# Chart types

> The five chart types and when each one applies.

Chart tiles come in five types. The chart type changes how the same numbers look and which follow-on options become available.

<Tip>
  First time? Use **line**. It supports breakdowns and comparisons, has no constraints, and reads well for almost every time-series question.
</Tip>

For a decision aid when building a tile, see [choosing a chart](/knowledge-v2/referral/reporting/building-dashboards/choosing-a-chart).

## Line

Plots values as a continuous line over time. Best for spotting trends and momentum across a period.

* Supports multiple metrics on one tile (as long as they share the same unit, e.g. two currency metrics).
* Supports breakdowns, which render as multiple lines.
* Supports comparisons, which render as a dashed line.

## Bar

Shows each period as its own bar. Best for comparing discrete periods side by side.

* Supports multiple metrics.
* Supports breakdowns (one bar group per period, segment per breakdown value).
* Supports comparisons.

## Stacked bar

Stacks multiple metrics or breakdown segments into a single bar per period. Best for seeing how a total is composed and how composition shifts over time.

* Use multiple metrics or a breakdown to define what gets stacked.
* Does not support comparisons.

## Funnel

Shows drop-off between sequential metrics. Best for conversion flows where each step is a subset of the previous.

* Metrics should be ordered from widest to narrowest (e.g. Impressions → Sharers → Share Responses → Incented Friends → New Customers).
* Does not support breakdowns.
* Does not support comparisons.

## Share

Shows each segment's contribution as a percentage of the total. Best for proportion and mix analysis at a glance.

* Segments come from multiple metrics or a breakdown.
* Does not support comparisons.

## Constraint summary

| Chart       | Breakdown | Comparison | Multiple metrics |
| ----------- | --------- | ---------- | ---------------- |
| Line        | Optional  | Yes        | Yes              |
| Bar         | Optional  | Yes        | Yes              |
| Stacked bar | Optional  | No         | Yes              |
| Funnel      | No        | No         | Yes              |
| Share       | Optional  | No         | Yes              |

Breakdown and comparison are mutually exclusive on any chart. Adding a breakdown clears the comparison and vice versa.
