scale_: 标度是一种函数,它控制了数学空间到图形元素空间的映射。一组连续数据可以映射到X轴坐标,也可以映射到一组连续的渐变色彩。一组分类数据可以映射成为不同的形状,也可以映射成为不同的大小,这就是与aes内的各种美学(shape、color、fill、alpha)调整有关的函数。
Color selection By default, the colors for discrete scales are evenly spaced around a HSL color circle. For example, if there are two colors, then they will be selected from opposite points on the circle; if there are three colors, they will be 120° apart on the color circle; and so ...
每个几何对象都有自己的属性,这些属性的取值需要通过数据提供。数据与图形属性之间的映射关系称为mapping,在ggplot2中用aes()进行定义。常见的图形属性有:x,y,size,color,group。图形属性的任意一项都可以用数据的某一个变量来表示。 标尺scale 前面提到aes()设定了数据与图形属性的映射关系,但是数据怎么映射为属性,...
