The strangest thing happens when you do this. Circles that were ellipses become perfect circles.
What I do is pick one central point that looks like it could (with an ellipse shape) hit at least 2 points on the arc. Then from the SAME CENTER I increase the size of the ellipse to see if other 2 point hits occur with EXACTLY the SAME ellipse shape, (ONLY SIZE CHANGES, not shape, or aspect, or eccentricity). After I find multiple 2 point hits occur, from various ellipse SIZES, then I use AUTOscale and zoom in and out until the ellipses are close to circles...sometimes I will turn Autoscale off and NO scale LOCK...and try to make the circle shape. When they are close I use the projection tool and lay it over the key center point and size it to a large circle. I then fine tune the zoom until the circles are proper.
After all that what the "H' am I doing.
Well... when the chart is set to the correct scale for Ellipses INTO Circles...then strangely...the RIGHT Diagonals ALSO work out. Hmmm???
This is a long shot prediction. I used cloning techniques with angles, distances...and most important for this test...it was the right diagonals used to get to the final point.
I also reset the channels to match the point. They do look better now...but...I don't set the prices or the times.
So..this is only my speculative testing. If it's perfect...then I'm a genius. LOL
