Is there away around this, that would allow me to still have a vector format that can be zoomed in without much loss of resolution? July 29th, 5 Comments.

The image plotting works only for equally distributed rectangular grids, just like any bitmap image is arranged. Using two different y-axes. Talking to gnuplot with C.
