In the Row Contribution Mode, In the tooltip or while hovering we would like to see Absolute Metrics and the Percentage Metrics can be shown on the chart (using Show Values).
Currently, Both the tooltip and the chart are showing percentage which does not give an idea on the absolute value which is a problem because you might be comparing 2 bars where one has 10K datapoints and other has just 2 datapoints.
Solution:
On Hovering, we should have capability to see the absolute values for the metrics while you can observe the percentage contribution normally on the chart or by adding Show values
