I see the problem but don't know what causes it. If it happens consistently,
you could correct for it using the IncrementLeft method. You can add code
like this after the End With line for any of the segments:

myArc.Select
Selection.ShapeRange.IncrementLeft -0.5

-0.5 means to move half a point to the left. Positive numbers will move it
to the right. I got the best results with your example by moving the first
segment to the right 0.5, the second segment to the left 0.5, and the third
segment to the right 0.2 points. Hopefully one of the MVPs can give us both a
real explanation and solution, not just my clumsy workaround.

Hope this helps,

Hi,

I'm trying to create a dial-type control for an Excel-based report. The
shape I'm after is basically the top half of a pie chart, and I'll add
numbers, needles etc.

I'm using msoShapeArc to create specific zones for the dial e.g.
green-amber-red, which will be a 0-100% scale. It's almost working, but using
the .Adjustment(1) and (2) settings to set the angles is shifting the arcs
out of line, and I can't figure out why! The code is below - any help greatly
appreciated.

To see the problem exaggerated, repeat the line ".Adjustments(1) = 144" in
the second segment and watch the arc shift right each time. For some reason
it's not all of the arcs, just the some (the 2nd in this axample).

Thanks,

Pat.
