## Graphical utility functions

### 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
