Hi, > (* save the Mathematica graphics commands *) > VFPgrapfixCommands = VectorFieldPlot[{Sin[x], Cos[y]}, {x, 0, 2 \ > [Pi]}, {y, 0, 2 \[Pi]}]; > > - look inside the commands..lo and behold they contain the stuff you > are looking for > > (* look at them *) ?VFPgrapfixCommands > > - these dumps give you the primitives you are looking for > > VFPgrapfixCommands[[1, 2]] > VFPgrapfixCommands[[1, 2]] > adding to this helpful advice I want to mention that, when remembering that graphics are just ordinary mathematica expressions, you can scale all arrow heads by a common factor with a simple replacement like this: VectorFieldPlot[{Sin[x], Cos[y]}, {x, 0, 2 Pi}, {y, 0, 2 \[Pi]}] /. Arrowheads[x__] :> Arrowheads[0.75*x] hth, albert
