![]() If the curve fit is copied into Equations window with the units information, EES will not display unit warnings. ![]() Note that if the plotted variables have units, the coefficients in the curve fit will also have units, which are included with their values. Click in the plot line color box under the Plot button to change the color of the line that will be plotted using the curve fit equation when the Plot button is clicked. The Fit button will now have changed into the Plot button and the default plot line color will appear below the button. The fitted equation will be displayed in red in the box at the bottom of the dialog window. You will have to supply guess values and (optionally) bounds for the unknown parameters.Ĭlick the Fit button (or press the Enter key). The equation you enter may be linear or nonlinear in the unknown parameters. The Enter/Edit Equation button allows you to enter any equation form or to edit a previously entered equation. The first four buttons correspond to commonly used equation forms for which linear least squares can be used to determine the unknown coefficients. A sample of the equation form will appear in blue in the box at the bottom of the dialog window. Select the form of the curve fit by clicking the appropriate radio button. You can change these values if you wish to curve fit a subset of the data. The first and last point will be displayed for the selected plot. ![]() You can edit the information in the variable names and units if you wish. The names and units used in the plot will be displayed. Note that data can be plotted from the Parametric, Lookup, Arrays, or Integral table with the New Plot or Overlay Plot commands. Chose the data to be fitted from the list of plots at the left. The Curve Fit command will find the best fit of a smooth curve through a previously plotted set of data points using unweighted least squares.
