Can I fit multiple data sets using the Basic Fitting Tool in MATLAB?

After plotting multiple data sets in a MATLAB figure window, selecting "Tools > Basic Fitting", and using the "Select data" menu to select a data set, I can fit an equation to the selected data.
When I select a different data set, however, the previous fit is erased.
How can I view fits to more than one data set in the same figure window?

The ability to fit multiple data sets is not available in the Basic Fitting Tool.
There are several workarounds:
1. Use the "Numerical results" panel of the Basic Fitting Tool to save each fit to the workspace, then plot the data sets and the fits to the same figure window using the HOLD command.
2. Use the MATLAB backslash operator (\) to produce the fits and the plots from a MATLAB script.
3. Use the Curve Fitting Toolbox.
