I have problem because of the max point and min point, when I have too high or low data point, it just make it white.
Here is example of data
Data = Table[
1/Sqrt[x^2 + y^2] + Cos[x*y] -
1/Sqrt[(x - 0.5)^2 + (y - 0.5)^2], {x, -3.01, 3, 0.1}, {y, -3.01,
3, 0.1}];
and I listplot this
ListContourPlot[Data, ContourLabels -> False, Contours -> 20,
ColorFunction -> "BlueGreenYellow"]
and I got
I do not like this graph because the white area does not tell me it is max or min, so I adjust the code to fix the max and min as the certain color
Needs["PlotLegends`"]
plTest = ListContourPlot[Data,
Contours -> {-5, -2.5, -1, -0.5, -0.25, 0, 0.25, 0.5, 1, 5},
ImageSize -> 720, ColorFunction -> "BlueGreenYellow",
PlotRange -> {{0, 60}, {0, 60}, All}];
ShowLegend[plTest, {ColorData["BlueGreenYellow"][1 - #1] &, 30, "max",
"min", LegendPosition -> {0.7, 0.15},
BaseStyle -> {FontSize -> 14}}]
and I got
but Now I cannot see all the interesting things in the interval that all the small values are in.
Is there any way that I can fix the color of certain interval that max and min points are in and plot contour on just certain range?
