The Variable Manipulation option allows variables to be rescaled,
cloned and manipulated and new variables to be created. The Transform
Variables option allows us to view various transformations of the
variables, including Log transforms, rescaling, and
standardisation. Sphering performs a visual principal components
analysis. The Color Scheme option allows us to change the colours used
in our plots. Automatic Brushing will colour various ranges of the
values of each variable. Subsetting and Sampling allows us to choose
subsets of the whole dataset using different methods, including random
sampling, selection of blocks of data, every th entity, and several
others. There are also options to specify Graph Layout and Graph
Options.
