Fields

1. In the Data area on the right, select a dataset, and double-click or drag required dimension and metric fields to the corresponding areas on the Fields tab.

   Table 1 Parameters on the Fields tab

   Parameter	Description
   Field display content	Click in the column and click Field display content to modify the field display content on the displayed page. Click OK.
   Aggregation Mode	Select Aggregation Method and click to support setting of no aggregation, sum, count, distinct count, maximum value, minimum value, average value, population standard deviation, sample standard deviation, sample variance, range start value, and range end value.
   Drilldown	You can enable drilldown for dimension fields. For example, you can view data at different levels of granularity, ranging from years down to quarters, months, weeks, days, hours, minutes, and even seconds, depending on the time dimension. Click the field () in the column and drag the field of the target location to be drilled down to the Drilldown area. Click Update to test whether the drilldown function is set successfully. NOTE: Drill-down is only supported for dimension fields, not for metric fields. You can only select one field as the starting point for drill-down. When drilling down on time, the system will automatically add the subdivided time periods to the drill-down order list and include them in the sorting field (fields that are already in the sorting field will not be added again). Drill-down icons should be highlighted for fields that have already been drilled down. If you remove the drill-down field from the dimension, the entire drill-down function box will disappear.

2. Set the color legend: Drag the desired field into Color Legend (dimensions only) on the Field tab. After setting, the chart will use different colors to distinguish data based on dimensions.
3. Set the tooltips and metric: Drag the desired field into Tooltips/Metric (metrics only) on the Field tab. After setting, the field will appear in the chart's tooltip box.
4. Set a filter.
   1. Find the data field you need in the dimension and metric lists within the data column.
   2. Click next to the field you wish to filter and you will be directed to the filter settings page.
   3. Click OK.

      Table 2 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.

      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.

5. 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.

    2. Select the associated chart and click OK.

    Table 11 Chart linkage configuration parameters

    Parameter	Description
    Filter	Fields to Bound: Select the fields to be bound. Associated Charts: Set linked associated charts. You can select charts from the same dataset or different datasets.
    Shown/Hidden	Select the required fields first and then select the charts to be associated with them. You can select all charts on the large screen. Click Show/Hidden. The Shown/Hidden tab is displayed. Select the associated chart.

• Redirect
  1. On the Interactions tab, click the edit icon next to Redirect under Advanced.
  2. In the Chart Redirect dialog box that appears, click next to Component to Be Bound.
  3. Set Redirect Type, Open Mode, Redirect to Reports/Screens, and Associated Parameters, and click OK. For details, see Redirect Example.
     

     • You can redirect with parameters. For specific examples, refer to Example of Redirection with Parameters.
     • To set up redirection, drag the desired fields to the Fields tab. Then, navigate to the chart redirection page to configure the bound fields. Failure to do so will result in unsuccessful redirection.

     Table 12 Parameters

     Parameter	Description
     Redirect Type	Intra-system redirect: Redirect to the internal screen and dashboard projects. External redirect: Redirect to a link that is not in the software.
     Open Mode	Open in this window: After you click the chart with redirection set, the target chart is opened in the current window. Open in new window: After you click the chart with redirection set, the target chart is opened in a new window. Open in popup window: After you click the chart with redirection set, the target chart is opened as a pop-up window. The size of the pop-up window is customizable.
     Redirect to Reports/Screens	Select a project first. Select a dashboard/screen. NOTE: This step is mandatory when Redirect Type is set to Intra-system redirect.
     Associated Parameters	Set Effective Parameters of This Screen. Associated Parameters: Carry associated fields to the chart that you are redirecting to. Enter a fixed value: The chart that you redirect to only filters the fixed value. For example, if the fixed value is set to city, the chart that you redirect to displays the filtered city field. Control Variables: Each value selected in the drop-down box, search, or tab list is a variable value set by the control variable. For example, if you select city in the drop-down box, the variable value of the control variable is city, and the chart that you redirect to filters out the city field. Global Parameters: Carry the values in the global variables to the chart that you redirect to.
     Carry condition	When Redirect Type is Intra-system redirect, null values can be carried. Carrying null values is mainly used for filtering null values in data tables, making it easier for users to analyze data. Prerequisites: Set up two large screens, A and B, with screen A linking to screen B. Procedure Configure global parameters in screen B and ensure that the same fields exist in screen A. Set the redirect parameters in screen A, select screen B as the target, and choose associated fields from the global parameters. Select Carry null value and click OK. The bound field in screen A will be underlined. Click it to redirect to screen B and filter out rows with null fields. The URL of screen B will display the param parameter. Deselect Carry null value and click OK. The bound field in screen A will be underlined. Click it to redirect to screen B and display all chart data. The URL of screen B will not display the param parameter.
