Hi Katharina,

You're right that ProfilePlot currently doesn't have an "easy" way to set
the plot axes labels. Adding such a feature would be a reasonable thing to
do as well as an easy first yt project if you're interested. If you're not
interested, please feel free to file an issue with the feature request:

https://bitbucket.org/yt_analysis/yt/issues/new

As a workaround, you can access the matplotlib axes object and customize
the plot from there using that interface. Here is a snippet that
illustrates how to do this:

    plot = yt.ProfilePlot(ds.all_data(), ('gas', 'density'), ('gas',
'temperature'))
    ax = plot.axes[('gas', 'temperature')]
    ax.set_ylabel('my ylabel')
    plot.save()

Note that the keys of the plot.axes dictionary are the full field tuples,
not the field name of the field plotted along the y axis. It's a dictionary
because you are allowed to pass more than one y field to ProfilePlot, which
will make more than one plot. You might take a look at plot.axes.keys() to
see what I mean.

Hope that helps,

Nathan
