Hi Claus - I'm afraid this isn't possible at present but we can consider this as part of any future enhancements to the route profile tool.
When using profile tool, I can change the minimum height (y axis) which can be helpfull.
However, I would also like to be able to set the max height at some fixed point (e.g. for comparison between routes with the same fixed height at y-axis)
Is that somehow posible?
Great tool by the way :-)
