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 !!
