Set some legends of a line plot to invisible

Hello,

I'm plotting multiple lines with the command:

line([Min Min], [minY-20 maxY+20],....);

The variables used in line are all vectors. When adding a legend to this plot Matlab adds for each line an entry in the legend box but I want to show only one entry for all lines.

How can I do this?

can you upload the code?

There are multiple ways of doing this. The easiest way is to only pass one of the output handles to legend()

h = plot([Min Min], [minY-20 maxY+20],....);
legend(h(1), 'Some Legend')

Other ways include setting the IconDisplayStyle of the other handles to 'off'

The icondisplaystyle approach can also be used in R2014a and earlier; see https://www.mathworks.com/matlabcentral/answers/406-how-do-i-skip-items-in-a-legend

Dear Walter,

thank you for the tip.

I didn't know this setting of the Legend function.

It really helped me with a bar plot's legend too.

Best.
