Provides visual representations of wijmo.olap pivot tables.
To use the control, set its itemsSource property to an instance of a PivotPanel control or to a PivotEngine.
constructor(element: any, options?: any): PivotChart
Initializes a new instance of the PivotChart class.
The DOM element that will host the control, or a CSS selector for the host element (e.g. '#theCtrl').
JavaScript object containing initialization data for the control.
Gets or sets the type of chart to create.
The default value for this property is PivotChartType.Column.
Gets or sets the style of the chart header.
Gets the DOM element that is hosting the control.
Gets or sets a value that determines whether the control is disabled.
Disabled controls cannot get mouse or keyboard events.
Gets a value that indicates whether the control is currently handling a touch event.
Gets a value that indicates whether the control is currently being updated.
Gets or sets the PivotEngine or PivotPanel that provides data for this PivotChart.
Gets or sets a value that determines whether and where the legend appears in relation to the plot area.
The default value for this property is Position.Right.
Gets or sets the maximum number of points to be shown in each series.
The default value for this property is 100 points.
Gets or sets the maximum number of data series to be shown in the chart.
The default value for this property is 100 series.
Gets a value indicating whether the control is hosted in an element with right-to-left layout.
Gets or sets a value that determines whether the chart should group axis annotations for grouped data.
The default value for this property is true.
Gets or sets a value that determines whether the chart should include a legend.
The default value for this property is LegendVisibility.Always.
Gets or sets a value that determines whether the chart should include a title.
The default value for this property is true.
Gets or sets a value that determines whether the chart should include only totals.
If showTotals is true and the view has Column Fields, then the chart will show column totals instead of individual values.
The default value for this property is false.
Gets or sets a value that determines whether and how the series objects are stacked.
The default value for this property is Stacking.None.
Gets or sets a value of the **tabindex** attribute associated with the control.
**tabindex** attribute value can be defined statically for a Wijmo control by specifying it on the control's host HTML element. But this value can't be changed later during application lifecycle, because Wijmo controls have complex structure, and the control may need to propagate this attribute value to its internal element to work properly.
Because of this, to read or change control's **tabindex** dynamically, you should do it using this property.
addEventListener(target: EventTarget, type: string, fn: any, capture?: boolean, passive?: boolean): void
Adds an event listener to an element owned by this Control.
The control keeps a list of attached listeners and their handlers, making it easier to remove them when the control is disposed (see the dispose and removeEventListener methods).
Failing to remove event listeners may cause memory leaks.
The passive parameter is set to false by default, which means the event handler may call event.preventDefault(). If you are adding passive handlers to touch or wheel events, setting this parameter to true will improve application performance.
For details on passive event listeners, please see Improving scrolling performance with passive listeners.
Target element for the event.
String that specifies the event.
Function to execute when the event occurs.
Whether the listener should be handled by the control before it is handled by the target element.
Indicates that the handler will never call preventDefault().
applyTemplate(classNames: string, template: string, parts: Object, namePart?: string): HTMLElement
Applies the template to a new instance of a control, and returns the root element.
This method should be called by constructors of templated controls. Therefore, this method is not available. It is responsible for binding the template parts to the corresponding control members.
For example, the code below applies a template to an instance of an InputNumber control. The template must contain elements with the 'wj-part' attribute set to 'input', 'btn-inc', and 'btn-dec'. The control members '_tbx', '_btnUp', and '_btnDn' will be assigned references to these elements.
this.applyTemplate('wj-control wj-inputnumber', templateString, {
_tbx: 'input',
_btnUp: 'btn-inc',
_btnDn: 'btn-dec'
}, 'input');
```
Names of classes to add to the control's host element.
An HTML string that defines the control template.
A dictionary of part variables and their names.
Name of the part to be named after the host element. This determines how the control submits data when used in forms.
beginUpdate(): void
Suspends notifications until the next call to endUpdate.
deferUpdate(fn: Function): void
Executes a function within a beginUpdate/endUpdate block.
The control will not be updated until the function has been executed. This method ensures endUpdate is called even if the function throws an exception.
Function to be executed.
dispose(): void
Disposes of the control by removing its association with the host element.
The dispose method automatically removes any event listeners added with the addEventListener method.
