x : 1d array of dimension N
y : 2d array (dimension MxN), or sequence of 1d arrays (each dimension 1xN)
The data is assumed to be unstacked. Each of the following
calls is legal:
stackplot(x, y) # where y is MxN
stackplot(x, y1, y2, y3, y4) # where y1, y2, y3, y4, are all 1xNm
baseline : [‘zero’ | ‘sym’ | ‘wiggle’ | ‘weighted_wiggle’]
Method used to calculate the baseline:
'zero': Constant zero baseline, i.e. a simple stacked plot.'sym': Symmetric around zero and is sometimes called
‘ThemeRiver’.'wiggle': Minimizes the sum of the squared slopes.'weighted_wiggle': Does the same but weights to account for
size of each layer. It is also called ‘Streamgraph’-layout. More
details can be found at http://leebyron.com/streamgraph/.
labels : Length N sequence of strings
Labels to assign to each data series.
colors : Length N sequence of colors
A list or tuple of colors. These will be cycled through and used to
colour the stacked areas.
