Histogram

A histogram plots the values of a selected attribute along the x-axis against frequency counts along the y-axis. To create a histogram:

1. Click Histogram.

2. Enter the following information for the histogram:

   • Title: This is the name of the histogram. You can use the default name or you can enter a different name.

   • Comment: Enter a description of the histogram. This is an optional field.

   • Specify the following settings for the Histogram:

     • X-Axis: Select an attribute to plot along the x-axis of the graph. This attribute is handled using either Top N, or Binned (the default). To specify handling, click Settings.

     • Group By: Click Group By to select an optional Group By attribute. This attribute groups values in the bin (stack the bar).
       To specify how Group By is performed, click Settings.
       By default, a histogram with a Group By attribute is displayed as a Stacked Bar Graph.
       Click , the Stacked Bar Graph icon, and select the Dual Y Bar Graph icon.
       If you specify an invalid value, a message appears explaining the problem.
