偶然间找到了一份教程利用ggplot2绘制环状柱形图,个人感觉非常适合用来展示叶绿体基因组蛋白编码基因的dn/ds值,因为不仅能够通过柱状图的高低来比较dn/ds值的大小,还能够通过环状展示蛋白编码基因在叶绿体基因组上所处的位置 A circular barplot is a barplot where bars are displayed along a circle instead of a li...

ggplot2.barplot is a function, to plot easily bar graphs using R software and ggplot2 plotting methods. This function is from easyGgplot2 package. An R script is available in the next section to install the package. The aim of this tutorial is to show you step by step, how to plot an...
R语言barplot函数,标度控制着数据到图形属性的映射,当有需要时,ggplot2会自动添加一个默认的标度。我们确实可以在不了解标度运行原理的情况下画出许多图形,但理解标度并学会如何操纵它们则将赋予我们对图形更强的控制能力。每一种图形属性都拥有一个默认的标度,此标度
