[Gnuplot-info] splot without border, fill frame

[Tim C. <tc...@gp...>]

I need to splot pm3d (or similar) where the plot fills the .png output
size, ie. no background, no tics, no title, nothing.

For weeks now I have trawled the web, read and read, nothing, but plenty
of other people try and find the solution too. Some workaround using
image post processing software. If there is an answer I suggest it is
put into the FAQ.

There is talk about with image but never concrete examples which
demonstrate this working.

Here is a tiny example. The color oval needs to touch the image borders.

If you provide an answer, thank you.
