hvplot.plotting.andrews_curves#

hvplot.plotting.andrews_curves(data, class_column, samples=200, alpha=0.5, width=600, height=300, cmap=None, colormap=None, **kwds)[source]#

Generate a plot of Andrews curves, for visualising clusters of multivariate data.

Andrews curves have the functional form:

\[f(t) = \frac{x_1}{\sqrt{2}} + x_2 \sin(t) + x_3 \cos(t) + x_4 \sin(2t) + x_5 \cos(2t) + \cdots\]

Where \(x\) coefficients correspond to the values of each dimension and \(t\) is linearly spaced between \(-\pi\) and \(+\pi\). Each row of frame then corresponds to a single curve.

Parameters:

frameDataFrame: Data to be plotted, preferably normalized to (0.0, 1.0)
class_columnstr: Column name containing class names
samplesint, optional: Number of samples to draw
alphafloat, optional: The transparency of the lines
cmap/colormapstr or colormap object: Colormap to use for groups

Returns:

objHoloViews object: The HoloViews representation of the plot.
