Now you can click the item representing the variable you wish to be shown in the Graphic trigger window.A dialog box appears listing all the currently existing instances of debug windows, and asking you which one is to receive the object you have just clicked.
In order to plot the curve of variable b, select Graphic trace in the Debug windows column, then click OK. The name of the variable is now printed in the Track column.
The same procedure applies to all the variables you wish to inspect.Once you have added to the Graphic watch window all the variables you want to observe, you can click Edit>Insert/Move mode, so as to restore the original shape of the cursor.Once the first variable is dropped into a graphic trace, the Graphic properties window is automatically shown and allows the user to setup sampling and visualization properties.
