You can specify classes and class limits for point objects and line objects. You can insert all desired classes at the same time and edit the display of newly inserted or existing classes simultaneously.
1. On the Graphics menu, click Edit graphic parameters.
The Edit graphic parameters window opens.
2. In the navigator, select the desired entry.
|
Note: You can set the option on different pages, for example under Zones > Display. |
3. Select the Classified display option.
4. Use the button labeled with the attribute name to select the attribute by which you want to classify the display.
For the selected attribute classes are displayed.
|
Notes: Optionally, for some attributes, a separate class is created for each characteristic of the selected attribute. Then the classes are automatically allocated correct default values. If you reject the automatic default setting, you can set it later via the Create classification for discrete values entry on the shortcut menu of the classification grid. |
5. Click the Redefine all classes button.
The Edit classification: Redefine all classes window opens.
6. In the Class limits section, specify the desired settings.

Distribution of class limits |
Here you can select the desired distribution of class limits. Tip You can also use the small arrow above the input fields for the class limits to switch to a different distribution. User-defined If the option has been selected, you can enter the desired class limits in the input fields. Note The class limits must be sorted in ascending order. Use the small arrow above the input fields to sort the class limits automatically. If the class limits are not sorted in ascending order, they can optionally be sorted automatically when closing the window. Equidistant If the option has been selected, you can enter values for the first two classes in the input fields next to the scale. All other limits are determined automatically according to the difference between the first two values. Each new class limit is determined by adding the difference between the first two classes to the previous class limit. If you enter a new value, the limits are recalculated immediately. Logarithmically If the option has been selected, you can enter values for the first two classes in the input fields next to the scale. All other limits are determined automatically according to the difference between the first two values. Each new class limit is determined by multiplying the difference between the first two classes by the previous class limit. If you enter a new value, the limits are recalculated immediately. Natural breaks If the option has been selected, all class limits are generated automatically. Based on the attribute values that exist in the network and the current number of classes, a meaningful classification is generated. Note The method aims at determining the class limits in such a way that each class contains approximately the same number of items. |

Number of classes |
Desired number of classes Note The right side of the scale is adjusted immediately. |
7. In the entry fields next to the left column of the scale, enter the desired thresholds for different classes.
8. Make the desired changes in the Default section (Changing the classification settings of a point object and Changing the classification settings of a line object).
9. Confirm with OK.
10. Via the buttons, adjust the settings for the display.
