Line Chart
Line charts are useful for analyzing trends in data over time. For example, analyzing changes in product sales over time and predicting future sales. This section will show you how to add data and configure styles for line charts.

- The metric axis is determined by the metrics of the data and at least one metric must be selected, such as order quantity.
- The color legend is determined by the dimensions of the data and only one dimension can be selected.
- The color legend can only be enabled when a metric field is selected on the value axis.
- The chart will display label values if the query limit is 14 or less, but not if it is greater than 14.

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 (
