Hello,
To create a wafer map you can give X and Y coordinates of die and then plot them using graph builder and you could use heatmaps to highlight defects for example.
We have an example of this in the STIPS course, Module 2: Exploratory Data Analysis. Here is the link, watch from minute 2:15: Creating Maps Using Coordinates - JMP User Community
I have also attached the data file example.
Hope this helps!
