Setting DisplayName for a bar graph

108 views (last 30 days)
When using the plot() command, one can set the DisplayName property of the plotted lines, and display them in the legend, like so:
hp=plot(1:10,[1:10;2:11]','DisplayName',{'line 1','line 2'});
This approach does not work for a bar graph:
hb=bar(1:10,[1:10;2:11]','DisplayName',{'line 1','line 2'}); % Error!
I know I can "get" the DisplayName property of the bars, like so:
But is there a way to set the DisplayName property in a vectorized way?
I tried
set(hb,'DisplayName',{'bar 1','bar 2'})
but the syntax requires a string input there, and balks at the cell array.

The help for set says:
set(H,pn,MxN_pv) sets n property values on each of m graphics objects, where m = length(H) and n is equal to the number of property names contained in the cell array pn. This allows you to set a given group of properties to different values on each object.
In this case the length of H is 2 and we're setting 1 property. Therefore the cell array of property names pn will be 1-by-1 and the cell array of property values pv will be 2-by-1:
set( hb, {'DisplayName'}, {'foo'; 'bar'} );
legend show

figure1 = figure; axes1 = axes('Parent',figure1); hold(axes1,'on'); bar1 = bar(data_here); set(axes1,'XTickLabel',data_cell_array_labels_here);
It needs to set the "axes" not the gcs or the DisplayName!!
