Re: [Matplotlib-users] plot_surface does not work

[Chloe L. <ch...@be...>]

Would it be workable for the default to be proportional to the size of the array passed in? (suggested only because I do that myself, when deciding how coarse an investigative plot I can get away with.)

Is there a reason the default rstride and cstride aren't 1 other than possible memory constraints for large arrays?

I would think that the default should be that the obvious command "just works" while plots that may require too much memory can be tweaked to work faster (I'm assuming that is the reason for the default of 10).

There is an existing PR to change the default behavior to be somewhat "automatic".  At the time, I wasn't really in favor of it, but when looked in this light, it does make some more sense.
