To display a graph, follow the steps below:

  1. In the Location pane, select the location in the Location column. If you want to see only part of the route, adjust the mile points and/or lanes and/or direction.

    Note: Data may only be displayed for routes that belong to the administrative unit you selected when you logged on.
  2. In the Measure/Index pane, select the index or indices you wish to graph by clicking the check box beside each index.
  3. In the Year pane, select the year or years you wish to graph by clicking the check box beside each index.
  4. In the Location pane, right-click and select Show Data and Graph. The system then draws curves for each combination of index and year selected in the Measure/Index and Year panes for the selected route. It also displays data in the Data pane.

The following table summarizes which records are graphed depending on the selections you make for the Direction and Lane columns. For example, setting the Direction column to Increasing and the Lane column to All will result in all records where Direction = All or Increasing AND Lane = All or 1 being graphed.
