Unable to graph data for solar energy today

[jeremyquinn]

The problem

There is a sensor In the Growatt integration, to output the quantity of solar energy generated today, on my system it is called : sensor.ooctcl60bp_solar_energy_today.
I am able to show this data in a guage.
I have been trying to compare this value with the solar forecast estimate : sensor.energy_production_today in a Statistics Graph, however the value is not usable, the solar estimate works.
The documentation claims that the cause of this is a configuration error and asks that I report this as an issue on GitHub.
