Phase Plot Wrapping

Post by ulibru » Thu Jun 27, 2024 2:29 pm

A standard phase plot usually shows Y values between -P and +Pi or between -180° and +180°
Drawing such a plot with TChart results in connection lines where the phase wrapping occurs.

The connection lines appears as more or less vertical lines depending on the zooming.
What is the proper way to draw the phase without the connecting line? Is it possible?

Hello,

You could detect when the values are jumping from -180 to 180 or vice-versa and add a null point between them.
Or maybe detect when the difference between the value being currently added and the last value exceeds a threshold.
