Workspace Node: 2D Normal Probability Plots - Quick Tab
The 2D Normal Probability Plots workspace node can be accessed from the Feature Finder, ribbon bar, or Node Browser. The Quick tab of the specifications dialog box is displayed by default when you double-click the node.
Variables
Click this button to display a variable selection dialog box, in which you select the variable(s) to be plotted. If you select more than one variable, a sequence of graphs (one for each variable selected) will be produced. The selections made will be displayed below the Variables button.
Graph type
Select the type of probability plot to be plotted from the Graph type list. Click the desired plot link below for a brief description of that type of graph.
Normal
Detrended
Half-Normal
Multiple plots in one graph
When you have chosen more than one variable to be plotted, select this check box to create an overlaid probability plot. When this check box is selected, several probability plots will be displayed in the graph: one for each selected variable. A different point marker and color is used for each of the multiple variables and referenced in the legend so that individual plots representing different variables can be discriminated in the graph. When this check box is cleared, separate graphs will be generated for each variable.
Statistics
You can include statistics as footnotes in the graph by selecting the check box in this group box.
Shapiro-Wilk
Select this check box to include the Shapiro-Wilk W statistic for normality and its associated p-value.
Do not assign average ranks to tied observations
This check box is selected by default, which enables you to see all data points, even the ties. When this check box is cleared, the "tied" points will overlap.
