Viewing the plan histrogram

The plan histogram lets you view a histogram chart that contains the total population per district and per demographic. The histogram chart lets you view a comparison of the total population in each district and lets you modify district plans to produce a balanced representation of demographics.

Steps:

1. On the Review ribbon, click Plan Histogram.

   The Plan Histogram dialog box opens.

   The plan histogram is divided into selected district captions (for example, districts, precincts, or territories) and displays only the demographics that are turned on in the Demographics dialog box.

   Note:

   You can click the slider dial to change the visible districts on the histogram as shown in the image above.

2. Navigate the Plan Histogram dialog box at the demographic level:
   • Hover the pointer over a bar on the histogram to view a ToolTip. The ToolTip shows the district for the bar and the total count of that district.
   • Slide the scale slider to change the number of demographics that can be viewed at one time. The maximum demographics that can be viewed at one time depends on the number of demographics turned on in the Demographics dialog box. The minumum demographic viewed at one time is one. When you click on the scale slider, a number indicates how many demographics will be viewed.
   • Use the slider bars to pan through the histogram for each demographic.
3. Slide the Base Value slider to the desired population value for the histogram.

   The Base Value slider lets you adjust the starting value for the histogram. The minimum base value is 0; the maximum is equal to or less than the population in the smallest district.

   Note:

   If Unassigned or any district has a population of 0, the base value cannot be changed from zero. You can alternately hide the Unassigned or district that contains the 0 population to adjust the base value.

   Adjusting the base value lets you granularly view the population discrepancies by adjusting the starting value of the histogram. You will also see a target population line to let you know whether districts are over or under the target population.

4. Check the Show total option to display only the total population in your district plan.
5. Export an image of the chart by clicking Export (Optional).
6. Select the export image DPI:
   • 96
   • 150
   • 300

   The dots per inch (DPI), lets you define the resolution for the export image.

7. Select an export image file type:
   • JPG
   • PNG
8. Click OK.

   The Select location for download... dialog box appears.

9. Navigate to a location to store the export image.
10. Update the name for the export (Optional).
11. Click Save.

    The exported chart is saved to the image file in the output directory and format type defined above.
