[BUG-6406] XY chart absolute legend stuck in default position

I was tring to move the legend to the middle of the chart using the absolute position propery, but any value of x and y I put in results in no change in the actual position of the legend…
Is it a bug?

Doesnt seem to do anything yeah,
I think you should stick to the predefined positions anyways tho
