Click the Show Linear vs. Non Linear button to open the Linear vs Non Linear graph dialog. This graph shows the original non-linear value for the property versus the predicted linearised value based on the fitted base plus delta values.
The menus in the graph dialog allow the base and property displayed on the graph to be changed. Where multiple bases have been defined use the left hand menu to select which base to review. To change the property displayed on the graph use the right hand side menu to select the property to review.
The base value is shown on the Linear vs Non Linear graph as a red cross.
When R2is equal to 1 the fitting is perfect and the data points lie exactly on the line. Selecting a different property in the Data Grid changes the property currently displayed in the graph.
The Linear vs Non-Linear graph is used to determine the quality of the predictions for a property. Where the predictions are accurate and linear the points will lie close to the line shown on the graph.
Tip: The properties displayed on the graphs are linked, so changing a property on one graph automatically changes the property on the other graph to the new selection.
