Re: [Gnuplot-info] Series labels from data file?

[Steve C. <sc...@ja...>]

Well, I was able to build, even on RedHat, but it creates a very small 
set of terminals. Missing are any
ubiquitously displayable filetype terminals such as png, gif, or jpeg. I 
also built on Ubuntu, which at least provides png and jpeg. What governs 
this and what can be done about it?
