Mario,
I deliberately removed the end tick labels in on the axes, simply because I didn't think it looked so good. It appeared that changing this takes a bit of fixing of the code to make the arrowheads appear in the right place. Anyway, I'm on it, and I'll post a new version in a couple of days.

I now posted an updated version, incorporating the changes suggested by Martin. It should be available for download any day now.

Thank you John!

The option of where to put the center is a simple fix, and I'll definitely deal with that. The other issue is more serious, and unfortunately slightly harder to solve. Nevertheless, I'll give it a go.

Another limitation at the moment is that the tick marks and arrowheads tend to scale if the image is resized after the call to centeraxes.

Anyway, thanks for the feedback.

Like strcmp but slower... totally useless post. Waste of space and time.

Thank u Johan, I downloaded "centeraxes", it solved my problem.
How do I get the axes ticked from -1 to 1 please? now it's ticked only from -0.9 to 0.9.
Thanks again

Thanks. I had this problem and your code worked for me. Another code 'hack legend' also works the same way
