Enhancement request kWh/m^2 per day graph

Hi Steve, would it be possible to have another graph to show kWh/m^2 per day for the past month, like the daily sunshine hours graph? It can be directly calculated from the solar radiation, and would need to be midnight to midnight, rather 9am to 9am. It would accumulate through the day, like ET, so maybe it could also be displayed in the Solar section at the bottom of the main display page, although I can see it might be a bit of a squeeze ;)
It would be useful for people who generate electricity with solar panels, currently the only publicly accessible kWh/m^2 data is the daily estimate from satellite images (in Australia anyway), and not everyone is close to the places they estimate it for.

thanks.

Yes, it would be possible, but I don't think there's any way it's going into the solar panel. Maybe in the heading for the panel, or in the mouseover along with the current theoretical max. I think there is already an enhancement request for this.

Gordon,
Have you considered using one of the 3rd-party graph packages to generate graphs using data from your station?
A 'freebie' that springs to mind is jpgraph.

Yes, I did have a bit of a look at JpgGraph some time back, but was hoping for something that was integrated into Cumulus, so the graphs were all of the same design/appearance, rather than an add-on for one or 2 graphs.
