GGU-PLGW: "k = f(t) function legend" menu item

If modelling was carried out in GGU-2D-TRANSIENT using soil permeabilities varying as a function of time, the k = f(t) function is displayed as a graphic image when the "Show legend" check box is activated.

In the dialog box to this menu item preferences for the visualisation can be edited (see menu item "Graphics preferences/kr = f(u) function legend").
