In scanpy, there is a function to create a stacked violin plot.
There is no such function in Seurat, and many people were asking for this feature. e.g. https://github.com/satijalab/seurat/issues/300
The developers have not implemented this feature yet. In this post, I am trying to make a stacked violin plot in Seurat.
The idea is to create a violin plot per gene using the VlnPlot in Seurat, then customize the axis text/tick and reduce the margin for each plot and finally concatenate by cowplot::plot_grid or patchwork::wrap_plots.
