The fit may take a few seconds. When it is complete the dialog box appears again, with the fit results for each parameter shown in the entry boxes. Click the Close button.
When you click Close, the program create a new page with the same name as the model, in this case, Randles. On this page are the results from the most recent Randles fit. If you were to run another Randles fit, the results would overwrite the results currently shown on the page. If, however, you were to run a different model, it too would get its own page for results.
The fit is plotted as a curve on the graph.
