Visually Compare Plans

iRedistrict uses the data list, scatter plot, and parallel coordinate plot (PCP) for plan comparison. Within the Plans tab in the Right Panel, you can click on a point within the scatterplot, cross a line on the parallel coordinate plot, or select a number on the ranking list to update the map with the selected plan.

Scatterplot

To compare plans using the scatterplot:

1. Click the Right Panel > Plans.

2. The two axes of the scatter plot can be any two of the chosen criteria (e.g. population and compactness). Choose the measurement for x-axis and y-axis of the first plot (scatterplot).

3. Each point on the scatterplot represents a plan. Click on a point so the corresponding plan will be shown on the map and highlighted in the parallel coordinate plot.

Parallel Coordinate Plot

When using the parallel coordinate plot (PCP) for comparing multivariate data within a plan, each axis represents a variable used in the optimization criteria whereas each line represents the scores of related criteria for a specific plan. The selected plan will display as a red line and the other generated plans are displayed as blue lines.

To select a plan within the PCP, click and drag the mouse over its representing line. Once the plan is selected, the representing line will highlight in red. The plan’s information will update in the map and report, and its related point in the scatter plot will highlight in red.
