Curve Fit Options

Double-click on the Curve Fit helper object to call up the Curve Fit Options dialog box. Here you can change the appearance, displayed precision, and the uncertainty.

Click the appearance button to change the text font and color as it appears in the Helper object.

Uncheck the box next to Show on Graph from the options dialog to hide the helper object from the page. Choose Reveal Hidden Objects from the Options menu -> Additional Object Options to call it back up.

If checked, the helper object will show the uncertainty on the curve fit coefficients for automatic curve fits only.  Newly created helper objects will show the current setting. That is, if it is off, all newly created curve fits will be off as well. If you check it, then any new curve fit will show the uncertainty.

Logger Pro will perform the curve fit for a selected region of the graph. Check the box next to Use Entire Range to have Logger Pro perform the curve fit on the entire column of data.
