to fix the problem with Y-axis, just set the direction:

>> set(gca,’ydir’,'normal’);

should be the same results of

>> axis xy;

As point Dan.

Thanks very much indeed. With use of axis tick settings and grid showing I could get a log-log 2-D histogram to work fine also.

Actually you can make it plot things the correct way with

axis xy;

Just put this after the imagesc(.) line.

Hi,

I dont think that there was a mistake before, just that image does things upside down from what one might expect.

So before it plotted the correct thing but flipped upside down. Now it plots the correct thing but with the y-axis the wrong way. I can’t seem to find a simple way to fix this as the axis seems to like going from min at the top to max at the bottom.

But thanks alot this is still a very useful routine.
