GGU-PLGW: "Define hydrograph points" menu item

By clicking selected node points with the left mouse button the program will evaluate the temporal development of one of the flow variables for these points. After closing the info box you are first asked which flow variable should be displayed for these points. You will see the following dialog box for a vertical-plane system, for example.

If you want to evaluate flow variables as hydrographs for further nodes, click the "Keep current nodes" option button before closing the dialog box. After clicking "Define new nodes" the existing nodes are deleted from the list.

You can label the nodes instead of the automatically assigned node numbers. The number of characters is limited to 8 characters.
