Thread Subject: Only show a few signals in legend

Hi everyone!

I have a plot containing about 20 signals. I would like to display a legend which only contains a limited number of those signals...

Example: I only want to display a legend for signal A and C

If I use a code like this:

legend(['Signal A' 'C' ])

the legend will use the line color of Signal B instead of C.

a code like this

legend(['Signal A' ' ' 'C' ])

 will display all the linetypes in the legend witout giving a name for Signal B.

Anyone has an idea?
Thanks a lot

Use the plot handles to create the legend.

H = plot(rand(10,4),'-') % 4 lines
legend(H([1 3]),{'1st signal','3rd signal'})
