Visualize pairs

In this example we are going to a visualize a multidimensional sample by drawing each pair of 2-d marginal clouds.

import openturns as ot
import openturns.viewer as otv

Create data to visualize

R = ot.CorrelationMatrix(3)
for i in range(1, 3):
    R[i, i - 1] = -0.4
distribution = ot.Normal([0.0] * 3, [5.0] * 3, R)
sample = distribution.getSample(200)

Create cloud pairs graphs

graph = ot.VisualTest.DrawPairs(sample)
view = otv.View(graph)

Display all graphs

otv.View.ShowAll()
