"""This plugin can be used to replace the stack's X data with data from
a text file, or with the MCA curve's X or Y data.

When loading from a file, the data should be in a format that can be
loaded using `numpy.loadtxt
<https://docs.scipy.org/doc/numpy-1.14.0/reference/generated/numpy.loadtxt.html>`_,
i.e. must be a CSV file without a header line and with a single column.
