Creating a Group Characteristic Line/Map

Create a distribution.
If your model contains no distribution, you cannot create a group characteristic line/map.
In the combo box of the Elements palette or with the arrow buttons in the toolbar, select the table type Group.
Click the OneD Table or TwoD Table button.
The Properties editor opens. Since all characteristic lines/maps are created as parameters, the non-volatile attribute is set and the option is disabled.
In the Interpolation combo box, select an interpolation routine for the characteristic line/map.
By default, the combo box contains two interpolation routines, Linear and Rounded. More are added when you use user-defined interpolation routines.
Adjust the other element properties according to your needs and click OK.
The Distribution for dialog window opens.
From the X-Distribution and Y-Distribution combo boxes, select suitable distributions.
The Y-Distribution combo box is only available for group characteristic maps.
Click OK.
When you click Cancel, no distribution is selected. The table is created nonetheless, but it is labeled 'undef'. You have to select the distribution(s) via the Edit menu, Distribution menu option, prior to using the table.
Place the element in the drawing area.
