Examples with code and interactive charts.

Line type in ggplot2. In this example we show you how to change the line type of line plot Change the Line Type in an R ggplot Line Plot Importing the ggplot2 library library ggplot2 Creating basic Line Plot ggplot economics aes date pop geom_line color midnightblue linetype 5 arrow arrow ends both type closed. These are useful for annotating plots. Change line types by groups In the graphs below line types and point shapes are controlled automatically by the levels of the variable supp.

The line type for others cat should be dotted. Libraryggplot2 ggplotdatadf aesxtime ybill group1 geom_line geom_point ggplotdatadf aesxtime ybill group1 geom_linelinetype dashed geom_point Line plot. Figure 1 shows the output of the previous R code A basic line plot with relatively thin lines created by the ggplot2 package.

The type of geom you select dictates the type of chart make. The bottom layer shows points and the layer above it shows a red horizontal line. With ggplot2 shapes and line types can be assigned overall eg if you want all points to be squares or all lines to be dashed or they can be conditioned on a variable.
