A line chart reveals trends or changes over time. They can be used to show relationships within a continuous data set, and can be applied to a wide variety of categories, for example, the daily number of visitors to your website, or variations in stock prices.

Best practice:

  • Clearly label your axes to make sure the viewer knows what they are assessing.
  • Remove distracting chart elements, for example, bulky legends can distract the viewer from quickly seeing the overall trend.
  • Avoid comparing more than 5-7 variables - you don't want your chart to become cluttered or hard to read.
  • Have your 'Tooltip' on to enable the reader to view multiple data sets easily, find out more here.
