Phase plots


To show the phase plot press the Phase diagram button in the Fit module. By default the first found inactive frequency is being used for the plot. If no inactive frequency can be found a default frequency value of 1.0 is chosen.

Please note:
This option is not available in the periodic time shift mode.

    The frequency combo-box
    Defines the frequency that is used for the plot. The combo-box contains all inactive frequencies that have been found in the Fit module. To use a user-defined frequency value select "Other Frequency" and type the frequency into the input field next to the combo box.

    Use binning
    If this option is selected the data will be averaged for discrete phase ranges. The input field next to the check-box defines the number of bins.

    Zero point (time)
    By default the program calculates the phases with respect to a zero point at time 0.0. To define an other zero point, enter a new time in the zero point input field and press the Return key.
