New Toolbar in Surface Fitting Tool

A new toolbar in Surface Fitting Tool makes it easier to discover and control plotting

options. You can use the toolbar to:

• Toggle plot mode between Rotate 3D, Data Cursor, and Exclude Outliers

• Control which plots are displayed of Surface, Residuals and Contour plots

• Control the Legend, Grid and Axis Limits

See Exploring and Customizing Plots in the Surface Fitting Tool documentation.

Usability Improvements for Surface Fitting Workflow

In Surface Fitting Tool, plot mode now defaults to Rotate 3D. A common surface fitting

workflow is to manipulate and view the surface plot from various angles. You no longer

have to select plot rotate mode initially, because it is now on by default. You can use the

toolbar to switch to data cursor or exclude outliers mode. When you turn off data cursor

or exclude outliers mode, your cursor mode is automatically set back to Rotate.

See Using Zoom, Pan, Data Cursor, and Outlier Exclusion in the Surface Fitting Tool

documentation.

The initial surface fit for polynomials is now a linear plane in x and y (poly11).

Previously the default fit was a quadratic polynomial in x and y (poly22).

If you are going to use a polynomial to fit a model, it can be helpful to start by looking at

a reference plane.

Improved Gaussian Library Model

The gaussian library model has been updated to use improved starting value defaults.

You may see different answers to previous releases because of the improved starting

values.
