Re: [Gnuplot-info] on the color bar of the gnuplot

[Derek L. <de...@bo...>]

Hi Brett,

For your first question, I don't know that this is possible with Gnuplot, but I have only been using it for a short time myself—maybe somebody more experienced has an idea.  The manual for Key says "[Each] entry contains a plot title and a sample line/point/box of the same color and fill properties as used in the plot itself."

For your second question, you want the option "Left" to "set key".

gnuplot> set key reverse Left
gnuplot> plot "1.dat" with lines title 'short title', "2.dat" with lines title 'slightly longer title'

To get answers to your questions, I had to read the documentation… it is very thorough!

best,
Derek

I know it has used "set key reverse". Will you please let me know how to keep both the color bars and the first letter (word) of different lengths of title text aligned?
