Principal component 1 (PC1) and principal component 2 (PC2) are used as the X-axis and Y-axis, respectively, to draw the scatter diagram, where each point represents a sample. The farther the two samples are from each other, the greater the difference is between the two samples in gene expression patternsBack to article page
