Example 1: Plotting Two Lines in Same ggplot2 Graph Using geom_line() Multiple Times In this Example, I’ll illustrate how to draw two lines to a single ggplot2 plot using the geom_line function of theggplot2 package. For this, we have to specify our x-axis values within the aes of...
Consider Figure 3.1, one attempt to answer this question. It is a scatterplot of two continuous variables (engine displacement and highway mpg), with points coloured by a third variable (number of cylinders). From your experience in the previous chapter, you should have a pretty good feel fo...
Plot one or several time series A time series is the visual representation of time-dependent data, this is, its a chart that represents the evolution of a variable through time. Generally, the pair of points are connected with lines and the decision of showing the points or not depends on...

Lines over grouped bars It is possible to add lines over grouped bars. In this example, there are actually four lines (one for each entry forhline), but it looks like two, because they are drawn on top of each other. I don’t think it’s possible to avoid this, but it doesn’t...

In the scatterplot examples above, we implicitly used a point geom, the default when you supply two arguments to qplot(). # These two invocations are equivalent. qplot(Sepal.Length, Petal.Length, data = iris, geom = "point") qplot(Sepal.Length, Petal.Length, data = iris) But we can...
