plhist: Plot a histogram from unbinned data

plhist (n, data, datmin, datmax, nbin, oldwin);

Plots a histogram from n data points stored in the array data. This routine bins the data into nbin bins equally spaced between datmin and datmax, and calls plbin to draw the resulting histogram. Parameter oldwin allows the histogram either to be plotted in an existing window or causes plhist to call plenv with suitable limits before plotting the histogram.

n (PLINT, input)

Number of data points.

data (PLFLT *, input)

Pointer to array with values of the n data points.

datmin (PLFLT, input)

Left-hand edge of lowest-valued bin.

datmax (PLFLT, input)

Right-hand edge of highest-valued bin.

nbin (PLINT, input)

Number of (equal-sized) bins into which to divide the interval xmin to xmax.

oldwin (PLINT, input)

If one, the histogram is plotted in the currently-defined window, and if zero, plenv is called automatically before plotting.
