## 11.34 Labels Rotated

When a bar chart has many bars and non-trivial labels then it is useful to rotate the labels. Here we plot the mean temperature at 3pm for each location in the dataset. Without rotating the x-axis labels (the locations) the x-axis will be blighted with much overlapping. Labels can be rotated using a ggplot2::theme() option of axis.text.x= with angle=$45^\circ$. Use hjust=1 to align the labels appropriately.
