Funnel

A funnel chart shows how a metric changes across ordered steps. Use it to measure drop-off, progression, or stability between stages.

A funnel chart shows how a single numeric metric changes across an ordered sequence of steps. Use it to compare stages and measure drop-off, growth, or stability.

It’s ideal for:

• conversion or pipeline steps

• request flows and stage transitions

• resource consumption stages

• stability checks over time (step = timestamp)

What a funnel chart represents

Each row in the funnel represents one step (for example, time, stage, or state).

For each step, the funnel typically shows:

• Step: the stage or time

• Value: the numeric metric

• % Max: value relative to the highest step

• % Previous: value relative to the previous step

Use the Plot panel to choose the step column, value column, and sorting.

Funnel chart options

Use these options to control how the funnel chart renders.

Option	Purpose	Typical values / notes
Step column	Defines what each step represents.	Common: timestamp. Other examples: stage, status, pipeline_step, deployment_phase.
Step column title	Display name for the step column.	Example: step. Cosmetic only.
Value column	Metric to compare across steps.	Must be numeric. Examples: value, memory_bytes, request_count.
Value column title	Display name for the value column.	Example: value. Cosmetic only.
Enable sorting	Sort steps before rendering.	Useful for “top drop-offs” or “largest values first”.
Sort column	Field used for sorting.	Often the same as Value column (for example value).
Sort order	Sorting direction.	Ascending or Descending.
Apply	Applies changes to the widget.	Changes do not render until you click Apply.

Key rules: Step column can be time or stage, Value column must be numeric, and sorting controls the funnel order. % Max shows relative scale, and % Previous shows step-to-step change.

When to use funnel charts

Use funnel charts when you want to:

• track progression

• compare stages

• detect drop-offs

• measure stability
