Hello, you can simply put that dot on a transparent image background and let it turn like a hand around its “hollow” centre.
Ok, if you would still prefer to use elipse shape moving down the left bottom quadrant try this example:
insert elipse 10x10. center it. it should be positioned at x=220,y=220.
insert
0-sin(3.142/2*[BATT_PER]/100)*200 in the x coordinate tag windowand
cos(3.142/2*[BATT_PER]/100)*200 in the y coordinate tag window.explanation for possible adjustments: the 3.142/2 is the angle for one quarter of circle you want it to orbit around in radians, the [BATT_PER]/100 is the current part of travel and 200 is the radius it orbits around.
it works well in my WFS, hopefully the watch eats it too.
