Max of three expressions in area chart for max static axis

[#1]

Hi!

I have an area chart with one dimensión (ID), and three expressions (GRT, AIT, AIS), and I would like to set the max value for the Y axis as the max value of the three expressions. For this, I've tried to set in the field Max Static of the three dimensions (in Axis tab) something like this:

= if(max(GRT,AIT) = GRT, max(GRT,AIS), max(AIT, AIS))

I thought that these expression would work, but it doesn't work...

Thanks in advance!

May be try RangeMax()

RangeMax(GRT, AIT, AIS)
