Create a single line plot. Change the linetype option to “dashed”. library(ggplot2) ggplot(data = df, aes(x = dose, y = len.mean, group =1)) + geom_line(linetype ="dashed")+ geom_point() Create a line plot for multiple groups. Change line types by groups. ...
qplot(weight, data = wdata, geom = "density", color=sex, linetype=sex) ggplot() 上文中的qplot()绘制散点图: qplot(x=mpg, y=wt, data=df, geom = "point") 在ggplot()中完全可以如下实现: ggplot(data=df, aes(x=mpg, y=wt))+ ...

在ggplot2中,如何让geom_line为同一组的不同数据系列显示不同的图例项? 在ggplot2中,如果你想要为同一组的数据创建两个不同的图例,可以通过对数据进行适当的转换和使用guides()函数来实现。以下是一个示例,展示了如何为同一组数据创建两个不同的图例。
time: x-axis sex: line color total_bill: y-axis.To draw multiple lines, the points must be grouped by a variable; otherwise all points will be connected by a single line. In this case, we want them to be grouped by sex.# Basic line graph with points ggplot(data=dat1, aes(x=...
This way, with just one call to geom_line, multiple colored lines are drawn, one each for each unique value in variable column. The scale_x_date() changes the X axis breaks and labels, and scale_color_manual changes the color of the lines. data(economics_long, package = "ggplot2") ...
