PointValuePlot

PointValuePlot[{pt1val1,pt2val2,}]

plots the points pti styled according to the values vali.

PointValuePlot[ptsvals]

uses a collection of points pti from pts with corresponding values vali from val.

PointValuePlot[,enc]

uses the visual encoding enc to represent the values vali in the plot.

PointValuePlot[data,]

plots the locations and values from data.

Details and Options

  • PointValuePlot uses various visual encodings enc such as color, size and shape to represent values at specific locations.
  • The coordinates {x,y} in point pti can be given in the following forms:
  • xia real-valued number
    Quantity[xi,unit]a quantity with a unit
    Around[xi,ei]value xi with uncertainty ei
    Interval[{xmin,xmax}]values between xmin and xmax
  • The ptsi can be geographic locations with the following forms:
  • GeoPosition[{lat,lon}]latitude and longitude
    Entity[]geographic entity
    Dated[]dated entity
  • Multiple points pts can be given in the following forms:
  • {pt1,pt2,}list of individual points
    QuantityArray[]array of quantities

    Style[e,opts]show the element using the specified styles
    Tooltip[e,label]attach an arbitrary tooltip to the element
  • Data not given in these forms is ignored in forming the plot.
  • By default, the encoding enc is automatically chosen based on the forms of the values vali.
  • Possible settings for the encoding enc can be:
  • "Size"vary the point sizes according to the values
    "Color"smoothly color the points according to the values
    "DiscreteColor"discretely color the points according to the values
    "Shape"vary the shape of the point according to the values
    "Label"label the points with the values
    funcapply func to the values to determine the point marker
    nencencode the n^(th) value for a point with the encoding enc
    m;;nencencode the m^(th) through n^(th) values with the encoding enc
    Allencencode all the values for a point with the encoding enc
    {enc1,enc2,}use different encodings for different values

Basic Examples  (5)

Points are shown using different colors for numeric values:

Multiple numeric values are displayed as plots:

Use size to represent the values associated with the points:

SpatialPointData objects include both location and values:

Encodings  (6)

Different values are mapped to different visual encodings:

Use color to encode the second value and size for the third:
