Histc bars show outside of axes (if xlim is narrower)

Hi everyone!

I've been coding a GUI which reads an image ("imshow") and makes an histogram ("histc" kind) in a certain axes. The problem I'm having is that if I define the "xlim" narrower than the edges of the "histc", the bars which edges are out of the limits still show up (out of the axes).

The curious thing is that I've tried putting a simple "figure" command prior to the "bar" plot and as it shows on a different window (due to the "figure") the problem I talked about doesn't occur...

One other thing... does anyone know how to do a plotyy with a plot and a histc bar in one line? I only know how to do it with a normal bar plot and then replace it with an histc bar plot (with plotty(...,@bar,@plot)).

the coding related to the histogram:

handles.edges=handles.min_ratio:(handles.max_x-handles.min_x)/9:... handles.max_x; %this vector goes from 1 to 10

data=handles.image(:); %turning the image matrix into an array

% creating the histogram values (relative counts, from 0 to 1) handles.histog=histc(data,handles.edges)/sum(hist(data,handles.edges));

axes(handles.histogram) % selects the axes cla(handles.histogram) % cleans the axes

hb=bar(handles.edges,handles.histog,'histc'); % bar plot

set(hb,'FaceColor','g') % green bars xlim([6 10]) % x values limits for the bar plot

Thank you in advance!
