交互式动态火山图
简介
交互式动态火山图用来展示差异基因等,形如火山,故名。鼠标悬停在数据点上,显示该点的信息(基因名,log2fc,p)。点击数据点会标记基因名,基因名可以拖动到合适的位置。再次点击则去掉标记。
标记好感兴趣的基因后,点击导出按钮,导出图片:svg矢量图,高质量png和jpg格式图片
数据说明
数据包括3列,第1列是基因名,或者miRNA名,circRNA名字等,必需唯一;第2列是log2fc,上调>=0,下调<0,不能为空,inf,-inf;第3列为p值或fdr值,不能为空,NA等
论文例子

文章写作
Volcano plot of differentially expressed genes between cancer and normal. Red dots represents upregulated genes, blue dots represents downregulated genes, and gray dots represent genes that were not differentially expressed (P < 0.05, |logFC|>1.0).
