Field

Set the fields of the heatmap.

1. On the Field tab, double-click or drag and drop required fields to the Dimension, Y Axis/Dimension, and Metric areas in sequence.
2. Set a filter.
   1. Drag dimension and metric fields to the Filter area.
   2. Click next to a field in the Filter area.
   3. In the displayed Set Filter dialog box, set the parameters and click OK.

      Table 1 Filter parameters

      Type	Parameter	Description
      String	Condition	Filter Mode: The options are Condition and Enumeration. Condition Type: The options are And condition and Or condition. Filter Condition: The options are Exact match, Contain, Start with, End with, Not match, Not contain, Null, and Not null.
      	Enumeration	Query Mode: The options are Single-select and multi-select. Filter Condition: The options are >, ≥, <, ≤, =, ≠, Null, and Not null.
      Metric	Condition Type	The options are And condition and Or condition.
      	Filter Condition	The options are >, ≥, <, ≤, =, ≠, Null, and Not null. You can select Before aggregation and After aggregation for data. NOTE: If you select Before aggregation, data is filtered before aggregation. If you select After aggregation, data is filtered after aggregation. For aggregation concepts, see Creating a Dataset. You can click Create Filter Condition to set multiple filter criteria.
      Date	Range value	Select a time range for filtering.
      	Single value	Set a single time for filtering.
      	Condition	You can select And condition or Or condition as the condition type and select filter condition like >, ≥, <, ≤, and =. You can click Create Filter Condition to set multiple filter criteria.

3. Set sorting.
   1. Drag and drop required data fields from the Dimension and Metric (Indicator) areas under Data to the Sorting area.
   2. Click next to a field in the Sorting area and select a sorting mode. The sorting modes are Ascending, Descending, and Custom.
   3. To cancel sorting, click next to the sorting field.
4. Set the maximum number of query results.

   Enter the maximum number of records that can be returned in the text box. The default value is 1000.

5. Set automatic refresh.

   The auto refresh interval supports the following options: no refresh, 1 minute, 5 minutes, 15 minutes, and 30 minutes.

Style

Set heatmap style parameters based on Table 2, Table 3, and Table 4.

Advanced

• Linkage

  Click the Advanced tab and click next to Linkage. The Chart Linkage Settings page is displayed. Set parameters. For details, see Linkage example.

  Table 5 Chart linkage settings

  Parameter	Description
  Fields to Bound	Select the fields to be bound first and then select the chart to be associated with them. You can select all charts on the dashboard.
  Associated Charts	Set linked associated charts. You can select charts from the same dataset or different datasets. Follow bound field: When the bound field is set to A, the associated data tables filter data related to A. SQL placeholder: The bound field value corresponds to the value set for the SQL placeholder in the dataset.

• Initialize Query for Associated Query Control: whether the associated query control supports query initialization. If the checkbox is selected (), the control supports query initialization. If the checkbox is not selected (), the control does not support query initialization.
  

  If you select this option, when a chart is linked to a query control and the query control does not have a default query set, the chart's data configuration will be queried during chart initialization.
