Hi,

and
PlotGradientField [ f[x,y] , {x,-2,2} , {y,-2,2} 
,ScaleFunction -> ( g[1,#1,#2] &) ]   ;

does not help ??
Regards

| Hi,
|
| I have problem about ploting vector field .
|
| Here in my inout :
|
| <<Graphics`PlotField`
|
| PlotGradientField [ f[x,y] , {x,-2,2} , {y,-2,2} 
,ScaleFunction -> (
| g[#1,#2,#3] & [1,x,y] ) ]   ;
|
| I want the scale of the vectors are denpending 
on the function g[s,x,y]
| ,  where s = 1,2,3,... ,
|
| and I transformed it to the purefunction 
g[#1,#2,#3] & [s,x,y] .
|
| But it didn't work out .
|
| Please help !!  Thank you !!
