ListDensityPlot

ListDensityPlot[array]
generates a smooth density plot from an array of values.
ListDensityPlot
generates a density plot with values defined at specified points.
  • ListDensityPlot[array] arranges successive rows of array up the page, and successive columns across.
  • ListDensityPlot linearly interpolates values so as to give smooth shading.
  • ListDensityPlot is mainly intended for discrete samplings of continuous data; ArrayPlot is intended for purely discrete data.
  • ListDensityPlot by default generates output in which larger values are shown lighter.

  • array should be a rectangular array of real numbers; holes will be left in the plot whenever there are elements that are not real numbers.
  • ListDensityPlot[array] by default takes the x and y coordinate values for each data point to be successive integers starting at 1.
  • The setting DataRange specifies other ranges of coordinate values to use.
  • ColorFunction is supplied with a single argument, given by default by the scaled value of f.
  • The setting for VertexColors must be an array or list with the same structure as the array or list of values.
Use an array of values to define heights for a density:
Give explicit , , coordinates for points in a density:
A larger set of , , samples:

For regular data consisting of values, the and data ranges are taken to be integer values:
Provide explicit and data ranges by using DataRange:
For irregular data consisting of , , triples, the and data ranges are inferred from data:
Areas around where the data is nonreal are excluded:
Use MaxPlotPoints to limit the number of points used:
PlotRange is selected automatically:
Use PlotRange to focus in on areas of interest:
Use RegionFunction to restrict the density to a region given by inequalities:
Add labels:
Color the density by height:
Provide overlay meshes:
Provide an interactive Tooltip for the density:
No boundary is used by default:
Use a red boundary around the edges of the surface:
BoundaryStyle applies to holes cut by RegionFunction:
BoundaryStyle applies where there are jumps in the surface:
Clipped regions are not shown by default:
Color clipped regions like the rest of the density:
Use pink to fill the clipped regions:
Use light red where the surface is clipped above and pink below:
Color by scaled coordinate:
Specify graylevel intensity by scaled coordinate:
Named color gradients color in the direction:
Use brightness to correspond to the height or density of a function:
Use the interpolation between two colors to indicate the height or density of a function:
Get the natural range of values by setting ColorFunctionScaling to False:
Arrays of height values are displayed against the number of elements in each direction:
Rescale to the sampling space:
Triples are interpreted as , , coordinates:

The dataset is normally interpreted as a list of , , triples:
Densities are normally blended across polygons:
Use zero-order or piecewise constant interpolation:
Use third-order spline interpolation to fit the data:
Interpolation order 0 to 5:
For irregular data, zero-order interpolation gives Voronoi regions for each point:
ListDensityPlot normally uses all the points in the dataset:
Limit the number of points used in each direction:
MaxPlotPoints imposes a regular grid on irregular data:
The grid does not extend beyond the convex hull of the original data:
No mesh is used by default:
Show the initial and final sampling mesh:
The entire mesh for irregular data is a Delaunay triangulation:
Use 5 mesh lines in each direction:
Use 3 mesh lines in the direction and 6 mesh lines in the direction:
Use mesh lines at specific values:
Use different styles for different mesh lines:
Use the value as the mesh function, giving a continuously colored contour plot:
Use mesh lines in the and directions:
Show where the real and imaginary parts of a function are constant over the complex plane:
Mesh lines are partially transparent by default:
Use red mesh lines:
Use red mesh lines in the direction and dashed mesh lines in the direction:
Generate a higher-quality plot:
Emphasize performance, possibly at the cost of quality:
Automatically compute the range and clip extreme portions of it:
Use all points to compute the range:
Plot over a region in :
The region depends on DataRange:
Regions do not have to be connected:
Use any logical combination of conditions:
ListDensityPlot usually colors the density using a color function:
Specify random colors for each vertex:
Plot a probability density function of two variables:
Compare to the empirical density function:
Show the regions closest to a set of points:

ListDensityPlot is similar to ListPlot3D viewed from above:
ListDensityPlot and ListPlot3D view as a function of and :
The data has only one value for each , pair:
The data has two values for each , pair:
ListDensityPlot associates colors with the vertices of polygons:
Raster, ArrayPlot, MatrixPlot, and ReliefPlot associate colors with the whole polygon:
Use ArrayPlot for arrays of discrete data:
Use MatrixPlot for structural plots of matrices:
Use ReliefPlot for matrices corresponding to medical and geographic values:
Use DensityPlot for functions:

Use DateListPlot to show data over time:
Use ParametricPlot3D for three-dimensional parametric curves and surfaces:
The appearance may depend on the source of the data:
An matrix is by default interpreted as a list of triples:
Use DataRange->All to force interpretation as a matrix of values:
