I want to add vertical lines to histograms plotted in the diagonal of a matrix of pair-wise scatter plots. I tried to use the graphic objects returned by plotmatrix;
[S,AX,BigAx,H,HAx] = plotmatrix(X); % X has 15 columns
subplot(15,15,1); hold on; line([1.2,1.2],get(AX(1),'YLim'),'Color','r')
etc. But so far none has worked out. I would appreciate any clue as I am clueless.
I use Matlab 2018a. Thanks.
