## Data and privacy

This card uses its configured properties and live card data.

## Properties

For theme, background, accent and position, see [Common properties](/docs/cards/#common-properties).

Set static properties in `params`. Bind `data` to a project card data key for live values; that document holds only dynamic properties. Without a data key, put the complete configuration in `params`. Nested rows describe the contents of their parent property.

| `kind` | string | `"column"` | `"column"`, `"bar"`, `"line"`, `"area"`, `"donut"` | column: vertical bars; bar: horizontal bars; donut uses the first series. |
| `prefix` | string | `""` | maxLength: `3` | Before every value, for example $. |
| `unit` | string | `""` | maxLength: `6` | After every value, for example % or k. |
