Gauge that fills from the centre to the left and right

[kenhs26]

I have a sensor that measures the power being imported (negative value) or exported (positive value) from the grid. I would like to display that with a fill that is in the centre of the card when the value is near zero and then either fills left if the value is negative or fills to the right if the value is positive.

Ideally, the zero point would be determined by where zero falls between the min and max values. So, min = -5,000 and max = 10,000, the zero point would be 1/3 of the width.
