Re: [Plplot-general] remove margins on multiple plot scenario

[Xavier C. <car...@gm...>]

Hi Alan:
Thank you for sharing your code !

I have been trying to integrate this in to my current python program
without luck, as it's already pretty complex, so what I am doing now
My program creates custom "subplot" objects and passes them through a
"pipe" that first generates the window, then organizes the plots and
finally draws them
One of the critical parts of the procedure is using plenv, which uses
itself pladv and sets a basic viewport, as per the plplot documentation
As it's hard to implement this without an example, I am trying to implement
your solution on a regular plplot example first, but:

I have some difficulty understanding your code, so I would really
appreciate if you can clear some doubts:


   - # Sets up a viewport such that xnum X ynum of them fit onto a # page.
      - I assume this sets the amount of plots that will fit in to a page X
      / Y distributed ?
   - Make the active viewport the one at column currentx and row #
   currenty, starting at the top left.
      - This sets where plots will start being drawn, starting at the top
      left ?
   - The "space" parameters (top, # right, bot, and left) specify how much
   space is to be left open at # the relevant side for annotations etc.
      - This is clear


I believe it would also be great if you could share a full example with
this implementation, if possible.

Thank you so much !

Xavier
