Hi Idyllic, Use Epilog option under the DensityPlot command. I would first build a curve graphic primitive: curve = Line[Table[{Cos[t], Sin[t]}, {t, 0, 2Pi, Pi/10}]]; And then I would draw the density plot with overlaid curve (note the GrayLevel[1] - "make it white" graphic directive): DensityPlot[Exp[-(x^2 + y^2)], {x, -2, 2}, {y, -2, 2}, PlotRange -> All, Epilog -> {GrayLevel[1], curve}] Or you could write everything above under a single procedure, function.
