Three graphs are displayed.

Vertical Alignment

The top graph displays the vertical alignment plus selected ground lines and annotations.

Road width Pane

The middle graph represents the road widths.

It's X-axis represents chainage values in metres, while it's Y-axis represents widths in metres. Apart from the graphical editing functions documented below, there are also a number of shortcut keys that can be used to manipulate the view or to edit the alignment.

Superelevation Pane

The lowest graph represents the superelevation data.

It's X-axis represents chainage values in meters while it's Y-axis represents superelevation rates in percentage. The horizontal alignment will be indicated by a line at Zero superelevation. Horizontal curves will be indicated by thick lines, while transition curves will be indicated as gaps in the line.
