 ### How can I display proportions (relative frequencies) instead of counts on a bar plot?
 
-Either calculate the proportions ahead of time and place them on bars using `geom_text()` or let `ggplot()` calculate them for you and then add them to the plot using `stat_coun()` with `geom = "text"`.

--   Dodge axis labels: Add a `scale_*()` layer, e.g. `scale_x_continuous()`, `scale_y_discrete()`, etc., and customise the `guide` argument with the `guide_axis()` function. In this case we want to customise the x-axis, and the variable on the x-axis is discrete, so we'll use `scale_x_continuous()`. In the `guide` argument we use the `guide_axis()` and specify how many rows to dodge the labels into with `n.dodge`. This is likely a trial-and-error exercise, depending on the lengths of your labels and the width of your plot. In this case we've settled on 3 rows to render the labels.

 -   Remove x or y axis labels: If you want to modify just one of the axes, you can do so by modifying the components of the `theme()`, setting the elements you want to remove to `element_blank()`. You would replace `x` with `y` for applying the same update to the y-axis. Note the distinction between `axis.title` and `axis.ticks` -- `axis.title` is the name of the variable and `axis.text` is the text accompanying each of the ticks.

 Note that the blue circle is partially covered by the yellow triangle since that observation comes later in the dataset.
