3. Legend Description

The x-axis represents the logarithmic scale with base 2 (log2(FC)), and the y-axis represents the negative logarithm (base 10) of the significance test P value or FDR value, that is, -log10(p) or -log10(FDR). Different colors of the points indicate the significance of the differences between the two groups of samples. The points in the upper left and upper right corners respectively represent the significantly down-regulated and up-regulated genes, and the uncolored points indicate that the gene differences are not significant.
