You have to add a layer with scale_fill_manual: Image 11 – Stacked bar chart with custom colors. Most (~90%) of your day-to-day charts can be probably written with 2-3 lines of code using the hchart and hcaes functions. For the horizontal bar chart, bars will be shown in descending order, with the police force with the largest value at the top of the chart. That’s where labels come in.

Tag: r,ggplot2,bar-chart. Bar charts (or bar graphs) are commonly used, but they’re also a simple type of graph where the defaults in ggplot leave a lot to be desired. The items on the x-axis have x values of 1, 2, 3, and so on, though you typically don’t refer to them by these numerical values. The geom_bar() has two useful parameters: Here’s how to use fill to make your chart Appsilon-approved: Image 2 – Using fill to change the bar color.

When you use position_dodge(width = 0.9), it spaces the bars so that the middle of each bar is right where it would be if the bar width were 0.9 and the bars were touching. This is because position = "dodge" is simply shorthand for position = position_dodge() with the default value of 0.9, but when we want to set a specific value, we need to use the more verbose form.
