[Gnuplot-info] Could you please help me on how to use 'set key' of my figure?

[Wenqiang L. <liu...@16...>]

Dear everyone,
My current setting is 'set key box lw 0.5 reverse Left width 1', 
however, the space between the sample point&words and the box border is 
still too large for me. I have tried to use some smaller number like 
'set key box lw 0.5 reverse Left width 0.001' in my script, but the 
width seems will not change anymore. I could not change the space 
between the key and the box borders. Could you please tell me how to do 
that?
Another question is that, in x11 terminal, I can use 'test' to see the 
results of linetype, linewidth and so on. If I set terminal to 
postscript, typing 'test' gives lots of words which is not so easy to 
understand. How can I output the illustration of the test results.
Any help would be much appreciated!

Best Regards
Liu
