I understand the length of the bars depend the max coverages of each column. Ok that's fine.
Nevertheless the ratio of each red/green bar should represent the calculated percentage of the cell.
If you simply look at the 2nd row 2nd col, you could think. low coverage ,Close to 10%. But the percentage number gives you 55%.
This is non intuitive and wrong in my opinion. I'm not talking about the length of each red/green bar it's just about the ration red/green
