plotAddHist() may only add a histogram to 2-D graphs.

This function will not change any of the current graph’s settings other than to resize the view as necessary to display the new curve.

Examples#

// Create two sets of random data
x1 = rndn(500, 1);
x2 = rndn(500, 1) + 2;

// Plot first histogram with 20 bins
plotHist(x1, 20);

// Add second histogram to same graph
plotAddHist(x2, 20);
