Visualizing 2D model data
=========================

.. sectionauthor:: Florian Zill (Helmholtz Centre for Environmental Research GmbH - UFZ)

To demonstrate the creation of filled contour plots we load a 2D THM meshseries
example. In the ``plot.setup`` we can provide a dictionary to map names
to material ids. Other plot configurations are also available, see:
:py:obj:`ogstools.plot.plot_setup.PlotSetup`. Some of these options are also
available as keyword arguments in the function call. Please see
:py:obj:`ogstools.plot.contourplots.contourf` for more information.

To read your own data as a mesh series you can do:

  mesh_series = ogs.MeshSeries("filepath/filename_pvd_or_xdmf")

the setup, this will automatically show the element edges.

Now, let's plot the temperature field (point_data) at the first timestep.
The default temperature variable from the `variables` reads the temperature
data as Kelvin and converts them to degrees Celsius.

We can also plot components of vector variables:
