    theme_cowplot() +

  I have performed a Seurat PCA via [Dimplot](https://satijalab.org/seurat/reference/dimplot).
  
  How do I extend the x axis?
  
  As you can see in my figure the double x axes overlap. [![enter image description here](https://i.sstatic.net/Jf7Ym.png)](https://i.sstatic.net/Jf7Ym.png)

  Looking at the source code for Seurat's `DimPlot()` it's based on ggplot2 graphics (<https://github.com/satijalab/seurat/blob/HEAD/R/visualization.R#L794>), so you can manipulate the dimplot object and save it using ggplot2 commands. Using `ggsave()` you can specify the figure dimensions; if you increase the width of the final figure it should 'fix' your label overlap issue, i.e.
  
  ```r
  #BiocManager::install("Seurat")
  library(Seurat)
  #> Attaching SeuratObject
  library(ggplot2) # for plotting
  library(cowplot) # for the theme used by Seurat
  
  # example data
  data("pbmc_small")
  p <- DimPlot(object = pbmc_small, split.by = "ident")
  
  # example dimplot
  p
  
  ```

  ```r
  # increase font size to make the labels overlap

    theme_cowplot(font_size = 28) +
    theme(strip.background = element_blank())
  
  ```

  ```r
  # save the 'overlapping label' figure and specify a relatively large width to 'space out' the three facets
  ggsave("dimplot_test.png", width = 40, height = 10, units = "cm")
  
  ```

  As a direct answer to your question, restrict the output to producing a single column:
  
  ```
  Dimplot(..., ncol=1)
  
  ```
  
  But this doesn't seem like a useful answer. Please provide more context to your question if you want more help than this.
