"Based on the McCode repo checkout that I have made available, please make an alternative variant of the tools/Python/mcplot/html plotter that takes two simulation folders (a,b) as input and subtracts identical monitor outputs from each other (i.e. something like diff.mon1 = a.mon1 - b.mon1) and make a corresponding set of plots. The existing plot tool uses the mccodelib library present in tools/Python/mccodelib"

A set of demo outputs can be browsed at https://tmp.mcstas.org/diffplots/ Datasets A2 and A3 are identical, differ from A only by seed. |

Declaration of use of AI-tools
As also stated in the commit-log I used Claude to initiate the work on this tool:
"Based on the McCode repo checkout that I have made available, please make an alternative variant of the tools/Python/mcplot/html plotter that takes two simulation folders (a,b) as input and subtracts identical monitor outputs from each other (i.e. something like diff.mon1 = a.mon1 - b.mon1) and make a corresponding set of plots.
The existing plot tool uses the mccodelib library present in tools/Python/mccodelib”
I have then reviewed the code and tested locally, adapting details in the implementation.
