FAQ
Chart Selection
Which chart should I use?
Answer: Choose based on your data and goals:
- Trend or change: line or area
- Value comparison: column or bar
- Composition: pie or donut
- Correlation or distribution: scatter
- Hierarchy or stage progress: funnel
For more chart types, see the ECharts examples.
What chart types does NocoBase support?
Answer: Visual mode includes common charts (line, area, column, bar, pie, donut, funnel, scatter, etc.). Custom mode supports all ECharts chart types.
Data Query Issues
Do Visual and SQL modes share configurations?
Answer: No. Their configurations are stored separately. The mode used in your last save takes effect.
Chart Options
How do I configure chart fields?
Answer: In Visual mode, select fields according to the chart type. For example, line or column charts require X and Y fields; pie charts require a category field and a value field. Click Run query first to verify the data; field mapping is automatically matched by default.
Preview and Save
Do I need to preview changes manually?
Answer: In Visual mode, changes are auto‑previewed. In SQL and Custom modes, to avoid frequent refreshes, finish editing and click Preview manually.
Why is the preview lost after closing the dialog?
Answer: Preview is for temporary viewing. Save changes before closing; unsaved changes are not retained.
