[Gnuplot-info] Color legend for lc variable

[Debostuti G. <deb...@gm...>]

Dear Gnuplot Community

I am using the following command to plot my data with a set of variable
colors.

splot "Params.dat" using 3:6:1 with points pointtype 7 pointsize 1 lc
variable linewidth 5

I had two questions regarding this:

1. How do I show a legend on the graph that indicates the value each color
signifies, something like what we get using cbrange and palette?

2. How do I set the colors to particular ones instead of the default colors
specified by lc variable?

Thank you
