## Purpose¶

Adds a frequency histogram to an existing graph.

## Format¶

plotAddHistF([myPlot, ]f, c)
Parameters: myPlot (struct) – Optional argument. A plotControl structure. f (Nx1 vector) – frequencies to be graphed. c (Nx1 vector) – numeric labels for categories. If this is a scalar 0, a sequence from 1 to rows(f) will be created.

## Remarks¶

plotAddHistF() 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.
