A line chart, also known as a line graph, is an effective visual tool for illustrating trends over time. Typically, the vertical y-axis represents quantities such as dollars, sales numbers, or customer counts, while the horizontal x-axis measures time intervals, such as years, months, weeks, days, or even hours.
Line charts are versatile and can be used to plot and display various relationships between two values. For instance, they can show how many conversions a marketing campaign received over a year, how many sales occurred in the last quarter, or how social media engagement performed over the past few weeks.
Line chart templates are useful for:
If you're comparing multiple items with several lines on your chart, use a legend to identify what each line represents by color.
Clearly label each axis with the appropriate numeric value or unit of measurement used in your chart.
Select a unit of measurement that effectively highlights changes in your data. For example, using months instead of weeks may make trends more apparent.
Provide a title that succinctly conveys the information your chart displays, helping your audience quickly understand the focus.
