ggplot(data = df, mapping = aes(x = year, y = value, linetype= type)) + geom_line() 同样需要注意的是,在绘制多条折线图时,如果横坐标为因子,必须还得加上‘group=分组变量’的参数,否则报错或绘制出错误的图形。 以上绘制的折线图,均采用默认格式,不论是颜色、形状、大小还是透明度,均没有给出...
将ggplot2::geom_line图例形状更改为类似于ggplot2 2::geom_point的图例形状的“点” 、 这里最重要的工作是将geom_line的图例形状更改为一个geom_point“点”,但在图中保留geom_line。我也知道使用geom_point可以覆盖图例形状,但是这种方法不适用于geom_line。我试图修改GeomPath对象以将draw_key = draw_key_...
