What's new in version 3.1.9.7
Changed the behavior of the "X-Y plot for a range of values" which allowed plotting graphs after changing input parameters in the main window without hitting the "Calculate" button which, however, is required to update the "X-Y plot for a range of values" with the new input parameters from the main dialog.
