Hello,

I am just looking, if you need any further assistance on this matter.

Add two seperate column series to the chart, one that encodes the positive values, one that encodes the negative values. As long as they are on two seperate x axes but share one y axis, they should line up as in your picture.

If the split between blue and red isn't 0, then split it up into 2 series based on the actual split value you want to use, and then set the ReferenceValue of the shared y axis to whatever value is the split point.
