Hi, have you tryed to use x in [-2,2] and y in [-2,2] ?? Regards Jens "Vladislav" <kazimir04 at yahoo.co.uk> schrieb im Newsbeitrag news:deeo93$38f$1 at smc.vnet.net... | Hello, | | I try two commands, the only difference being .9 in lieu of .5 in the | Contours option. | | ContourPlot[Exp[-(x^2 + | y^2)/2], {x, -1, 1}, {y, -1, 1}, | Contours -> {.39, .5, .95}, | ColorFunction -> ( | GrayLevel[#1] &), PlotPoints -> 100]; | | ContourPlot[Exp[-(x^2 + | y^2)/2], {x, -1, 1}, {y, -1, 1}, | Contours -> {.39, .9, .95}, | ColorFunction -> (GrayLevel[#1] &), | PlotPoints -> 100]; | | | I obtain two different plots. The smallest circle is the same for the | two pictures, it is OK becouse it corresponds to the Contor at 0.95. | | I expected to have 3 circle on the two pictures with the only | difference in the second circle at .9 or .5. In reallity, I have only | two circles in the first plot and three circles in the second one. | Moreover the external contour at .39 is not the same in the two | pictures. | | Can anybody explain or justify this behavoir? | | Vlad |
