Time Series Line

2. Y-Axis vertical axis, often numerical
3. X-Axis horizontal axis, displaying time intervals
4. Legend key explaining line categories
5. Gridlines lines aiding value reading

When to Use

• Representing information over time, where there are multiple values within each X-Axis interval.
• Comparing multiple sets of information over time, where there are multiple values within each X-Axis interval.

When Not to Use

• Displaying data that is tied to a single value per X-Axis interval, i.e., rolling return. Instead, use a line chart.
• Representing information that is intended for comparison, but not for comparing trends over time. Instead, use a vertical bar chart.

• Too many data sets can clutter the chart and make the information difficult to understand.
• Each line should use the assigned colors for Morningstar data types in the order specified in the design system, if applicable.
