This isn't anything urgent.
I have been looking into gnuplot and I have made a little progress.
I'm wondering if I can generate a plot png file and have it selected almost immediately for the viewer pane.
My motivation for this is more for png files for Physics videos, but the idea of Directory Opus 2D, nice 3D illustrations, and perhaps a toolbar ( I only have a few command line things working so far ) could be something on the future horizon.
This should be possible with the OnFilesystemChange event.
Thankyou.
It was only a thought I had at the moment and I will keep this in mind.
I have made more progress on this today. I am now able to to make a Directory Opus button that uses a text file of gnuplot commands that creates either a pop-up graph or a png file.
The result does not leave an open gnuplot GUI.
Contrary to what the gnuplot documentation may seem to be, there is no command line switch needed before the quoted text file that contains gnuplot commands.
Using the suggested one (-c ) doesn't work.
How it is best to implement this idea and for what specific task is still an open question.
I have a few ideas, but the data string or text file is yet another area for me to think on.
I think I may be able to take a go on a few things using Evaluator and Dopus variables.
In the end, a script is probably going to be the best answer, but I'll see what I can do with Evauator and post anything perhaps worth something.
Oh, and that nice 3D box plot is in the Demo folder with a text file of the command code.
It references a data text file. I can do that Demo now using a Directory Opus button.
I'm doing a little better now.
I can now make js text files for data thanks to hacking @lxp old exiftool helper file script .
Not very much different from what I remember from PHP.
All you need to do is double click a gnuplot command file with the extension of gp to get an immediate graph. Of course png is also easy.
I wish I could use command line to introduce what is called a data block, but I'm still short on that.
I'm still working on it.
And yeah I have a long way to go.
If I find a use for this that is worth something I'll post it, but don't hold your breath.
My solution is only making a text file, not using anything else as source for data
Edit note:
Of course we can do this the old way with a user command that executes MS-DOS to make the text ile and/or append. Echo >>
