When clicking the right mouse-button on the 2D Viewer, a small window pops up. There are three options in this window, namely "Gridlines", "Zoom", and "Properties". "Gridlines" enables the user to display vertical as well as horizontal gridlines. "Zoom" gives two options: to zoom in and to zoom out. The option "Properties" pops up a screen in which the display parameters can be set for both the "Wiggle Variable area" and the "Variable Density".
