AAVSO software directory page IMHO.
David
Hi David,
Thank you for comments!
Would you like to include it into VStar project tree?
Best regards,
Max
P.S. I'm working on improved version which will be able to save/load "workspaces" (a workspace includes a light curve, a model and model equation(s) to keep things together) and, probably, additional plotting options to tune the plot.
Hi Max
Happy to include it in the source code repository or allow you to maintain it and include it separately.
That improved version sounds great too.
David
Hi David,
I will create SourceForge entry for VStarPlotter. Then a link can be placed in https://www.aavso.org/software-directory, am I right?
Best regards,
Max
Hi Max
That seems fine to me. I would suggest GitHub vs SourceForge for anything new though. VStar still uses SF but may eventually move. It's purely historical.
I'm sure AAVSO would be happy to add a link to the software directory page but I'll leave it to Sara or Bert to weigh in on this.
David
Hi Max,
I would be happy to add a link to your code to the AAVSO's Software Directory page. Would you please also send me a brief description of what it is - just one or two sentences as with the other apps.
Many thanks!
Sara
Hi Sara,
Hi David,
I will try to make GitHub repository for VStarPlotter soon and send the link.
"What it is": it is a supplementary program for VStar which plots light curve/Vstar model/Vstar model equations (Vstar generates an equation for a model as "R" language expression) in interactive mode.
Best regards,
Max
Hi Sara,
Hi David,
The project "VStar Model Plot" is on GitHub now: https://github.com/mpyat2/VStarModelPlot
I defined it as "A supplementary tool for VStar astronomical software to plot model equations"
So the link now could be placed on https://www.aavso.org/software-directory page (if you don't mind)
Now it is possible to save a "workspace", containing data, model, and model equations into one file to restore later. Also, a rudimental "Plot options" dialog was introduced; now it allows one to define plot's header and redefine axes' titles.
Best regards,
Max
Update of "VStar Model Plot" is available. A GUI is now used "tcltk" R-library directly, without intermediate "gWidgets" layer so no additional libraries are required (works on basic R installation).
This also radically shortened startup time on some systems.
The program was tested under Windows and Linux (Debian), I have no opportunity to try MaxOS R installation.
Can be downloaded from here: https://github.com/mpyat2/VStarModelPlot (use "Clone and Download"/"Download ZIP").
