There are some considerations with this but we should have some way to overlay different subcharts to more easily detect differences in different samples.
Different colors can represent different samples
If the chart is the same type of chart i think we are okay to combine the scales
It might also be cool to allow a binned chart and variant chart to be overlayed but the scales will be different so I think i'll have to put one y axis on one side and the Y of the other on another.
