Figure 2. The correlation between CCNB1 and immune cell infiltration. Each point (in black) in the figure represents a sample. The abscissa is the content of an immune cell, and the expression of a gene in the ordinate. R > 0 suggests that the gene is positively correlated with the content of an immune cell, R < 0 suggests that the gene is negatively correlated with the content of an immune cell.
