C 2D Plotting Library

Question

Hello. I have a project that I haven't started yet as I am looking for a plotting library.

If there's any out there(lightweight and re-destributable) I'd be happy to use it.

It can also be a GDI wrapper.

All I need it to do is be able to draw two axes and a key representing the chart/graph data.

Any suggestions?

EDIT: The whole project is in C and not C++ and / or other managed code technologies.
However if it can be a C++ written library, that is fine provided that it exports C compatible methods (not classes).

Hope this makes it more clear now.

For such a basic task you may also consider developing your own library.

Why not just use GDI? ...it's not that hard to use... ???

I guess that by plotting you are thinging about a chart (and not something more sinister :) )
There is one project here on CP that may suit you:
A flexible charting library for .NET[^]

[Updated for c]
Cairo is a 2D graphics library with support for multiple output devices
http://cairographics.org/[^]
On the Examples page[^] - you will find links to various charting examples/implmentations

If you don't mind using GTK+ have a look at GTK/Cairo Line Graph widget[^]

I guess '.NET' would be overkill for a Win32 C project.

The question is for C. Not sure how flexible the author is on this, but I took this to mean not C++ or managed code.

You got that right. It is for C only.
