Visualize delta between two thermal maps

I’ve been doing outdoor comfort studies, and often you are comparing two scenarios. It would be really useful to see the difference in temperature between these two scenarios, and I often see this in thermal maps in research papers.

Is there a way to do this currently with ladybug?

I’ve tried a couple approaches but it’s very manual. Can get different csv files from different runs of the simulation and import them back into the script, then calculate the delta and re-export, finally reading that into HB Read Thermal Matrix.

(side question: if there’s a way to write to text file from MacOS let me know…been bugging me that no plugins or scripts that do this are floating around)

You can load both values to Grasshopper, subtract them from one another, and then create a new visualization set or colored heatmap.
