ggplot(data, aes(x, y))+# Draw ggplot2 plotgeom_line()+geom_point() As shown in Figure 1, we created a line and point plot (i.e. a graph where the lines connect the points) using the ggplot2 package with the previously shown R syntax. ...

As you can see based on Table 1, our example data is a data frame composed of five observations and three columns with the names “group”, “sample”, and “responses”. Let’s assume that we want to create a ggplot2 barchart with a line on top, where the bars represent the sample...
We make dumbbell plot by plotting points for each time point and connect them with a line for each country. In order to connect the points, we need specify which rows or countries need to be connected. We create a new variable that specifies the group corresponding to each country. library...

Line graphsFor line graphs, the data points must be grouped so that it knows which points to connect. In this case, it is simple – all points should be connected, so group=1. When more variables are used and multiple lines are drawn, the grouping for lines is usually done by variable...

This post explains how to build a line chart that represents several groups with ggplot2. It provides several examples with explanation and reproducible code.
Let’s get started by creating the line chart first. This is a line chart that has dots drawn on top of it. In ggplot2 this is as easy as adding a call to geom_point() after geom_line() to ensure the dots are on top of the lines. # Aesthetics defined in the `ggplot()` ca...
