How to graph "total measured light"

[Kevin Crivelli]

Running the Belchertown skin I would like to be able to create a graph for total measured light per day. I have an Acurite Atlas and via their web interface I am able to see that specific set of data in a graph but I'd like to be able to create that same graph in my Weewx set up. Does anyone have an idea on how to do this or has been able to?

Here is how this looks in "My Acurite"
