Graph line

[ddaddy]

There's a few graphs in the charging section were the lines show a gradual increase whereas it should stay at zero until the first figure.
See attached image, the yellow line should be doing what the green line is doing as I plugged the car in at the point the green line started moving upwards.

Set fill(linear) to fill(0) or fill(null).

I set fill(linear) to fill(null) but no effect. Also tried fill(0). Am I doing something wrong?
