Hi,
I have a trajectory of a vehicle (= a list of points including heading, crossfall, slope, curvature, radius, ...) and would like to visualise the crossfall. Per point there should be a line pointing left or right (transverse to driving direction) with the line having a length according to the quantity of the crossfall and pointing to left if negative, to right if positive.
I have tried font marker - an arrow to visualize heading which works well. But with the crossfall I struggle.
The font marker may be not the right joice, as it makes the lines not only longer, but also thicker.
What type of marker would right for this? Should just be a simple line that alters in length according to crossfall
How would the _expression_ look like to handle the case crossfall<0 -> heading-90; crossfall>0 -> heading+90
Any help appreciated!
TIA
Roland
