Changing the colour of a legend on the fly

How do I manually change the colours (all different) of all the items in a legend. I know how many there are (n). This is my attempt

hleg=findobj(gcf,'Tag','legend')
switch n
   case 1    
    set(hleg, 'TextColor','r')
   case 2
   set(hleg, 'TextColor','b')  
   case 3
   set(hleg, 'TextColor','r') 
   case 4
   set(hleg, 'TextColor','k')

    end

but it changes all of the items colour to the same colour.

uhm, I think that there is only one color property for all the text in a legend.

Anyway your code would not work. Switch chooses one of the instructions based on the value of n.

In principle, you should use a loop over n instead of a switch. But as I say, as far as I know, there is no individual color for the (text) items in a legend.

The symbols are colored, but their color is "synchronized" with the corresponding data.

I plot my first data first, then add the legend, then plot second data and then add second legend but obtain the first and concatenate.

i.e

axes(handles.axes1)
colour='r'
plot(x,r,colour,'MarkerSize', 1, 'Marker','o','LineWidth',1)
legText=get(handles.editLegend,'String');

then for the second data:

legText='MyNewData';
txt1=get(legend(gca),'String');
txt1=[txt1,legText];
hleg=legend(txt1);

I do it this way because sometime I want 3 or 4 data sets, so I just concatenate.
