Histogram
------------------------------------------------------------------------
Shows a histogram chart based on data in a 2D scatter chart. 

The sample creates a 2D scatter chart with random data, and in a second
ChartGroup, develops a histogram based on the distances from each of the
data points to a set of crosshairs.  The crosshairs are generated using
moveable ValueLabels with markers (arrows) and gridlines.

Three types of distribution charts are available for histogram charts,
including Histogram, Frequency graph and a Stepped Frequency graph.  In
each case, a Normal (Gaussian) distribution can be shown for comparison
to the distribution chart results.

Statistics about the distribution are available for each series array,
and are shown for the distances from the crosshairs.

Note also, that the scatter points in the first ChartGroup are automatically
labeled using the series DataLabels.  Additionally, Rtf formatting is
used in the chart footer.
