Figure legend: how to prevent entries from showing?

Hi all,

My code plots a figure with a few curves, after the code finishes running, I manually add the legend like this:

legend('original', '', '', 'proposed', '', '', 'Proposed with optimisation')

So my figure looks like:

I do not need these extra lines after the 'original' and 'proposed', how can I remove the 2, 3, 5, 6th entries? Or how can I add the legend without these? i.e. a legend with only 3 entries?

Many thanks!

If the figure is already plotted, then do the following

1. Select the line which you want to make invisible in legend.
2. Then select the arrow icon from the top, this will open the property inspector.
3. Scroll down in the property inspector dailouge box.
4. click parent/child item
5. In the handle visibility salect the off option.

Your line will not be appeaar in the legend now.

h = plot(....);
legend(h([1,4,7]),'original','proposed','proposed with optimisation')

Hi Are,

The problem is I add the legend manually after the code finishes running, so I don't have

h = plot(...);

and I cannot use

h([1, 4, 7])

Any idea how to use [1 4 7] without defining h?

[Are Mjaavatten]

With your plot (or rather: axes) in focus, try:

 h = get(gca,'children')

Most likely, the lines are in the correct order, but you may have to experiment a little. Typing h(1) will show details like linestyle and marker of this line.
