然后,用户需要在R编程语言中,用绘制好的ggplot2图带着所需的参数调用scale_x_continous()/scale_x_continous()函数,将轴间隔改为对数刻度。 scale_x_continuous() / scale_y_continuous()函数用于连续位置标度(x和y)。 语法。 scale_x_continuous(…, expand = waiver()) scale_y_continuous(…, expand =...

R Copy输出方法2:手动设置颜色scale_fill_manual( ) 这个函数用来提供自定义颜色。我们可以把颜色代码写成 “#XXXXXX“,也可以直接把颜色名称写成 “color_name“。填充将在ggplot2内部进行,因为我们需要手动为条形图分配不同的颜色。调用该函数并手动插入一个由颜色代码或颜色名称组成的向量。矢量的长度应该与条形...

Ggplot2 layers. Image created by the Author. Below, our mapping (aes()) tells ggplot to make the position on the x-axis dependent on the variable "DATE" and the position on the y-axis dependent on the temperature. Note that if you plot only this layer, ggplot will show you the axes...

The disappearance of many North American megafauna at the end of the Pleistocene is a contentious topic. While the proposed causes for megafaunal extinction are varied, most researchers fall into three broad camps emphasizing human overhunting, climate c
