I wondered if anyone can point me in the right direction. I have a script that creates a table with Row, Column and Data fields (multiple Data field values for each (Row,Column) pair). I'd like to be able to create a Heat Map showing the Range for each Row and Column pair. By default the Mean is plotted. I can create an aggregated field (sum, median, std deviation and some others are included but not Range). Does anyone have any tips for how I might do this. Thanks, Mark
