I did, but the Area component has a  dataFieldFrom and To  (2 variables), but only a single displayText – the demo does not alter the pop up graph tip labels when you hover over a point. It still says Low and High – which are the actual variable names – only the legend changes to say Temperature Range.
I would like to change the y1 and y2 in my example, to Min and Max in the ToolTip that pops up.  For now I called y1 ‘<‘ and y2  ‘>’ – but text would be better. I don’;t weant to actually call them min and max in the dataset, in order to save RAM space in the embedded device.
Thanks
