Correlation Matrix

This plot displays linear correlation coefficients, histograms and anthill plots for all selected input and output parameters and their combinations respectively, combined into one plot. A selection in this plot alters the parameter selection globally in the postprocessing.

Settings

Option	Description
Common Settings
Histogram classes	Sets the value for the number of bars displayed in histograms when View as is not All correlations.
View as	Select one of the following options: All correlations—View only correlation tiles Correlations vs. Anthills—View correlations in upper left area, histograms on main diagonal and anthills in lower right area Anthills vs. Correlations— View correlations in lower right left area, histograms on main diagonal and anthills in upper left area All Anthills—View Histograms on main diagonal, all other points view Anthills
Ranges	Select one of the following options: All—Total matrix In-In—Parameter range at x-axis and y-axis In-Out—Parameter range at x-axis and Responses + Criteria range at y-axis Out-In—Range Responses + Criteria range at x-axis and Parameter at y-axis Out-Out—Range Responses + Criteria range at x-axis and Responses + Criteria range at y-axis

Python Scripting

Create Visual

Creates a Correlation Matrix using data with data_id.

    ext_corr = Visuals.ExtendedCorrelationMatrix(
        Id("Extended Correlation Matrix"),
        data_id
    )

Add to Postprocessing

Adds Correlation Matrix in postprocessing to control_container, using the specified relative positioning.

    control_container.add_control (
        ext_corr,
        True,
        RELATIVE_POSITIONING,
        0, 70/100., 1/2., 30/100.
    )
