Click on "Graphs" on the Menu bar:
Click on Standard or Enhanced (more features) and a sub-menu appears::
i) Scales - this displays a Graph window displaying the rating scale or partial-credit scale summarized for all its elements.
In analysis of Lfs.txt:
ii) 1. Child (75) - Facet number 1. Facet name: Child. Count of active elements in the facet displayable here: 75
Click tp display the model and empirical curves for each element of the Child facet.
iii) 2. Activity (25) - Facet number 2. Facet name: Activity. Count of active elements in the facet displayable here: 25
Click to display the model and empirical curves for each element of the Activity facet.
Only elements with all observations on the same rating scale can be shown.
iv) DIF/Bias Graph (Enhanced only)
A. Standard. This uses the 32-bit (VB6) Winsteps graphing module.
B. Enhanced. This uses the 64-bit (Xojo) Winsteps graphing module.
You may be asked if you want to compute the empirical curves, or only display the model curves. Check "Always do the same in future", and click "Yes" unless you have very large datasets. Click on "No" if you don't need to see the empirical curves. This can be reset in Edit Initial Settings.
