Conditional color for more than 1 column in clusterized chart

For default, we have the conditional color of a column into the clusterized chart and it's very helpfull.

However, this works only when you have just one data into de Y axis.

Including the possibility of use the same conditional method for more than 1 column into Y aixs, will be greater.

For example, if we have expenses, income and profit, actually the user can't define the color of the profit based on the value will be more than zero or not.

Just because the 3 informations are in the Y axis.
