Re: Locator appearance
You could use the DrawingTools crosshairs to select and copy points off a graph. If you want to write your own dynamic presentation, you could create your own locator by writing a Graphics statement as the second argument to the Locator statement. With your copy of Presentations you could use the CirclePointLocator statement to create a better looking and smaller locator. It is contained in the PlaneGeometry section and there is also a step-by-step tutorial on constructing custom dynamic presentations. You could display the underlying graphics and then have a point locator that simultaneously displayed computed values from its location. The WRI militaristic gun-sight locator isn't the best looking and the cross hairs don't seem to be perfectly centered anyway, so I would do away with them but in any case you can always define your own locator. One other point is that the ImageSize of the locator graphic determines the cursor "capture area" for the locator. David Park djmpark at comcast.net http://home.comcast.net/~djmpark/ From: Alexei Boulbitch [mailto:Alexei.Boulbitch at iee.lu] Dear community, I use Locator to pick up some points of the graph originated form experiment. In this case I would like to slightly modify the Locator appearance, since the gray ring on its background sometimes prevents me from seeing the point I want to pick up. I would like to leave its cross structure as it is at present, but to remove the gray ring. As an alternative, the inned (and may be, the outer) diameter of the gray ring could be increased. Do you have any idea of how to do this? Best regards, Alexei -- Alexei Boulbitch, Dr., habil. Senior Scientist IEE S.A.
