I have this simple problem: I have two data frames, one df_signal with columns (row, column, intensity), the other df_det with (row, column, detected), where "intensity" is a float and "detected" is binary 1 or 0.
I'd like to overlay the df_det data frame over the df_signal frame in a heatmap, where cells that were detected have a frame around them.
I'm also happy to use a plotting library other than seaborn, if this makes it easier.
