Biplot constructed by superimposing a PCA plot of 62 lymphoma samples (see Fig. 6) onto a PCA plot of genes where first and second principal component for the genes are calculated from gene expression profiles comprising expression levels of the 62 samples for each gene. Genes are represented in the plot as small green dots. Genes representing the three classes well are indicated by numbers. Source: [39]
