umap发现自己的簇顺序有问题

设置一下因子就好

sample.integrated@meta.data$integrated_snn_res.0.9 <- factor(sample.integrated@meta.data$integrated_snn_res.0.9,levels = c(0:(max(as.integer(sample.integrated@meta.data$integrated_snn_res.0.9))-1)))

ggplot绘制umap图

你到底想要什么样的umap/tsne图
提坐标

#ggplot
sample.integrated<-AddMetaData(sample.integrated,sample.integrated@reductions$umap@cell.embeddings,col.name = colnames(sample.integrated@reductions$umap@cell.embeddings))
head(sample.integrated@meta.data)
umap <-  ggplot(sample.integrated@meta.data ,aes(x=UMAP_1,y=UMAP_2,color=integrated_snn_res.0.9))+
  geom_point() 
umap
