路径图:geom_path() 以上函数参数可以画出路径图,其实就是根据每一个数据点的出现先后顺序,依次链接所有点所形成的路径: ggplot(mpg,aes(cty,hwy))+geom_path()...ggplot(mpg,aes(cty,hwy))+geom_point()+geom_path() ? 可以同时...

一、非DOM方法添加 1、document.write()
这很棘手，因为ggplot2使用“color”来控制geom_line颜色和geom_point颜色，所以我不知道一种直接的方法...
You can make use of any of the otherggplot2functions, for example, contours fromstat_density2d. Themappingargument forgeom_spraychartgets passed to the underlyinggeom_point, as do any extra parameters passed into the...argument ofgeom_spraychart, e.g.size=5in the below. ...
