How to not include an item in a legend

Is it possible to change whats displayed on a legend. Im plotting 3 data sets, but data set 1 and 2 are the same, only that data set 2 plots over dataset 1 with a black box if a certain condition is met.

I therefore want to remove dataset2 from the legend?

Thanks for any pointers

Done it...

For dataset1 use
h1=plot....

for dataset2
h2=plot....

and for dataset3
h3=plot

then use
legend([h1,h3],'item1','items2','Location','bestoutside','Orientation','horizontal')

ok, here's the solution: you can tell legend() with which plot handle the legend entry is associated, by:

clf;
plot(rand(10,4));
a=get(gca,'Children');
legend([a(4);a(1)],{'bla','bli'})

note that the first created plot is at the last index of the children array

Thankyou for you time anyway. Jason

Answer 3

you could add the data set with the black boxes at last and then only define 2 legend entries.

I tried that first. My first data set is big squares in blue.(dataset1)

If a condition is reached, then I want these squares to be red or black (represent extremes).I then plot again within an if/elseif statement. This is my dataset 2 (that I don't want on the legend)

I then plot a green Cross ontop of the squares for another data set (dataset3).If I do your suggestion, then the crosses are not seen.

I've tried this approach by calling my dataset 2 via

h2=plot.....

hsAnno = get(h2, 'Annotation');
hsLegend = get(hsAnno, 'LegendInformation');
set(hsLegend, 'IconDisplayStyle', 'off');

But no joy
