The interface for editing a enumerated rule looks like this:
Specify Whether the Rule Is Used in the Inference
Check the box next to "will be in used" to make the rule be used in the inference. Uncheck the box to disable the rule.The rule is editable only when it is in use.
Edit the Rule
All of the current enumerated items are listed in the list box. To add an item, click on "Add". In the pop-up dialog, enter the item (an integer number)
Click on "OK".
To remove an item, click on the item in the list box, then click on "Remove",
The editing will be reflected in the graphic area.
You can also modify the rule in the graphic mode. Current mouse location is displayed in real time on the right
To change the value of an item, drag the green bar to the position and release mouse.
To add an item, double click on the location where the new item is to be added.
To remove an item, double click on the bar that represents the item to be deleted.
Set the Display Range of the Graphic Area
Display range decides the maximum range on the x-axis of the graph area. To set the display range, use the arrows at each end of the display range control bar.
On the left, click on "<" to decrease the low display limit, click on ">" to increase the low display limit.
.
On the right, click on ">" to increase the high display limit, click on "<" to decrease the high display limit.
Current display range decides the range for the current x-axis in the graphic area. To set current displaying range,drag the handles on the display range control bar.
Select Attached Layer
If you attached a layer when creating the rule, the linked layer will be displayed.
Otherwise, the program will tell you "No data layer linked. Please set data layer".
You can attach a layer at any time by using the drop-down list. You have two options here:
1) choose one existing layer to attach.
2) choose one layer which is not in the GIS database. In this case, if the selected layer file is valid and the name of the layer is not any of these of the existing layers in GIS database, SoLIM will add the layer to GIS database, and the program will also show that the layer has already been attached with current rule. If the selected layer is valid, but there is already one layer with the same name in GIS database, the program will bring up a dialog to ask if you will replace existing layer with the new one. If you click on OK, it will replace the existing layer in the GIS Database, and the program will also show that the layer has already been attached with current rule.
If the selected layer is invalid, the program will pop up an error dialog.
Tip: A rule will take part in inference only if it is attached with a layer.
Apply the Rule to The Layer
If the rule has an attached layer, you can see the effect of applying the rule to the layer.
