Chart Editor
Build and configure charts using the visual flow editor
The Chart Editor is the visual system for building charts in fastStats. You connect nodes on a canvas to define what data to pull, how to transform it, and how to display the result.
Flow Nodes
All available nodes — Data Field, Filter, Aggregate, Group By, Time Group, Formula, and more.
Output & Multi-Series
How to create tabs, multi-line charts, and stacked bars using multiple Output nodes.
How it works
Every chart is powered by a pipeline of nodes. You build it by dragging nodes onto the canvas and connecting them top to bottom:
- Pick your data — start with a Data Field node
- Shape it — add Filter, Group By, Aggregate, or other transformation nodes
- Display it — end with one or more Output nodes
The number of Output nodes controls the chart behavior:
| Output Nodes | What you get |
|---|---|
| 1 | Single series — one line, one bar group, one widget value |
| 2+ | Multi-series — multiple lines, stacked bars, or tabbed lists |
