scatterutil: Graphical utility functions

Description Details Author(s) See Also Examples

Description

These are utilities used in graphical functions.

Details

The functions scatter use some utilities functions :

scatterutil.base

defines the layer of the plot for all scatters

scatterutil.sco

defines the layer of the plot for sco functions

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

scatterutil.convrot90

is used to rotate labels
