How do I use the IMAQ Fit Ellipse vi?

[olsen]

I collect at set of edge-coordinates by using the "IMAQ Find circular Edge"-vi and try to use the radial points it produces to make the "IMAQ Fit Ellipse"-vi calculate a best fit ellipse. However, I don't get any results that makes sense.
I wonder what I'm doing wrong here, any suggestions?

Hi,

In the 'IMAQ Fit Ellipse.vi", depends on the border position, the "Minor Axes" is greater then the "Major Axes".

I´m using LabVIEW 6.1 and IMAQ Vision 6.0 with the update 6.0.5 discussed above.

What´s the problem? 

Thank you and sorry my poor english
