settings_get [#settings_get]
Read the current chart preferences (theme, grid, axes, time zone, tooltip, renderer, cache limit, colors) and the schema of writable keys with their allowed values.
**参数**
此工具不需要输入。
settings_update [#settings_update]
Apply one or more chart preferences immediately, e.g. \{"values":\{"theme":"light","showGridLines":false}}. Call settings\_get first for allowed keys and values. The same action backs the settings dialog, so the user sees the change at once.
**参数**
| 字段 | 类型 | 必填 | 约束 | 说明 |
| ------------------- | ------------------- | -- | -- | -- |
| values | record | 是 | — | |
**最小输入** · 仅含必填字段，占位值由 schema 推导。
```json
{
"values": {}
}
```
settings_reset [#settings_reset]
Restore chart preferences to their defaults. Pass "keys" to reset only those settings; omit it to reset everything. Returns the previous values.
**参数**
| 字段 | 类型 | 必填 | 约束 | 说明 |
| ----------------- | ---------------------- | -- | -------------------------------------------------------- | -- |
| keys | string\[] | — | min items 1; item min length 1 | |
**最小输入** · 仅含必填字段，占位值由 schema 推导。
