Correlation matrix not working properly when using plotmatrix(X)

[xarico10]

When calling plotmatrix(X) to create a matrix of subaxes containing scatter plots of every X variable against the rest, and containing an histogram on the diagonal, apart from the visual issue (#206), such histogram isn't being plotted and a self-related scatter chart is being plotted on the diagonal (which makes no sense).

X = randn(50,3);  
plotmatrix(X)

Expected and generated (https://chart-studio.plotly.com/~xarico10/523/#/) plots
