  Assume that the first three records of the static data are modified as follows:

  [
    {
      "x": "Type A",
      "y": 78,
      "s": 1
    },
    {
      "x": "Type A",
      "y": 55,
      "s": 2
    },

Data

• Data Source Type: to select the data source of the chart. Multiple data sources are provided for you to select. You need to add data sources first. For details, see Data Connection Overview.
• Converter: Select a converter to convert data into the data that meets the display requirements. For details, see Using a Converter.
• Data Mapping: The data format contains the following fields by default. Set the field names in the data source to which each field is mapped. If the field names are left empty, the field names are the same as those in the data source to which each field is mapped.
  • x: category, corresponding to the X axis.
  • y: data of series, corresponding to the Y axis.
  • s: series. You can set a value of the s field to a series. Multiple series can be added.

    Click on the right of s to add a series. To delete an added series, click on the right of the series.

    Add a series as follows:

    • Series Value: Enter a value of the s field. If the series value is empty, the value of the corresponding s field is used by default.
    • Series Name: self-definable. If the series name is empty, the series value is used as the series name by default.
    • Color: color of the column in the series.
    • Stack: stack name. You can enter a user-defined name. If the same stack name is set for different series (with different s values) of the same category (with the same x value), the series data is displayed in the stack.
    • Link: target link to which the web page points when a data item in component widget is clicked.
    • Link Mode:
      • New window: The target link opens a new browser window.
