[rrd-users] Can this kind of chart be drawn with RRDTool ?

[Jean-Yves Avenard]

Hi

I'd like to draw something like this:
http://i46.tinypic.com/5bd3et.png

Pretty much, it's a solar power chart ; the backround would show the
ephemeris of the Sun ; dark when it's night time, gradually lighter
and then a different colour.. Pretty much using gradients.
The grid would be drawn on top of it...

The x-axis would use noon rather than 12..

And finally, what I'd like to do is smooth a bit the curve ; even with
the slope mode on it's still very jerky. Obviously the graph would
never curve back in time like it does on that picture :)

Just trying to draw stuff with a bit more style over the precise
accuracy of the chart ...

Thanks !
