GD::Graph: How to invert Y axis

[cadbilbao]

Hi.

Working with GD::Graph::lines, I want to make a graph of historical
ranking data. I've got:
@dataArray = ('4', '3', '5', '1');

But when making the graph, '1' appears at the bottom of the the image,
and I want it to appear at the top, because it's the first position
of the ranking.

I want to invert Y axis, and make the biggest numbers appear at the
bottom, not at the top.

I've been browsing GD::Graph docs:

http://search.cpan.org/~mverb/GDGraph-1.43/Graph.pm

but I didn't find any tip to do it.

Any suggestion? Thx.

Can you post a bit more code? GD::Graph takes arrays of references to arrays as it's data but you're only showing a single array. Also, what subtype (lines, area &c) are you using?

Yours,

Thanks for the pointer, Paul. cadbilbao - it seems that people have asked you nicely not to cross-post before and you have ignored them. Why do you now expect them to help you?
