Hello, folks I’m using a combination of functions plot() and heatmap() to visualize a correlation matrix. Correlation matrices, by definition, are symmetric, i.e., a_{i,j} = a_{j,i} for all i \neq j. The diagonal, where i = j, always has correlation 1 since it’s the correlation of a column with its…

[image] Hugo: The diagonal and half of the plot is redundant or informative. For this reason, I wanted to plot only the upper (or the lower) portions of the heatmap. How can I do that? Maybe fill the other triangle with NaN values, since that typically suppresses plotting?

How to plot only the upper (or lower) triangle matrix in a heatmap?
