Hello

In a plot containing 6 line object with different colors I've created 2 hggroups to use in the legend. The 2 colors legend subsequently shows belong to the last 2 line objects. Nothing new there, but I would like legend to show for a given hggroup a color that corresponds to one of its child lines.

This image illustrates the problem: http://img203.imageshack.us/f/latconstraint.png/

Thanks for any help.

Erik,

You need to set the handle visibility of certain lines to off:

set(line_handle,'HandleVisibility','off')

When you set the handle visibility of a line to off, the legend command will not use that line when creating the legend. So if you set the handle visibility of 2 of your red lines and 2 of your green lines to 'off', legend will only use the handles for the remaining red and green line to draw the legend.
