Generating an indirect representation style table

A system-linked RST is based on an attribute in a layer. To generate the RST, select an attribute from the layer to become the key; Focus creates styles for each key based on the style that you design. Focus automatically links the system-linked RST through the key.

In the Maps tree, right-click a layer and click Representation Editor.
In the Representation Editor window, choose an attribute from the Attribute list that you want associated with a style.
Tip: If you are unsure of which attribute to use, you can view a list of the layer’s attributes by right-clicking the layer in the Maps tree and clicking Attribute Manager.
Click the Generating tab and choose one of the following options from the Method list:
- Unique Values: assigns a style to each shape according to its value. Each value receives its own style.
- Ranged Values: assigns a style to all the shapes within a range of numeric values. Each range receives its own style. Choose the type of range that you want to use from the Type list. Shapes containing a NoData value are displayed using the Default RST. Enter a number of ranges by which you want to divide the values in the Number of classes box.
- The minimum and maximum values for the attribute automatically display. If you want to restrict the range available for division, enter minimum and maximum values in the Min and Max boxes.
Choose one of the following options:
- Copy styles from: uses existing styles as the basis for the representation. Choose an RST from the File list.
- Generate new styles: creates new styles. Choose a style from the Based On list.
- If you want to assign various colors to the styles, enable the Vary color check box and choose a color scheme.
- If you want to assign various sizes to the points or lines, enable the Vary size check box. Enter the size in the From and By boxes. The default units are millimeters.
