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).
