Learn how, Wolfram Natural Language Understanding System, cyclically use successive directives for successive regions. My variables are distances (48 values) and angles(15 values) and my energy data is a 2d matrix of 48 x 15 values. To plot all of values of f in the interval (if Mathematica fails to): PlotRange -> All To increase the number of sampled plot points used to 50: PlotPoints -> 50 For labels on x-axis and y-axis: AxesLabel -> {"x", "f"} as 2D contour plots in Mathematica, their graph lines were converted to paths, and then the plots were exported as .svg files. I would also define my color style and use it like this: Clear[contours] Richard's suggestion is a nice suggestion. Here is another take by creating your own color function that makes use of "GrayTones". myColorFunc[x_]... Set the colors for the filled contour plot by changing the colormap. Updated in 1999 (4.0) contour diagram A stereographic equal-area net on which orientation data (i.e. the azimuths of structural features) are plotted as lines or points and then joined to form contours linking areas of equal density of data, thus providing a visual description of the range and concentration of the data.

A, B and C in your example, post #1, are not contour plots but show single contours. Except as noted, function signatures and return values are the same for both versions. You can create a contour plot with emphasis on selected contour lines by splitting the data and creating two overlapping contour plots. Try wrapping Rasterize[....] around the result or around the commmand producing the plot. It gives a nice 3 d contour with color shading, but no legend that says what. ContourPlot by default generates colorized grayscale output, in which larger values are shown lighter. Technology-enabling science of the computational universe. This book presents the basic concepts of continuum mechanics. That is, of course, not a ContourPlot. A contour plot has many contours labeled by numbers as, say isobars on a weather map or different colors as you described in post #3 for values of quantity Q.

Wolfram Natural Language Understanding System. Here is a command that generates a temp vs x and y. I think you can just include this in the options: ColorFunction -> (ColorData[{"ThermometerColors", {0.55, 0.85}}]), ColorFunctionScaling -> False Software engine implementing the Wolfram Language. Technology-enabling science of the computational universe. Software engine implementing the Wolfram Language. More points are sampled where the function changes quickly: The plot range is selected automatically: Areas where the function becomes nonreal are excluded: The surface is split when there are discontinuities in the function: Use PlotPoints and MaxRecursion to control adaptive sampling: Use PlotRange to focus in on areas of interest: Use Exclusions to remove curves or split the resulting surface: Use RegionFunction to restrict the surface to a region given by inequalities: The domain may be specified by a MeshRegion: Show multiple implicit curves, with styles chosen automatically: Use a theme with emphasized contour style, simple ticks, and a legend: Use a theme with simple ticks and legends in a bold color scheme: Use an Automatic setting to get the natural ratio: Use a black boundary around the edges of the surface: Use a red boundary around the edges of the surface: Use a thick red boundary around the edges of the surface: BoundaryStyle applies to holes cut by RegionFunction: BoundaryStyle does not apply to cuts made by Exclusions: Show clipped regions like the rest of the surface: Use light red where the surface is clipped above and pink below: Named color gradients color in the direction: Color with blue if contour values are negative, and with red otherwise: ContourLines is superseded by ContourStyle: Use at most 5 automatically selected contours: Use specific contours with specific styles: Use a function to generate a set of contours: Have contours at the 10% and 90% percentile values: The automatic shading is darker at low values and lighter at high values: Shade between contours using a color function: Use an explicit list of colors between contours: The default contour style is a partially transparent line: Alternate between red and dashed contour lines: Use different styles for different equations: Use dashed red lines for all the equations: Show where ContourPlot samples a function: This uses automatic methods to compute exclusions: Indicate that no exclusions should be computed: Use a condition with the exclusion equation: Use both automatically computed and explicit exclusions: Use a red line to indicate the exclusion set: Draw frames on the bottom and the left edges only: Use the independent variables as frame labels: Refine the surface where it changes quickly: Show the initial and final sampling meshes: Use mesh levels corresponding to fixed distances from the origin: Use red mesh lines in the direction and thick mesh lines in the direction: PlotLegends automatically matches the color function: PlotLegends->Automatic labels implicit curves with placeholder values: Use PlotLegends->"Expressions" to use the actual equations: Use Placed to change the legend position: Use BarLegend to change the legend appearance: Emphasize performance, possibly at the cost of quality: Use more initial points to get smoother contours: Use an explicit range to emphasize features: Use a theme with simple ticks and a legend: Use any logical combination of conditions: Limit an elliptic curve to the unit disk: By default, plots have linear scales in each direction: Use a linear scale in the direction that shows smaller numbers at the top: Use a reciprocal scale in the direction: Use different scales in the and directions: Reverse the axis without changing the axis: Use a scale defined by a function and its inverse: Positions in Ticks and GridLines are automatically scaled: Evaluate functions using machine-precision arithmetic: Evaluate functions using arbitrary-precision arithmetic: Plot a sum of 5 sine waves in random directions: Find the minimum of a function in a region: An electrostatic potential built from a collection of point charges at positions : Charge colors, using green for negative and orange for positive: ContourPlot samples more points where it needs to: Use Plot3D and DensityPlot for surfaces and densities: Use ParametricPlot for plane parametric curves and regions: Use ContourPlot3D and RegionPlot3D for implicit surfaces and regions: Automatically avoid jumps that are detected as zero crossings: Contours for functions where are always poorly detected: Giving a value in between allows for easy contouring: A polynomial with zeros at the lattice points : DensityPlot  ListContourPlot  RegionPlot  Plot3D  ContourPlot3D  SliceContourPlot3D  StreamPlot  StreamDensityPlot  MeshFunctions  ContourLabels  ContourShading  GeoGraphics, Introduced in 1988 (1.0) Appear ( by accident, but no legend that says what changing the colormap in.
