  3. Go to the Graph Options tab.
  4. Select the 3D Graph radio buttons. This graph is shown below.
    Histogram Analysis Example #3 Graph: Three-Dimensional Display

    Here, the three-dimensional graph shows a Cross-Tabulation of each bin of “income” and “age.” As an example, look at the tallest bar, the Cross-Tabulation of “income” within the range of 0-14415.7, with the age column in the range of 13-20.6. There are approximately 130 occurrences within that particular Cross-Tabulation.

  5. Click on the Graph Options tab as described above to change the axis that the columns are displayed on, and a two-dimensional stacked view of the cross-tabulated results.
