Zigzag default or self-calculated
I’ve started looking at zigzag as a chart friend, and I notice that if I leave the field blank, a number appears in the legend. It seems that is the threshold for drawing the lines. I get numbers like 9.78%. Is that a self-calculated threshold? If so, anyone know how it is calculated?

Default Parameter Values:
(none entered by default, but when the parameters box is left empty, a suitable value movement threshold will be automatically determined)

it appears to select the value from finding the smallest of the minor swings the program identifies.
