Chart Queries¶

After selecting a chart, you can use multiple query methods to query and analyze data from different categories in depth, so as to visually display numerical information in the chart and reveal important relationships between data.

Query Methods¶

A single chart supports the following query methods:

Simple Query: Suitable for quick queries and basic data analysis;

Expression Query: Perform complex calculations by adding expressions;

DQL Query: Use the system's proprietary DataFlux query language for advanced queries;

PromQL Query: Queries for Prometheus data sources;

Data Sources: Directly connect to external data sources for queries.

Edit Long Queries¶

Long queries can be expanded for editing. After returning, validation and saving continue in the chart configuration. For instructions, see Query Code Input.
