BreakPlot(x,y,y_break_start,y_break_end,break_type)
Produces a plot who's y-axis skips to avoid unecessary blank space

INPUT
x
y
y_break_start
y_break_end
break_type
if break_type='RPatch' the plot will look torn
in the broken space
if break_type='Patch' the plot will have a more
regular, zig-zag tear
if break_plot='Line' the plot will merely have
some hash marks on the y-axis to denote the
break

USAGE:
figure;
BreakPlot(rand(1,21),[1:10,40:50],10,40,'Line');
figure;
BreakPlot(rand(1,21),[1:10,40:50],10,40,'Patch');
figure;
BreakPlot(rand(1,21),[1:10,40:50],10,40,'RPatch');
figure;
x=rand(1,21);y=[1:10,40:50];
subplot(2,1,1);plot(x(y>=40),y(y>=40),'.');
set(gca,'XTickLabel',[]);
subplot(2,1,2);plot(x(y<=20),y(y<=20),'.');%

IT'S NOT FANCY, BUT IT WORKS.

how one can break the Yaxis into more than two pieces

Is it possible to use this for hist function?

One small addition: If your y data has a large range and you want to skip a lot (e.g. several orders of magnitude), then the mid point might not be suitable for breaking. In my case the upper part got way too much range compared to the lower. Can easily be adjusted by tweaking the 'y_break_mid'. I used e.g.

y_break_mid= y_break_end - (y_break_end-y_break_start)./10;

Great code, helped a lot, Michael!

Thank you very much!

Giuseppe Sanfilippo

Well done, but It does not work when y is in a negative scale, i.e. y \in [-1000,0]

Excellent,
Thank you

very efficient, and useful. Nice work

Nice, useful function! Would be nice to have the same for breakxaxis. (With the same patch options.)
