Chart style

A basic line chart is a type of line chart in the mobile widget. Compared with a dual axis line chart line chart, a category of a basic line chart corresponds to only one value. A basic line chart displays the changes of different data in the same category by configuring multiple series of data. A basic line chart can intelligently display the multi-dimensional data change trend by combining lines and regions.
