Line Hough Transform Demo

The Line Hough Transform is used to detect groups of points which are positioned in straight lines in a chart.  This is an interactive demonstration showing how the transform works, building on the example supplied with the "Hough Line Transform" function as referenced in the JMP Scripting Index, making both charts clickable so that changes in one are immediately reflected in the other, and allowing the user to explore what happens to the sine waves in the Hough Transform chart when up to eight points are positioned in any desired configuration on the Points Chart.  It also includes optional annotations on both charts to allow the user to see how the four parameters (x, y, radius r and angle theta) relate to one another.
