The configuration of the Chart panes. Panes are used to split the Chart into two or more parts. The panes are ordered from top to bottom. To associate each axis with a pane, set its pane option to the name of the desired pane. Axis that do not have a specified pane are placed in the top (default) pane. To move a series to the desired pane, associate them with an axis.

pannable

Specifies if the Chart can be panned.

renderAs

Sets the preferred rendering engine. If not supported by the browser, the Chart switches to the first available mode.

The supported values are:

• "svg"—If available, renders the component as an inline .svg file.
• "canvas"—If available, renders the component as a canvas element.

resizeRateLimit

Limits the automatic resizing of the Chart. Sets the maximum number of times per second that the component redraws its content when the size of its container changes. Defaults to 10. To disable the automatic resizing, set it to 0.

Copy Code@Component({
    selector: 'my-app',
    template: `
        <kendo-chart [resizeRateLimit]="2">
<!--                 ^^^^^^^^^^^^^^^^^^^^^^
      Will update the size of the Chart up to two times a second.
      Resize the Plunkr pane or window to try it out.

  `
})
export class AppComponent {

}

series

The configuration of the Chart series. The series type is determined by the value of the type field. If a type value is missing, the Chart renders the type that is specified in seriesDefaults. Some options accept functions as arguments. These arguments are evaluated for each point which is supplied as a parameter. If no value is returned, the Chart uses the theme or seriesDefaults values.
