The curve fit section is used to plot curve fit lines on the chart.

Curve Fit: Various types of formulas can be plotted on the chart to describe the relationship between the X-tag and Y-tag. Select a formula type from the Curve Fit menu. The Polynomial, Exponent, Logarithmic, Power, and Fourier Curve Fits can use a custom number of terms.

Formula: The Formula field shows the resultant equation. The Formula and the R-Squared are shown in the Legend and Stats Grid.

To trend the formula as a calculation of the X-tag, click and drag the tag icon onto a Trend.
