<P> Histograms can be plotted quite easily. At present the histogram plotting function, <code>plhist</code>, will plot histograms of the columns of a matrix. For example:

<P> <PRE> &gt; // Create data &gt; rand("normal", 0, pi); &gt; r = rand(2000,1); &gt; &gt; // Create plot &gt; ptitle("Histogram, 30 Bins"); &gt; plhist (r, 30); </PRE>
