About Line Chart

A line chart is a statistical chart composed of points and lines in a Cartesian coordinate system, commonly used to represent changes in values over continuous time intervals or ordered categories. In a line chart, the x-axis is typically used for continuous time intervals or ordered categories, while the y-axis is used for quantitative data — negative values are plotted below the x-axis. Lines connect adjacent data points. Line charts are used to analyze trends of things changing over time or ordered categories. Data-wise, a line chart requires a continuous time field or a categorical field and at least one continuous data field.
