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=...
You want to use colors in a graph with ggplot2. Solution The default colors in ggplot2 can be difficult to distinguish from one another because they have equal luminance. They are also not friendly for colorblind viewers. A good general-purpose solution is to just use the colorblind-friendly...
This post explains how to build a line chart that represents several groups with ggplot2. It provides several examples with explanation and reproducible code.
