To bring up the properties dialog, you can double-click on the layer list or right-click on the middle pane of the map and choose "Properties".
For line layers, you may change the thickness and color of line layers. Single value and single color are the defaults, though graduated thickness and graduated color are available for data sets that have more complexity. You may use line thickness and color to represent two different variables.
Many BoundarySeer line layers, however, will be spatial features without associated data.
You can choose to have all lines the same width (choose "Single thickness" and the size in pixels from the drop-down box). Or, you may use the thickness of the lines to indicate the value of a variable (choose "Graduated using single variable"). If you choose graduated thickness, you need to choose a variable from the drop-down list and choose the minimum and maximum thickness in pixels from the lists.
You can choose to color all lines the same (choose "Single color" and the color using the "Change Color" button). You may also show the values for a single numeric variable using graduated color. For graduated color, you choose the variable and the minimum and maximum colors. The default is to grade from gray to black, but you could choose any combination of minimum and maximum colors, such as white to green:
The last alternative is to color lines using the values of a categorical variable. Once you choose the variable to represent, BoundarySeer will choose the colors.
