Abstract: A computer-executed method for editing a numeric chart includes displaying a numeric chart having at least one object with a dimension representing a variable and positioning a cursor in the object. A numeric value of the variable is displayed near the object in response to positioning the cursor in the object. In response to receiving a command to change the value of the variable, the displayed value and the dimension are changed to correspond to the changed value. The chart may be edited by moving an element of the object with a cursor and presenting a readout of the value of the variable at or near the location of the cursor. The chart may be edited by changing a location of an element of the object in response to entry of a value in an entry field that is at least partly within the object.

Abstract: A computer-implemented warranty knowledge base construction system and method. An user interface receives a first rule related to vehicle repair claim processing. A rules syntax data store stores syntax rules for constructing repair claim-related rules. A knowledge base generator module connected to the user interface and to the rules syntax data store determines whether the first rule is in an acceptable syntax based upon the stored syntax rules. The first rule is used in a knowledge base system to process repair claims.

Abstract: Editing of a computer- or processor-generated graphics chart is enhanced by automatic movement of shapes and editing of lines in the chart when shapes are added to or deleted from the chart in response to user-entered commands.
