Default value is: mainTitleFont=c(14, “bold”, “black”). x: character string containing the name of x variable. R Programming Server Side Programming Programming A dot plot is a type of histogram that display dots instead of bars and it is created for small data sets. 2.1.0) Enjoyed this article? As you can see in the above plot, y axis have different scales in the different panels. data.frame or a numeric vector. The function geom_dotplot () is used. This can be also used to indicate group colors. You can view the ggplot2 page for more information.. The humble stacked dot plot is, I think, often preferable to the histogram as a means of graphing distributions of small data sets. The point geom is used to create scatterplots. Introduction ggplot2.dotplot is an easy to use function for making a dot plot with R statistical software using ggplot2 package. Color can also be changed by using names as follow : It is also possible to position the legend inside the plotting area. In a dot plot, the width of a dot corresponds to the bin width (or maximum width, depending on the binning algorithm), and dots are stacked, with each dot representing one observation. I’d be very grateful if you’d help it spread by emailing it to a friend, or sharing it on Twitter, Facebook or Linked In. Possible values for y axis scale are “none”, “log2” and log10.
