Seurat dotplot.

I have already checked the Seurat visualization vignette, the option for 2 genes mentioned in #1343 (not suitable for more than 2 genes) and the average mean expression mentioned in #528. This last option would be fine, but I get a lot of noise in clusters that are unimportant for my signature because i.e. ...

Description. Intuitive way of visualizing how gene expression changes across different identity classes (clusters). The size of the dot encodes the percentage of cells within a class, while the color encodes the AverageExpression level of 'expressing' cells (green is high). Splits the cells into two groups based on a grouping variable.Starting on v2.0, Asc-Seurat also provides the capacity of generating dot plots and “stacked violin plots” comparing multiple genes. Using an rds file containing the clustered data as input, users must provide a csv or tsv file in the same format described in the expression visualization section.

DimPlot.Rd. Graphs the output of a dimensional reduction technique on a 2D scatter plot where each point is acell and it's positioned based on the cell embeddings determined by the reduction technique. Bydefault, cells are colored by their identity class (can be changed with the group.by parameter).

I don't understand exactly where your problem lies since I haven't seen the figures, but in general: Seurat outputs ggplot objects, or lists of ggplot objects. If you want to alter i.e. the y axis you can do so using methods from the ggplot package (you can manually set breaks, limits, ticks, etc).
