Creating a histogram chart diagram

The histogram chart diagram displays attributes in a histogram/bar chart, where each attribute can be visualized as a bar that varies in length in proportion to the attributes' values.

As an example, the following screenshot shows a portion of a state's counties with histogram charts showing the Hispanic population as one bar and non-Hispanic population as the other bar:

By reviewing the histogram charts in the preceding screenshot, let's note down a few things:

• The bars report each race's attribute and are colored according to the selected attribute colors
• The bar outlines are black and thin
• The histogram charts are displayed over the centroid of each polygon

These three noted items, among others that are not noted, are all customizable using parameters that are available in the Diagrams tab of the Layer Properties window. The Diagrams tab for text charts has one section with parameters that are unique to the histogram diagram type: Options.

The Options section, which is shown in the following screenshot, provides the Bar Orientation parameter. This parameter sets the orientation of the bars. The options that are available are Up, Down, Right, and Left:
