MATLAB: XTick labels for bar plot of 2 data sets

Question

I want to make a bar chart with 2 data sets that have different number of values and I want each set to have the same color. Example code:

figure, bar([1:5],rand(1,5),'b'); hold on
bar([6:12],rand(1,7),'r')

The bar chart shows the XTickLabels for the first data set but not the second. How do I get XTickLabels for all 12 bars?

If I make a bar chart with a dataset with 12 entries, I can't change the colors of some bars, for example bars 1 – 5, so I had to break it up and make 2 bar plots.

Hope this makes sense.

Thanks!

Answer 1

One way is to concatanate the 'XData' vectors of both series, and use that as the 'XData' value for the first (blue) bar series, then plot both series:

figure
hb1 = bar([1:5],rand(1,5),'b'); 
hb1.XData = 1:12;
hold on
hb2 = bar([6:12],rand(1,7),'r');
hold off

This also works even if the 'XData' vectors are not continuous:

figure
hb1 = bar([1:5],rand(1,5),'b'); 
hb1.XData = [1:5 7:13];
hold on
hb2 = bar([7:13],rand(1,7),'r');
hold off
