Based on a line chart, the area chart fills the section between a line and the axis with color. The filled section is an area block and the color highlights the trend. Similar to a line chart, an area chart emphasizes the number changes over time, and is used to highlight the trend of the total number. Both the line chart and the area chart are mostly used to indicate the trend and relationship, but not to display specific values.

  • Y-axis (vertical)

  1. On the search page of a Logstore, enter a query and analysis statement in the search box, set the time range, and then click Search & Analysis.
  2. On the Graph tab, click to select the area chart.
  3. On the right-side Properties tab, configure the properties of the area chart.
    Note In an area chart, a single area block must contain more than two data records to guarantee that the data trend can be analyzed. We also recommend that you configure no more than five area blocks in an area chart.
