Barcharts colours based on other vectors

43 views (last 30 days)
Hi all,
I have 3 vectors a,b,c with 4 numbers in each of them
I create another vector d with all the values of vectors a,b,c Sorted.
then I want to plot a barchart of vector d, BUT I would like to have different colours in the bars based on which vector they belong.
Can you help me with this?
for example:
values belong to vector a=green colour
values belong to vector b=blue colour
values belong to vector c=orang colour
Hope the quesiton is clear
thanks in advance
Nikolas

This has been addressed before within the forum (example1 ,example2).
The basic idea is to store the output handle to the bar objects
bh = bar(____);
Set the FaceColor to flat
bh.FaceColor = 'flat';
Redefine the CDdata which defines the color of each bar
colorData = bh.CData; % Current color arrangement.
% Example: change color of bar #2 to red
bh.CData(2,:) = [1 0 0];
% Example: define the colors based on the jet colormap
bh.CData = jet(size(bh.CData,1));
