Stacked column chart - line based on data

[BIbigbox]

Hello everyone, 

I have the following stacked column chart:

and I would like to add a line, showing exactly where the bar turns from red to green. 

I tried turning it into a line and stacked column chart, but then I lose the color saturation part of it, which is important. 

Any ideas?

Thanks in advance!

Hi @BIbigbox,

Can you share a dummy sample, please? Then we will know why the colour is green or red. Finally, we can find some indicator. 

Best Regards,
