Visualization of Rosenberg data. a Expression of cells from different cell types on marker genes. Columns are cells and rows are marker genes. Cells are grouped according to the (true) cell types that they belong to, with the colorful bar on the top of the expression matrix giving the cell type identities, and the marker genes are grouped according to the cell types that they correspond to. The white vertical and horizontal gaps separate cells from different types and marker genes corresponding to different cell types. The black boxes indicate the correspondences of cell types and marker genes. b The bars show the percentages of cells that have zero expression in the corresponding cell types, for the marker genes
