plot multivariate data into colour channels using geom_tile
normalize.colrange normalizes the range of each column to [0, 1]
normalize.range normalizes the range of all columns to [0, 1]
normalize.null does not touch the values
normalize.minmax normalizes the range of each column j to [min_j, max_j]
legends for mixed colour plots
