Hi Stuart,
Yes you can easily produce this plot. There are two options:
1. You can use the Heat Map series (check out "Chart gallery \ Heat map" examples).
2. You can use a NRangeSeries by adding ranges that correspond to each square in the heat map grid (check out "Chart gallery \ Range" examples).
We hope this helps - let us know if you meet any problems or have any questions.
Best Regards,
Nevron Support Team
