MATLAB: XLim for bar plot with several data series

Question

I created a bar plot with three data series and bins 0 to 20. The automated process creates a plot with bins -5 to 25. I'm wondering why and I'm wondering how I could set the XLim property? b = bar(…) and b.XLim doesn't work. b(1).XLim doesn't work either.

bins = 0:20  
figure;
b2 = bar(bins,[s1 s2 s3],'hist','FaceColor','flat');

s1, s2, and s3 are vectors (data series).

XLim = [0, 20];

gives me the following error message:

Expected one output from a curly brace or dot indexing expression, but there were 3 results.

Otherwise:

b2(1).XLim = [0, 20]
Unrecognized property 'XLim' for class 'matlab.graphics.primitive.Patch'.

As well as:

b2(1).XLim = {[0, 20] , [0, 20] , [0, 20]}
Unrecognized property 'XLim' for class 'matlab.graphics.primitive.Patch'.
b2.XLim = {[0, 20] [0, 20] [0, 20]}
Expected one output from a curly brace or dot indexing expression, but there were 3 results.
b2.XLim = {[0, 20] ,[0, 20], [0, 20]}
Expected one output from a curly brace or dot indexing expression, but there were 3 results.

Does anyone know how I can set the XLim value? It works with the Plot Tools.

Thank you very much in advance!

Answer 1

ax = gca;
ax.XLim = [0, 20];

Did the trick! Thank you Star Rider, you brought me onto the right path!
