Fig. 3

Distributions of EGFR mutant samples described with the first 3 selected features. a, c and e are for EGFR mutant-erlotinib complexes and b, d and f are for EGFR mutant-gefitinib complexes. a and b are projections of the mutant features to the first and second selected features. c and (d) are projections of the mutant features to the first and third selected features. e and f are projections of the mutant features to the second and third selected features. Here, red, green and blue circles represent mutant groups that correspond to high, moderate and low sensitivity to gefitinib / erlotinib, and’+’ stands for the centroid of each group
