# Large data -list contour plot -list log plot

I've a large data make matrix 100*100 and and other two sets of data represent the x and y axis. Each value in the matrix is a related to one value in x and one value of y. I ask about a way to plot these data list contour plot and about how to combine this figure with list log plot and I don't want to write the the data manually

mat = {{22, 36, 44, 44, 48, 59, 67, 87, 89, 83}, {44, 32, 39, 52, 54,
72, 63, 78, 118, 139}, {41, 36, 56, 63, 77, 84, 78, 107, 112,
141}, {41, 64, 50, 82, 106, 100, 113, 127, 156, 183}, {61, 60, 57,
85, 95, 122, 134, 145, 172, 197}, {50, 61, 78, 106, 113, 151, 155,
185, 202, 238}, {61, 78, 116, 150, 122, 164, 207, 215, 227,
265}, {95, 100, 108, 155, 147, 192, 217, 255, 267, 364}, {71, 144,
128, 152, 187, 227, 241, 314, 302, 363}, {126, 166, 213, 214, 290,
284, 304, 378, 392, 420}} ;
x = {0.01, 3, 7, 10, 13, 17, 18, 20, 23, 30} ;
y = {0.01, 0.19, 2, 4, 5, 8.5, 9, 10, 11, 13};

• ListContourPlot accepts matrix data, and adding DataRange -> {{xmin, xmax}, {ymin, ymax}} will ensure the ticks are displayed correctly. I do not know what you mean by combining this with ListLogPlot, though. Would you clarify, please. Jun 29, 2015 at 15:39
• I want to combine two figures one plotted using list contour plot and other figure by list log plot in the same figure like the order show but show order does not work with me Jun 29, 2015 at 15:43
• It would be easier to understand your question and to provide some help, if you could provide a minimal example of working and nonworking code together with a picture or description of the desired output. A smaller matrix (10x10) or a random matrix should reproduce the problem. Jun 29, 2015 at 15:51
• mat={ {22, 36, 44, 44, 48, 59, 67, 87, 89, 83}, {44, 32, 39, 52, 54, 72, 63, 78, 118, 139}, {41, 36, 56, 63, 77, 84, 78, 107, 112, 141}, {41, 64, 50, 82, 106, 100, 113, 127, 156, 183}, {61, 60, 57, 85, 95, 122, 134, 145, 172, 197}, {50, 61, 78, 106, 113, 151, 155, 185, 202, 238}, {61, 78, 116, 150, 122, 164, 207, 215, 227, 265}, {95, 100, 108, 155, 147, 192, 217, 255, 267, 364}, {71, 144, 128, 152, 187, 227, 241, 314, 302, 363}, {126, 166, 213, 214, 290, 284, 304, 378, 392, 420} } x={0.01, 3, 7, 10, 13, 17, 18 ,20, 23, 30} y={0.01,0.19, 2, 4,5, 8.5,9,10,11,13} Jun 29, 2015 at 15:56
• It means for x=0.01, 0.01 the matrix value 126 and for x=0.01, y=0.19 matrix value 71 and etc. Jun 29, 2015 at 16:00

I don't understand the "combining" part of your question, but this makes a contour plot:

ListContourPlot[Flatten /@ Flatten[Transpose[{Outer[List, x, y], mat}, {3, 2, 1}], 1],
Epilog -> {Red, PointSize[Medium], Point /@ Outer[List, x, y]}]]


ContourPlot[
Interpolation[Flatten[Transpose[{Outer[List, x, y], mat}, {3, 2, 1}], 1]][u, v],
Evaluate@{u, Sequence @@ ({Min@#, Max@#} &[x])},
Evaluate@{v, Sequence @@ ({Min@#, Max@#} &[y])}]
