`plot`

method for class "`ITP1`

".
Plotting function creating a graphical output of the ITP for the test of the mean of one population: functional data and ITP-adjusted p-values are plotted.

The function produces a graphical output of the ITP results: the plot of the functional data and the one of the adjusted p-values.
The basis components selected as significant by the test at level `alpha1`

and `alpha2`

are highlighted in the plot of the corrected p-values and in the one of functional data (in case the test is based on a local basis, such as B-splines) by gray areas (light and dark gray, respectively).
