Scatter Plot
Description
scatter is a generic function. It has methods for the classes coa, dudi, fca, acm and pco.
The scale of the grid is situated on the right-top of the graph.
The points are in the middle of the labels.
This process plots the graphs of the multivariate analyses.
The two axes have the same scale.
Usage
scatter(x, ...)
Arguments
x
an object used to select a method
... further arguments passed to or from other methods
Details
The functions scatter use some utilities functions :
scatterutil.base defines the bottom of the plot for all scatters
scatterutil.chull plots the polygons of the external contour
scatterutil.eigen plots the eigenvalues bar plot
scatterutil.ellipse plots an inertia ellipse for a weighting distribution
scatterutil.eti.circ puts labels on a correlation circle
scatterutil.eti puts labels centred on the points
scatterutil.grid plots a grid and adds a legend
scatterutil.legend.bw.square puts a legend of values by square size
scatterutil.legend.square.grey puts a legend by squares and grey levels
scatterutil.legendgris adds a legend of grey levels for the areas
scatterutil.scaling to fit a plot on a background bipmap
scatterutil.star plots a star for a weighting distribution
scatterutil.sub adds a string of characters in sub-title of a graph
