Visualize pairsΒΆ

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

from __future__ import print_function
import openturns as ot
import openturns.viewer as viewer
from matplotlib import pylab as plt
ot.Log.Show(ot.Log.NONE)

Create data to visualize

R = ot.CorrelationMatrix(3)
for i in range(1, 3):
    R[i, i - 1] = -0.4
distribution = ot.Normal([0.] * 3, [5.] * 3, R)
sample = distribution.getSample(200)

Create cloud pairs graphs

graph = ot.Graph("Cloud pairs graph", " ", " ", True, "")
graph = ot.VisualTest.DrawPairs(sample)
view = viewer.View(graph)
plt.show()
plot visualize pairs
