DrawPairsXY(sampleX, sampleY)¶

Draw 2-d projections between marginals of two samples.

Parameters:

sampleX2-d sequence of float: First sample.
sampleY2-d sequence of float: Second sample. It must have the same size as the first sample.

Returns:

graphGridLayout: The graph object

Notes

This method allows one to draw the relationships between the margins of two samples. This consists of a collection of 2-d projections of the marginals of sampleY (in lines) with respect to the marginals of sampleX (in columns). The point style is given by the ‘Drawable-DefaultPointStyle’ key in the ResourceMap. The color is given by the first individual color in the default palette.

Examples

>>> import openturns as ot
>>> from openturns.viewer import View
>>> ot.RandomGenerator.SetSeed(0)
>>> dim = 3
>>> R = ot.CorrelationMatrix(dim)
>>> R[0, 1] = 0.8
>>> distribution = ot.Normal([3.0] * dim, [2.0]* dim, R)
>>> size = 100
>>> sampleX = distribution.getSample(size)
>>> sampleY = distribution.getSample(size)
>>> clouds = ot.VisualTest.DrawPairsXY(sampleX, sampleY)
>>> View(clouds).show()
