Statistics[AgglomeratedPlot] - generate agglomerated plots

Calling Sequence

AgglomeratedPlot(X, Y, Z, options, plotoptions)

Parameters

X

-

first data sample

Y

-

(optional) second data sample

Z

-

(optional) third data sample

options

-

(optional) equation(s) of the form option=value where option is one of length, or n; specify options for generating the agglomerated plot

plotoptions

-

options to be passed to the plots[display] command

Description

• 

The AgglomeratedPlot command generates an agglomerated plot for the specified data. This type of plot is often used by cartographers or when there is a large number of data points involved. The aim is to remove the unnecessary detail of each individual point in a plot, and replace dense regions of data with boxes.

• 

If n or more points are found within a cube, whose size is defined by length, then they are replaced by the tightest fitting box possible. If n^2 or more points are found within the same cube, then the box will emphasized with thicker borders.

• 

The parameters X, Y and Z are the data samples to be plotted. Each can be given as a Vector, Matrix, Array, or list, though they do not all have to be of the same type. They also do not need to be one dimensional, but will be treated as though they are. The first data sample, X, is required, but the second and third data samples, Y and Z respectively, are optional. Note that all data samples must have the same number of elements.

• 

This function is part of the Statistics package, so it can be used in the short form AgglomeratedPlot(..) only after executing the command with(Statistics).  However, it can always be accessed through the long form of the command by using Statistics[AgglomeratedPlot](..).

Examples

withStatistics:

data:=SampleRandomVariableNormal0,1,75:

AgglomeratedPlotdata,n=2.5,length=0.25,size=600,200

A:=SampleRandomVariableNormal0,1,200:

B:=SampleRandomVariableNormal0,1,200:

C:=SampleRandomVariableNormal0,1,200:

AgglomeratedPlotA,B,C,n=2,length=0.5

The commands to create the plots from the Plotting Guide are

data1:=SampleRandomVariableNormal0,1,40:

data2:=SampleRandomVariableNormal0,1,40:

AgglomeratedPlotdata1,data2,n=2

A:=SampleRandomVariableGammaDistribution1,1,30:

B:=SampleRandomVariableGammaDistribution1,3,30:

C:=SampleRandomVariableNormal0,1,30:

AgglomeratedPlotA,B,C,n=2,length=0.5
