[rrd-users] unusual chart type ?

I am wondering how much effort it would be to display a time series with
two variables in the following way:
* horizontal axis = days (e.g. 03/01/2009 ... 03/31/2009) as
vertical bars over the whole height
* vertical axis = time of day ( 00:00 ... 23:59)
* the values of one variable would be color palette coded
* the values of a second variable would be overlayed as contour plot
I've realized this kind of graph using "R" before.
I use it e.g. to show how the day-by-day-trend of a photovoltaic
inverter's mode switching timepoints
are related to the daily sunshine intensity.
Is there a name for such a plot?
Anyone done that before?
Anyone has an idea how to do it?
I've not yet done much with rrdtool, but if you consider it right to do
this, I would spend the necessary time.
Many thanks in advance,
