 All predefined Fit Curves are listed in this table. You also can specify [[custom_fit_equation|custom fit equation]]. Unlike custom fit equations these curves can be adjusted with mouse on Fit Plot. All predefined Fit Curves are listed in this table. You also can specify [[custom_fit_equation|custom fit equation]].
