ZoomCharts.FacetChart

Inheritance hierarchy

This type inherits from BaseApi.

Constructors

.ctor: (settings: FacetChartSettings)
Parameters
settings: FacetChartSettings
Return value
Data type: FacetChart

Methods

addData: (data: FacetChartDataObjectRoot, sourceId?: string): void
Inherited from: BaseApi

Adds the given data to whatever data the chart has currently loaded. The chart will automatically be updated to display this new data if it falls within the currently visible bounds.

Parameters
sourceId: string

the ID of the data source that will be updated. The default value is default.

back: (): this
Inherited from: BaseApi
Return value
Data type: this
clearHistory: (): this
Inherited from: BaseApi
Return value
Data type: this
customize: (name: string): this
Inherited from: BaseApi

Applies one of the built-in themes to the chart. This is an alternative to calling updateSettings({ theme: ZoomCharts.FacetChart.themes.dark }).

Parameters
name: string

The name of the theme to be applied, must be one of the values defined in the FacetChart.themes static property.

Return value
Data type: this

Parameters
origin: string
Return value
Data type: boolean
export: (type: "png" | "jpg" | "pdf" | "csv" | "xlsx", dimensions?: BaseExportDimensions, transparent?: boolean, fileName?: string): void
Inherited from: BaseApi

Launches a file download that contains an image or the data of the current state of the chart.

Note that in some browsers calling this method will send the data to a proxy. When handling sensitive data you should install the proxy on your own server, see advanced.exportProxyURL setting.

Parameters
type: "png" | "jpg" | "pdf" | "csv" | "xlsx"

The format in which the data will be exported.

dimensions: BaseExportDimensions

Specifies the dimensions for the image formats.

transparent: boolean
Version 1.12.0: default changed to false.

Specifies if the resulting image should have transparent background. This setting is only valid for png image format. Default is false.

Note that if area.style.fillColor is set, this will have no effect.

fileName: string

Specifies the fileName to be used, excluding fileExtension

exportAsString: (type: "png" | "jpg" | "pdf" | "csv" | "xlsx", callback: (dataUri: string, mimeType: string, extension: string) => void, dimensions?: BaseExportDimensions, transparent?: boolean): void
Inherited from: BaseApi

Saves the current chart state as a data-URI.

If image type is specified, the URI can be used as the image source in <img src="">.

Note that some output settings might require sending the data to a proxy. When handling sensitive data you should install the proxy on your own server, see advanced.exportProxyURL setting.

Parameters
type: "png" | "jpg" | "pdf" | "csv" | "xlsx"

The format in which the data will be exported.

callback: (dataUri: string, mimeType: string, extension: string) => void

The callback that will be invoked once the result is generated.

Parameters
dataUri: string

The data-uri that contains the generated image or data file.

mimeType: string

The mime type of the generated file.

extension: string

The extension of the generated file.

dimensions: BaseExportDimensions

Specifies the dimensions for the image formats.

transparent: boolean

Specifies if the resulting image should have transparent background. This setting is only valid for png image format. Default is false.

Note that if area.style.fillColor is set, this will have no effect.

sourceId: string
remove: (): void
Inherited from: BaseApi

Removes chart from DOM. This method is automatically called when you create a new chart within the same container element.

This method should always be called when the chart HTML element is removed as otherwise there might be additional resources such as event handlers remaining that will prevent the browser from properly releasing memory.

replaceData: (data: FacetChartDataObjectRoot, sourceId?: string): void
Inherited from: BaseApi

Replaces the data already in the data cache with the given values.

Parameters
sourceId: string

the ID of the data source that will be updated. The default value is default.

Use `replaceSettings({series: seriesData})` instead.

Replaces the existing series configuration with new one instead of merging it like updateSettings.

Parameters
Return value
Data type: this
replaceSettings: (changes: FacetChartSettings): this
Inherited from: BaseApi
Introduced in version 1.10.0.

Updates the chart settings but instead of merging some settings that are arrays or dictionaries (such as data) these collections are replaced completely. For example, this allows removal of series or value axis within TimeChart.

Parameters
Return value
Data type: this
restoreState: (state: string, animate?: boolean): void
Inherited from: BaseApi
Parameters
state: string
animate: boolean
resumePaint: (): void

Decrements the suspend counter that was set using suspendPaint() method.

This method also automatically schedules an async repaint.

saveAsImage: (type: "png" | "jpg" | "pdf" | "csv" | "xlsx", dimensions: BaseExportDimensions, transparent: boolean): string
Inherited from: BaseApi
This property is deprected; use `exportAsString` instead

Parameters
type: "png" | "jpg" | "pdf" | "csv" | "xlsx"
dimensions: BaseExportDimensions
transparent: boolean
Return value
Data type: string

A base64 encoded data-URI that contains the image data. This URI can be used as the image source in <img src="">.

Parameters
pieId: string | Array<string>
offset: number
count: number
Return value
Data type: this
suspendPaint: (): void
Inherited from: BaseApi
Experimental property - the API might not be stable and is subject to change.

Suspends the animation of the chart until resumePaint() is called.

Data type: this
updateSize: (): this
Inherited from: BaseApi

Call when the container size has been changed to update the chart.

Return value
Data type: this
updateStyle: (): void
