matplotlib.axes.Axes.fill_betweenx

Axes.fill_betweenx(y, x1, x2=0, where=None, step=None, **kwargs)

Make filled polygons between two horizontal curves.

Create a PolyCollection filling the regions between x1 and x2 where where==True

Parameters:

y : array An N-length array of the y data x1 : array An N-length array (or scalar) of the x data x2 : array, optional An N-length array (or scalar) of the x data where : array, optional If None, default to fill between everywhere. If not None, it is a N length numpy boolean array and the fill will only happen over the regions where where==True step : {‘pre’, ‘post’, ‘mid’}, optional If not None, fill with step logic.

In addition to the above described arguments, this function can take a data keyword argument. If such a data argument is given, the following arguments are replaced by data[<arg>]: * All arguments with the following names: ‘where’, ‘x1’, ‘x2’, ‘y’.
