A line chart presents the changing trend of data through broken lines and shows continuous data that changes over time. Line charts are useful for analyzing and showing data trends at equal intervals. Line charts are also used for analyzing the interactions among multiple groups of data that change over time. For example, analyzing the sales volume of a certain product or related products for the prediction of future sales.
A line chart is based on the category axis and the value axis. The category axis is the horizontal axis. The categories are required to be dimensions such as dates, provinces, and product types. The value axis is the vertical axis. The values are required to be measures such as performance indicators and order numbers.
Dimensions and measures are automatically used for the category axis and the value axis respectively in the dashboards. You only need to select fields from the Dimensions and Measures lists.
