Value Legend
A value legend can be displayed for the selected layer if a Value Expression has been defined.
In this example, a value legend is displayed for links where the link value is "[auto volumes] volau". First, select the link layer, click the Properties button, select the Value tab and enter "[auto volumes] volau" as the Value Expression. Set the Scale factor to 200 and press F5 to refresh the network plot.
Then, select the Value Legend tab and enter a title for the legend. You may also include a wildcard as part of the legend title. You can position the legend in one of six positions; the none, top-left, top-right, bottom-left or bottom-right of the print box, or free-floating on the plot. A legend is free-floating if you drag the legend to another part of the network plot. If none is selected, then the legend is not displayed.
The result is a plot that should look something like this.
