Suitable for scenarios where multiple charts show different perspectives of the same data source. Use Cases # Optimize queries by querying all data once in one dataset and distributing Reduce waste from duplicate queries, query same data only once Usage # In the dashboard development interface, “Add” -> “Shared Data” Configure in “Settings” -> “Advanced” -> “Advanced Settings” Charts 3 and 4 are mapped to the shared dataset (#2) data You can also use the global variable “data_index” in any JS. https://help.smartchart.cn/en/docs/2.Datasets/DatasetForms/LazyLoading/ Mon, 01 Jan 0001 00:00:00 +0000 https://help.smartchart.cn/en/docs/2.Datasets/DatasetForms/LazyLoading/ Introduction # Lazy-load datasets are on-demand triggered datasets. Unlike standard datasets that auto-query on page load, lazy-load datasets require frontend code to call ds_refresh() to trigger. Suitable for data download, multi-level drill-down, and user-interaction-triggered loading scenarios. Use Cases # Similar to frontend-backend development where the backend provides APIs but the frontend doesn’t need to query immediately on page load E.g., data download - only query when user needs to download E.
