Break in the axis

Hi

I have a plot of data points (x, y). The issue is that one of the first data points has a very large amplitude, whereas the rest of the data points have very small magnitudes. So what I thought that I wanted to do is to make a "cut" in the y-axis, such that it goes from 0..1 and then skips to 100..105. Perhaps with a mark such as this "----//----" in between.

Is that possible in MatLAB?

Best, Niles.

There is no direct function as I know.

But you can try to plot the double line on your figure.

for example,

x=1:10;
y=sin(x);
plot(x,y,'k*-','LineWidth',1.5,'MarkerSize',8);
axes('Position',[.1 .78 .05 .05]);
px=[1 5];
py1=[1 2];
height=1;
py2=py1+height;
plot(px,py1,'k','LineWidth',2);hold all;
plot(px,py2,'k','LineWidth',2);hold all;
fill([px flip(px)],[py1 flip(py2)],'w','EdgeColor','none');
box off;
axis off;

Then you can get the follow figure.

It does EXACTLY what you want to do.

That's what Thomas suggested 6 years ago.
