DiscretePlot3D

DiscretePlot3D[expr,{i,imin,imax},{j,jmin,jmax}]

generates a plot of the values of expr when i runs from imin to imax and j runs from jmin to jmax.

DiscretePlot3D[expr,{i,imin,imax,di},{j,jmin,jmax,dj}]

uses steps di and dj.

DiscretePlot3D[expr,{i,{i1,i2,}},{j,{j1,j2,}}]

uses successive i values i1, i2, and j values j1, j2, .

DiscretePlot3D[{expr1,expr2,},,]

plots the values of all the expri.

Details and Options

  • DiscretePlot3D uses the standard Wolfram Language iterator specification.
  • DiscretePlot3D plots the variable i along the axis and j along the axis.
  • DiscretePlot3D treats the variables i and j as local, effectively using Block.
  • DiscretePlot3D has attribute HoldAll, and evaluates expr only after assigning specific numerical values to i and j.
  • In some cases, it may be more efficient to use Evaluate to evaluate expr symbolically before specific numerical values are assigned to i and j.
  • The precision used in evaluating expr is the minimum precision used in the iterators.
  • The form w[expr] provides a wrapper w to be applied to the resulting graphics primitives.
  • The following wrappers can be used:
  • Annotation[expr,label]provide an annotation
    Button[expr,action]define an action to execute when the element is clicked
    Callout[expr,label]label the element with a callout
    Callout[expr,label,pos]place the callout at relative position pos
    EventHandler[expr,]define a general event handler for the element
    Hyperlink[expr,uri]make the element act as a hyperlink
    Labeled[expr,label]make the data a hyperlink
    Labeled[expr,label,pos]place the label at relative position pos
    Legended[expr,label]identify the element in a legend
    PopupWindow[expr,cont]attach a popup window to the element
    StatusArea[expr,label]display in the status area when the element is moused over
    Style[expr,opts]show the element using the specified styles
    Tooltip[expr,label]attach an arbitrary tooltip to the element
  • Callout and Labeled can use the following positions pos:
  • Automaticautomatically placed labels
    Above, Below, Before, Afterpositions around the data
    xnear the data at a position x
    {s,Above},{s,Below},relative position at position s along the data
    {pos,epos}epos in label placed at relative position pos of the data
  • Labels that depend on {i,j} will be applied for each plot element, while labels that are independent of {i,j} will only occur once.
  • DiscretePlot3D has the same options as Graphics3D, with the following additions and changes:
  • AxesTruewhether to draw axes
    BoxRatios{1,1,0.4}bounding 3D box ratios
    ClippingStyleAutomatichow to draw clipped parts of surfaces
    ColorFunctionAutomatichow to determine the color of surfaces

    ExtentSizeAutomaticwidth and depth to extend from plot point
    FillingAutomaticfilling under each surface
    FillingStyleOpacity[0.5]style to use for filling
    JoinedFalsewhether to join
    LabelingFunctionAutomatichow to label points
    LabelingSizeAutomaticmaximum size of callouts and labels
    MethodAutomaticthe methods to use
    PerformanceGoal$PerformanceGoalaspects of performance to try to optimize

    PlotTheme$PlotThemeoverall theme for the plot
    RegionFunction(True&)how to determine whether a point should be included
    ScalingFunctionsNonehow to scale individual coordinates
    WorkingPrecisionMachinePrecisionthe precision used in internal computations
  • The arguments supplied to ColorFunction are , , .
  • With the setting ExtentSize->{{sxl,sxr},{syl,syr}} a horizontal plane is drawn around each plot point extending sxl to the left and sxr to the right along the axis and syl to the left and syr to the right along the axis. With ExtentMarkers->{{mxl,mxr},{myl,myr}}, the markers mxl and mxr will be used as left and right markers along the axis and myl and myr as left and right markers along the axis.
  • The arguments supplied to ExtentElementFunction are the element region {{xmin,xmax},{ymin,ymax},{zmin,zmax}} and the sample point {xi,yi,zi}.
  • With the setting ExtentSize->None, xmin is equal to xmax and ymin is equal to ymax. With the setting Filling->None, zmin is equal to zmax.
  • Possible settings for PlotMarkers include:
  • Noneomit markers when drawing surfaces
    "Point"use 2D points as markers
    "Sphere"use 3D spheres as markers
    {"Point",s},{"Sphere",s}specify the size s of the markers
    {spec1,spec2,}use specification speci for expression expri
  • The marker size s can be a symbolic value such as Tiny, Small, Medium and Large or a scaled fraction of the width of the graphic.
  • Possible settings for ScalingFunctions include:
  • szscale the z axis
    {sx,sy}scale x and y axes
    {sx,sy,sz}scale x, y and z axes
  • Each scaling function si is either a string "scale" or {g,g-1}, where g-1 is the inverse of g.
