Hi,
In a plot, I have a curve with huge number of points. To make for good printing, i don't show symbols on curves, but rather use markers to show a select few on them.
There are other curves too. Now I want to show a legend for
  1. Only some of the curves on the plot
  2. with the symbol of markers

I know this is quite irritating a thing to ask for, but is there a way to do this! I am using Qwt6.
Thanks in advance!
