CALLS
region(hfig,Color)
hfig: Vector of handles to the SOM planes
Color: String with a color code
Description
REGION allows the user to highlight regions by clicking points with the mouse
on any of the SOM maps. The polygon line enclosing a region will be
drawn for all the SOM maps regardless where the points have been
clicked. Points can even be clicked on planes from other different
figure since the 2D coordinates in V are the only information needed.
