# Line charts

Line charts are best used to depict a data point in time. They are intuitive to read and relatively straightforward to create.

In a line chart, typically, each data point represents a specific value corresponding to a time interval. These data points are connected by lines to indicate progression or movement. The y-axis reflects the measured metric values. Brilliant Assessments also supports line charts displaying multiple data series on the same graph, making comparing trends or metrics across different datasets easier.

## Single line charts

This style of chart provides a smooth visualization of comparative data over multiple categories. They can be used with either percentage or actual average scores, offering flexibility in interpreting the data.

## Multi-line charts

Used in feedback and cohort reports, Multi-Line Charts show benchmark results alongside individual or group responses, facilitating a multi-layered performance analysis over time or across categories.

## Area chart

Area charts are versatile, used for both comparative analysis and in conjunction with benchmarks. They offer a filled-in view between data lines, making trends easier to spot.
