Hi
If you don't absolutely have to use Excel, I would suggest using
GeoGebra atwww.geogebra.org. Click the download button then
AppletStart. There are lots of good tutorial materials out there e.g.
Geogebra Forum:http://www.geogebra.org/forum/
Community of Geogebra users, bug reports and feature requests.
Geogebra Wiki: *http://www.geogebra.org/en/wiki/index.php/English
Collection of re-usable teaching resources.
University of Limerick:http://www.ul.ie/cemtl/resources.htm
Excellent GeoGebra step by step demos.
Math 247: * * * * * * *http://math247.pbworks.com/Learn-and-Use-GeoGebra
Fantastic Step-by-Step Help on How to Use GeoGebra by Dr Linda
Fahlberg- * * * Stojanovska. Includes accessing Geogebra properties and
methods using Javascript – * *very cool.
If it must be Excel can you send me a personal email. I have several
Word documents on creating animation using excel charts which might
help.

* * Hi,
* * does anyone know how to rotate an Isosceles triange (in the shape
of a Speedometer needle) from 0 to 100 (the speedometer dial is 240
deg in shape).
* * i am basically finding the x & y to center the Isosceles needle in
the center of the speedometer by taking the LEFT, WIDTH & TOP of the
speedometer image.
* * x=shp.Left+Shp.Width/2
* * y=shp.Top+Shp.Height/2
* * so the above would remain fixed for centering the Isosceles
triangle.

point traversing the Speedometer Arc which is 240 degrees in shape
based on a cell values ranging from 0 to 100?

Hi Paul, i have sent you a personal email. please send me a test mail
