Plot results on a specific path
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This example shows how to get a result mapped over a specific path
and how to plot it.

Plot path
~~~~~~~~~
Use the :class:`ansys.dpf.core.plotter.DpfPlotter` class to plot a mapped
result over a defined path of coordinates.

Plot the solution along the specified line. Note that since the line is only
moving along the y-axis, the stresses are plotted with respect to the y coordinate.
