PlotDesign

PlotDesign(design, bounds, Nx, Ny, figure=None, axes=[], plot_kwargs={}, axes_kwargs={}, text_kwargs={})

Plot a design using a scatter plot approach (plots 2D marginals).

In addition, the function plots a grid, i.e. horizontal and vertical lines to distinguish LHS character

Parameters

design2-d sequence of float

Design

bounds: :class:`openturns.Interval`

Bounds of the underlying distribution

nxdivint

Number of subdivisions in the X axis

nydivint

Number of subdivisions in the Y axis

Returns

figmatplotlib figure

Figure representing the LHS

Examples

>>> import openturns as ot
>>> from openturns.viewer import PlotDesign
>>> # Bounds are [0,1]^5
>>> # Size of sample
>>> size = 10
>>> # Factory: lhs generates (here centered)
>>> distribution = ot.ComposedDistribution([ot.Uniform(0.0, 1.0)]*5)
>>> bounds = distribution.getRange()
>>> lhs = ot.LHSExperiment(distribution, size)
>>> lhs.setRandomShift(False) # centered
>>> lhs.setAlwaysShuffle(True) # randomized
>>> # Generate a design
>>> design = lhs.generate()
>>> # Plot the design
>>> fig = PlotDesign(design, bounds, 10, 10)
