4.17.1 Attributes
| Name | Type | Default Value | Description |
|---|---|---|---|
| bg-color | color | The background color. | |
| color | color | navy | The plot color. |
| scale-bidir | boolean | false | Enables scaling of the lower boundary, so negative values won't 'drop off'. |
| scale-holdmax | boolean | false | Enables a hold-function on the scaling. When the scaling is changed because of large values, it will not return to the default scaling once those large values have disappeared from the history. |
| size | integer | 50 | The numbers of values stored in the history. |
| value | integer | The next value to append to the history of values. Values may range from 0 to 100, but if you supply values greater than 100, the graph will scale accordingly. |
