Scroller Incrementation:dynamic chart working,

Hello,

I have a dynamic chart working, with the variables changing by scroller. But
I want the values to change by 0.5 each time the scroller is pressed. The
scroller doesn't seem to allow me to increment it by 0.5, any ideas how I can
do this.

regards

Wks.Range("b_inc").value = Wks.Range("b_inc").value -
SpinRight.SmallChange / 2
