Use the PerformanceGoal option. Manipulate[ ContourPlot[ a x^2 + 2 b x y + c y^2 + 2 d x + 2 f y + g == 0 /. {a -> 1, c -> 3, d -> 0, f -> 0, g -> -1} // Evaluate, {x, -5, 5}, {y, -5, 5}, PerformanceGoal -> "Quality", PlotPoints -> 10], {{b, 0}, -5, 5}] David Park djmpark at comcast.net http://home.comcast.net/~djmpark/ From: van der Burgt, Maarten [mailto:Maarten.VanDerBurgt at icos.be] Dear all, The following produces a smooth function. But when I hold and move the slider the function appears jagged and is only fully drawn when I release the slider. I know this is done to show an initial result very fast. Is there a method to influence this behavior? Manipulate[ ContourPlot[ a x^2 + 2 b x y + c y^2 + 2 d x + 2 f y + g == 0 /. {a -> 1, c -> 3, d -> 0, f -> 0, g -> -1} // Evaluate, {x, -5, 5}, {y, -5, 5}, PlotPoints -> 10], {{b, 0}, -5, 5}] Thanks for your help, Maarten
