Re: gnuplot windows term issue: point size

[Sebastian P. <spc...@gm...>]

I don't get it. Why point size cannot be fixed? The line weight can be
set and it is const. even when resizing window, but the size of the
point is totally ignored!? Points should be autoscaled or at least
they should keep fixed size. In Gnuplot their size is impredictable.
Another win term bug?
