I have added a request for showing height in the Graph plot, this is I think the last new feature for this release.

I have been playing with another tool that can plot the power usage of the whole house..  So I need a graph widget yet again, basically the same as in GpxViewer, but that one is very specifically written for it goal.

Are there any good cairo/gtk plot libraries?   I could only find a python one.. (cairoplot)..

I decided to write a Graph widget that is generic enough to work in most of my programs, written in vala, so easy to use in other languages.

A first try:  (it combines area + bar + line plot)

When it is in a somewhat usable state I will put it online (And intergrate it in GpxViewer).
