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 points, you may change the width of points, their color, and whether to display missing values. You may use point width and color to represent the values of two different variables in a thematic map.
You can choose to have all points the same width (choose "Single width" and the size in pixels from the drop-down box). Or, you may use the size of the points to indicate the value of a variable (choose "Graduated width using single variable"). If you choose graduated width, you need to choose a variable from the drop-down list and choose the minimum and maximum point sizes from the lists.
You can choose to color all points 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 points using the values of a categorical variable. Once you choose the variable to represent, BoundarySeer will choose the colors.
Missing values are indicated with a special symbol on the map (the default symbol is an empty circle with a red outline). You may choose not to show missing values on the map, if so, clear the box at the bottom of the dialog.
