Hi group, Please consider the example below to illustrate my question (the original problem is somehow much more complicated): t1 = Table[Sin[3 x*y], {x, -3, 3, .1}, {y, -3, 3, .1}]; t2 = Table[If[x*y < 0, Sin[3 x*y]], {x, -3, 3, .1}, {y, -3, 3, .1}]; p1 = ListContourPlot[t1, Contours -> {0}, ContourShading -> False, DataRange -> {{-3, 3}, {-3, 3}}, ContourStyle -> Black]; p2 = ListContourPlot[t2, Contours -> {0}, ContourShading -> False, DataRange -> {{-3, 3}, {-3, 3}}, ContourStyle -> {Red, Dashed, Thick}]; Show[p1, p2] Is there a way to show only the results of the intersection of these two contour plots? Thank you Luiz
