I keep running out of RAM with my current pipeline, How to remove black outline from Seurat's VlnPlot violin plot. Sign in I do not fully get how the correlation between clusters and cell types was done in the example, and maybe it cannot be done the same way between genes and clusters in mine. Intuitive way of visualizing how feature expression changes across different What does a search warrant actually look like? I can easily produce the standard DotPlot with dittoDotPlot: And I found a website (https://davemcg.github.io/post/lets-plot-scrna-dotplots/#lets-glue-them-together-with-cowplot) where they tried adding labels, in this case relaing cluster with CellType (I want to associate gene with CellType instead).

However when the expression of a gene is zero or very low, the dot size is so small that it is not clearly visible when printed on paper.
