[OpenLayers-Users] Using OpenLayers for interactive plotting

[eider at fh-bingen.de]

Hi Bobby,

from mypoint of view, it could be possible to abuse OL as a viewer for  
your mathematical plots.

You just have to create a new layer, whose points are calculated based  
on a mathematical function.
But here arise my problems:
Coordinates are from my point of view discrete values. Your  
math-function is non discret.
So your layer could calculate its values based on the x-coordinates of  
your actual window, where each y-value would be connect by a line.
When zooming in each line would first show an interpolation of the  
values between the y-values of 2 x-coordinates, but you should do a  
recalculating.
But it could work.

You sould think about the location of your calculating process:
client-side within javascript or server-side with ?????


For drawing the background lines and units of your coordinate-system you
can use a image layer


Cheers Carsten
