Scatter Chart colour code based on Selected Values

Hi! Im currently working in a dashboard which has the following behaviour:

In the first page, you select and filter data and then go to another page with drill through.

In that second page, I want to show the previously filtered data in a scatter chart which colour code is based on the distribution of the selection, i.e., i need to know the maximum value of the selection (this would be 100%) and calculate the colour code based on it.

In order to do this, Ive managed to obtain the maximum value of the selection in a measure, but its not possible to use it in a calculated column to recalculate the rest of the percentages.

Any idea on how to do this? Any help would be highly appreciated! Thanks
