LV_METER arc reverse mode (draw counter clockwise)

How-to

Description

As title states - can I set the LV_METER arc to draw reverse? I would like to draw counter clockwise like an arc object has REVERSE mode - is it possible?
Or can this only be done with an ARC object?

What LVGL version are you using?

v8.3

I’ve had the same problem and managed to solve it by using the meter object for drawing ticks and using the arc object for drawing the arc. Just make sure you add the meter object after the arc in order have a proper drawing. However, this will work only if you don’t intend on using a dial indicator.

Yep I eventually did that.
I have a gauge with positive and negative ranges and a fine red needle. The arc is active on the positive range and follows the needle:

I never implemented the reverse arc part of it, but might add it in the future when it gets pushed up the priority list to tasks
