The Histogram object displays the distribution of values for a data set in bar graph format. The bin labels are displayed along the horizontal axis and the number of points in each division (or "bin") is displayed on the vertical axis.
Changing which column is plotted: To change the column used in the histogram, double-click on the histogram and a dialog box will appear. Select the Bins and Counts Options Tab. Choose the column you wish to plot from the selection of columns. You can also change the histogram by selecting Additional Graph Options->Histogram Options from the Options menu.
Changing the bin size: The bin size determines the width
of the X-axis over which the data points will be counted. Adjust this number
to increase or decrease the size of these bins.
