In the Settings menu, you’ll be able to choose between a line chart with a single line or multiple lines. A “single line” chart creates a chart with up to 10 points that are connected by a line. A “multiple line” chart creates a chart with 2 different colored lines (2 data sets) that can be compared.
You can also choose how you want to display the values on your line chart. “Reveal values on click” hides the values in the chart. You can click on the points to reveal their value. Alternatively, you can choose to always show the values of the points in the chart.
