MA-plot. MA-plot for differential expression analysis in four RNA-seqsamples with two cell lines GM12878 and K562, annotated to illustrate the useof the grammar of graphics. Points is our geometric object, x axis indicatesthe normalized mean and the y axis indicates the log2 fold change.Aesthetics mapping took place between the groups and the color to use red toindicate the most significant differently expressed observation (gene). Thisplot uses Cartesian coordinates.
