I would like to display the charge/discharge power of my solar battery with a gauge or donut.
To configure the gauge or donut is easy, but what is not working very well is the colouring.
As example for a value range of -3000 to +3000 I would like to have no colouring if value is 0, green from 0 to the actual positiv value and red from 0 to the actual negativ value.
For a donut, I would like to have 0 on top (12 o'clock) and also here same colouring already described. Now 0 is at the bottom (6 o'clock) and colouring always starts at -3000.
How is it possible to achieve this behaviour?
