# Chart catalogue

The closed set of charts WerkOS draws, each with the question it answers and its limit.

* Kind: data
* Page: https://design.werklist.com/data/chart-catalogue
* Version: 2.1.2

## When to use it

* Choosing a chart from the question it has to answer

## When not to use it

* A chart that is not in the catalogue: WerkOS does not draw it

## Rules

* Parts of a whole: at most 5 named parts, the rest gathered as a remainder in slate
* Small multiples: columns, trends, donuts, choropleths, dot plots or banded columns, repeated small, 3 across at full width, on one shared scale with one key. Past 9 panels, use a table with a sparkline column
* Not drawn: a pie, a donut with more than 5 parts, a second vertical axis, radar charts, treemaps, packed circles, word clouds, 3D, an area that is neither a running total nor a composition, bars that do not start at zero, a smoothed line through fewer than 4 points, a log scale

## Variants

* Stat tile: The one number a view exists for. Without a figure, the tile says why
* Ranked bars: How large a value is against its peers. Up to 12 rows

* Dot plot: One score on a fixed scale, such as 0 to 100, across many subjects
* Dumbbell: A low and a high for each subject. Up to 20 rows
* Peer band strip: Whether a value is normal for its region and income band
