I am plotting an upper triangular matrix where the bottom half of the matrix is full of zeros. The heatmap as it currently stands looks like the following
I would like to just essentially fold this in half however I am stumped on all fronts as to how to approach this. I realise this is quite an ask however I know there are some incredible things you can do in MAKIE. Then again this could be an algebra question of how to extract the upper triangular part of the matrix.
