This is what I so much look forward to knowing, and when it comes to my mind, I feel it so exiting and it is very convenient and useful. What it is? I don't know! but I want it use it in a linux command line environment, and get it to draw a plot/chart without a X-Window or any GUI.
for example, I have some data:
a, b, c, d, e
1, 2, 3, 4, 5
when I run the utility, I can have a plot directly displaying on the terminal:
a b c d e
- - - - -
- - - -
- - -
- -
-
The '-' can be any characters like '.' or whatever.
You know what I am saying! and I believe there is a good linux tool implemented out there, for more complex dataset, to draw 2-D plots/charts in terminal like many other GUI tools do in GUI environment, and it can even draw with colored characters! but what is it? I have been looking for it for months, but I don't know yet. Please give me a kick.
Thanks,
