GGU-TIME-GRAPH: "Select hydrographs" menu item

The data points for the hydrograph visualisation can be selected in the following dialog box.

The complete range of measuring points to be activated using the "All" button and deactivated using the "None" button. Individual measuring points can be switched on or off by clicking the respective check boxes. If individual measuring points are activated, as shown in the dialog box, and a second hydrograph visualisation is needed to display the previously unmarked measuring points, click the "Reverse" button.

If there are a large amount of data points you can navigate through the list using the "Forw." and "Back" buttons.
