   1 # This is the basic example how to draw an axis along an arbitrary
   2 # path. The function pathaxis from the graph.axis module takes a path
   3 # and returns a canvas. Different from the typical usecase in graphs,
   4 # we must fix the axis range by appropriate min and max arguments,
   5 # because of missing data. In graphs the range can be adjusted
   6 # automatically.
