Flame Chart Node

The Flame Chart Node visualizes hierarchical data as a series of stacked bars, making it easy to analyze resource usage or performance over time.

Overview​

This node requires the user to provide hierarchical data, where each bar represents a segment of the hierarchy. The width of each bar corresponds to the duration or size of the segment.

Key Features​

  • Hierarchical visualization: Display nested structures in an intuitive format.
  • Performance analysis: Ideal for profiling applications or resource usage.
  • Interactive exploration: Zoom and pan through large datasets.
  • Dashboard ready: Integrates seamlessly with dashboards for detailed analysis.

Required Data​

  • hierarchyColumn: The column defining the hierarchy.
  • durationColumn: The column representing the duration or size.
  • colorColumn (optional): For custom coloring of bars.
  • zoom, pan, logScale, grouping: Additional display options.

How it works​

  1. Add the Flame Chart Node to your workflow.
  2. Connect your dataset.
  3. Select the hierarchy and duration columns.
  4. Configure display options as needed.
  5. The node renders a flame chart.

Use Cases​

  • Application profiling: Analyze function call durations in software.
  • Resource allocation: Visualize resource usage across hierarchical categories.
  • Workflow analysis: Track time spent in different stages of a process.

Benefits​

  • Intuitive visualization of hierarchical data.
  • Flexible configuration for detailed analysis.
  • Handles large datasets efficiently.
