Area chart

Area chart icon

Area Graphs are used to display the development of quantitative values over an interval or time period.


Area charts are conceptually similar to line charts as they display quantitative values over a continuous interval or time period. First drawn by plotting data points and joining a line, the area below the line is then filled with a specified variable or colour.

Select a continuous interval or time period variable (x) along with a numerical variable (y) to create a basic plot. Add in a categorical fill variable to group the area charts based on the values selected, and colour them accordingly. Select a summary_function in order to perform basic statistics upon the y variable selected.
