2D Scatterplot - Polynomial Fit,  95% Confidence Interval

This graph option will produce a scatterplot with a polynomial fit (by default, of the 5th degree) to the data and a 95% confidence interval for that line.  Once created the probability value for the confidence interval can be changed in the Regression Bands dialog accessible by right-clicking on a regression band and selecting Properties from the shortcut menu.  The order of the fitted polynomial function can be changed in the Fitting dialog accessible by right-clicking on the fitted line and selecting Properties from the shortcut menu.  Note that both of these dialogs are also available as tabs on the Plot Layout dialog.

This option is available via Graphs of Input Data (see Scatterplot By...) and via the Graphs of Block Data custom graph options (e.g., Custom Graphs for Entire Column).  Scatterplots can also be created with a greater variety of fitted functions and confidence levels using the Graphs options from the Graphs menu, see Graphs menu graphs, 2D Scatterplots, and 3D Scatterplots.
