- Bar charts in R. A bar chart is a kind of graph that is usually used to compare different categories. It represents every category as a rectangular bar, with the height/width of the rectangle along the opposite axis representing the frequency of the category. Bar charts can also represent data with complex categories as stacked bar charts.
- The height of each bar is always the full height of the chart diagram (i.e. 1). The series values are displayed as percentages of each bar. A Full-Stacked Bar chart is shown in the image below. Note that this chart type is based upon the XYDiagram, and so it can be rotated to show bars either vertically or horizontally.
- By clicking the Stacked Bar Chart under the Visualization section, it automatically converts the Column Chart into Stacked Bar Chart. Next, let me add Color to Axis section to create a Bar chart that shows Sales Amount by Color. Next, we are adding the English Country Region Name to the Legend section to convert it into the Stacked Bar Chart.
