Other Options

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 $n$th entity, and several others. There are also options to specify Graph Layout and Graph Options.