Calling the dispose method is important in applications that create and remove controls dynamically. Failing to dispose of the controls may cause memory leaks.
disposeAll(e?: HTMLElement): void
Disposes of all Wijmo controls contained in an HTML element.
Container element.
endUpdate(): void
Resumes notifications suspended by calls to beginUpdate.
getControl(element: any): Control
Gets the control that is hosted in a given DOM element.
The DOM element that hosts the control, or a CSS selector for the host element (e.g. '#theCtrl').
getTemplate(): string
Gets the HTML template used to create instances of the control.
This method traverses up the class hierarchy to find the nearest ancestor that specifies a control template. For example, if you specify a prototype for the ComboBox control, which does not specify a template, it will override the template defined by the DropDown base class (the nearest ancestor that does specify a template).
initialize(options: any): void
Initializes the control by copying the properties from a given object.
This method allows you to initialize controls using plain data objects instead of setting the value of each property in code.
For example:
grid.initialize({
itemsSource: myList,
autoGenerateColumns: false,
columns: [
{ binding: 'id', header: 'Code', width: 130 },
{ binding: 'name', header: 'Name', width: 60 }
]
});
// is equivalent to
grid.itemsSource = myList;
grid.autoGenerateColumns = false;
// etc.
The initialization data is type-checked as it is applied. If the initialization object contains unknown property names or invalid data types, this method will throw.
Object that contains the initialization data.
invalidate(fullUpdate?: boolean): void
Invalidates the control causing an asynchronous refresh.
Whether to update the control layout as well as the content.
invalidateAll(e?: HTMLElement): void
Invalidates all Wijmo controls contained in an HTML element.
Use this method when your application has dynamic panels that change the control's visibility or dimensions. For example, splitters, accordions, and tab controls usually change the visibility of its content elements. In this case, failing to notify the controls contained in the element may cause them to stop working properly.
If this happens, you must handle the appropriate event in the dynamic container and call the invalidateAll method so the contained Wijmo controls will update their layout information properly.
Container element. If set to null, all Wijmo controls on the page will be invalidated.
onGotFocus(e?: EventArgs): void
Raises the gotFocus event.
onInvalidInput(e: CancelEventArgs): void
Raises the invalidInput event.
If the event handler cancels the event, the control will keep the invalid input and the focus.
onLostFocus(e?: EventArgs): void
Raises the lostFocus event.
onRefreshed(e?: EventArgs): void
Raises the refreshed event.
onRefreshing(e?: EventArgs): void
Raises the refreshing event.
refresh(fullUpdate?: boolean): void
Refreshes the control.
Whether to update the control layout as well as the content.
refreshAll(e?: HTMLElement): void
Refreshes all Wijmo controls contained in an HTML element.
This method is similar to invalidateAll, except the controls are updated immediately rather than after an interval.
Container element. If set to null, all Wijmo controls on the page will be invalidated.
removeEventListener(target?: EventTarget, type?: string, fn?: any, capture?: boolean): number
Removes one or more event listeners attached to elements owned by this Control.
Target element for the event. If null, removes listeners attached to all targets.
String that specifies the event. If null, removes listeners attached to all events.
Handler to remove. If null, removes all handlers.
Whether the listener is capturing. If null, removes capturing and non-capturing listeners.
saveImageToDataUrl(format: ImageFormat, done: Function): void
Saves the chart to an image data url.
NOTE: This method does not work in IE browsers. If you require IE support, add the wijmo.chart.render module to the page.
The ImageFormat for the exported image.
A function to be called after data url is generated. The function gets passed the data url as its argument.
saveImageToFile(filename: string): void
Saves the chart to an image file.
NOTE: This method does not work in IE browsers. If you require IE support, add the wijmo.chart.render module to the page.
The filename for the exported image file including extension. Supported types are PNG, JPEG and SVG.
Occurs when invalid input is detected.
Invalid input may occur when the user types or pastes a value that cannot be converted to the proper type, or a value that is outside the valid range.
If the event handler cancels the event, the control will retain the invalid content and the focus, so users can correct the error.
If the event is not canceled, the control will ignore the invalid input and will retain the original content.
Occurs after the control has refreshed its contents.
