Gets or sets the name of the property of the data item that contains the chart value.
The binding property is used to calculate the size of the node as compared to other node values. The property should contain numeric data.
Gets or sets the name of the property containing name of the data item. The bindingName property is used to show name of the node. It should be an array or a string.
Gets or sets the name of the property (or properties) used to generate child items in hierarchical data.
Set this property to a string to specify the name of the property that
contains an item's child items (e.g. 'items'
).
Set this property to an array containing the names of the properties
that contain child items at each level, when the items are child items
at different levels with different names
(e.g. [ 'accounts', 'checks', 'earnings' ]
).
Gets the ICollectionView object that contains the chart data.
Gets or sets the DataLabel of the treemap.
Gets or sets the text displayed in the chart footer.
Gets or sets the style of the chart footer.
Angular (EventEmitter) version of the Wijmo gotFocus event for programmatic access. Use this event name if you want to subscribe to the Angular version of the event in code. In template bindings use the conventional gotFocus Wijmo event name.
Gets or sets the text displayed in the chart header.
Gets or sets the style of the chart header.
Gets the DOM element that is hosting the control.
This event is triggered after the component has been initialized by Angular, that is all bound properties have been assigned and child components (if any) have been initialized.
Angular (EventEmitter) version of the Wijmo invalidInput event for programmatic access. Use this event name if you want to subscribe to the Angular version of the event in code. In template bindings use the conventional invalidInput Wijmo event name.
Gets or sets a value that determines whether the control is disabled.
Disabled controls cannot get mouse or keyboard events.
Indicates whether the component has been initialized by Angular. Changes its value from false to true right before triggering the initialized event.
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 item formatter function that allows you to customize the appearance of the chart elements.
If specified, the function should take three parameters: the chart's IRenderEngine responsible for rendering elements on the chart, a HitTestInfo parameter that describes the element being rendered, and a function that provides the default rendering for the item.
For example:
itemFormatter: function (engine, hitTestInfo, defaultRenderer) { var ht = hitTestInfo, binding = 'downloads'; // check that this is the right series/element if (ht.series.binding == binding && ht.pointIndex > 0 && ht.chartElement == ChartElement.SeriesSymbol) { // get current and previous values var chart = ht.series.chart, items = chart.collectionView.items, valNow = items[ht.pointIndex][binding], valPrev = items[ht.pointIndex - 1][binding]; // add line if value is increasing if (valNow > valPrev) { var pt1 = chart.dataToPoint(ht.pointIndex, valNow), pt2 = chart.dataToPoint(ht.pointIndex - 1, valPrev); engine.drawLine(pt1.x, pt1.y, pt2.x, pt2.y, null, { stroke: 'gold', strokeWidth: 6 }); } } // render element as usual defaultRenderer(); }
{@sample: Chart/LineArea/CustomLineSegments/purejs Example}
Gets or sets the array or ICollectionView object that contains the data used to create the chart.
Angular (EventEmitter) version of the Wijmo itemsSourceChanged event for programmatic access. Use this event name if you want to subscribe to the Angular version of the event in code. In template bindings use the conventional itemsSourceChanged Wijmo event name.
Angular (EventEmitter) version of the Wijmo itemsSourceChanging event for programmatic access. Use this event name if you want to subscribe to the Angular version of the event in code. In template bindings use the conventional itemsSourceChanging Wijmo event name.
Gets or sets the chart legend.
Angular (EventEmitter) version of the Wijmo lostFocus event for programmatic access. Use this event name if you want to subscribe to the Angular version of the event in code. In template bindings use the conventional lostFocus Wijmo event name.
Gets or sets the maximum number of node levels to show in the current view. These levels are flattened into the current plane. If a treemap has more levels than this value, user has to move up and down.
Gets or sets an array of default colors to be used in a treemap.
The array contains strings that represent CSS colors. For example:
// use colors specified by name chart.palette = ['red', 'green', 'blue']; // or use colors specified as rgba-values chart.palette = [ 'rgba(255,0,0,1)', 'rgba(255,0,0,0.8)', 'rgba(255,0,0,0.6)', 'rgba(255,0,0,0.4)'];
Or contains titleColor, maxColor, minColor separately. For example:
chart.palette = [{ titleColor: '#00277d', maxColor: 'rgba(0,39,125,0.7)', minColor: 'rgba(168,187,230,0.7)' }, { titleColor: '#7d1f00', maxColor: 'rgba(125,21,0,0.7)', minColor: 'rgba(230,183,168,0.7)' }, { titleColor: '#007d27', maxColor: 'rgba(0,125,39,0.7)', minColor: 'rgba(168,230,188,0.7)' }];
Gets or sets the plot margin in pixels.
The plot margin represents the area between the edges of the control and the plot area.
By default, this value is calculated automatically based on the space required by the axis labels, but you can override it if you want to control the precise position of the plot area within the control (for example, when aligning multiple chart controls on a page).
You may set this property to a numeric value or to a CSS-style margin specification. For example:
// set the plot margin to 20 pixels on all sides chart.plotMargin = 20; // set the plot margin for top, right, bottom, left sides chart.plotMargin = '10 15 20 25'; // set the plot margin for top/bottom (10px) and left/right (20px) chart.plotMargin = '10 20';

Angular (EventEmitter) version of the Wijmo refreshing event for programmatic access. Use this event name if you want to subscribe to the Angular version of the event in code. In template bindings use the conventional refreshing Wijmo event name.
Angular (EventEmitter) version of the Wijmo rendered event for programmatic access. Use this event name if you want to subscribe to the Angular version of the event in code. In template bindings use the conventional rendered Wijmo event name.
Angular (EventEmitter) version of the Wijmo rendering event for programmatic access. Use this event name if you want to subscribe to the Angular version of the event in code. In template bindings use the conventional rendering Wijmo event name.
Gets a value indicating whether the control is hosted in an element with right-to-left layout.
Angular (EventEmitter) version of the Wijmo selectionChanged event for programmatic access. Use this event name if you want to subscribe to the Angular version of the event in code. In template bindings use the conventional selectionChanged Wijmo event name.
The selectionMode doesn't work in TreeMap control.
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.
Gets the chart's Tooltip.
Gets or sets the TreeMapType of the treemap.
Defines a name of a property represented by [(ngModel)] directive (if specified). Default value is ''.
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');
@param classNames Names of classes to add to the control's host element. @param template An HTML string that defines the control template. @param parts A dictionary of part variables and their names. @param namePart Name of the part to be named after the host element. This determines how the control submits data when used in forms.
Suspends notifications until the next call to endUpdate.
Checks whether this control contains the focused element.
If you create a custom component inherited from a Wijmo component, you can override this method and perform necessary initializations that you usually do in a class constructor. This method is called in the last line of a Wijmo component constructor and allows you to not declare your custom component's constructor at all, thus preventing you from a necessity to maintain constructor parameters and keep them in synch with Wijmo component's constructor parameters.
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.
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.
Resumes notifications suspended by calls to beginUpdate.
Sets the focus to this control.
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).
Determines whether an object has a property with the specified name.
A property name.
Gets a HitTestInfo object with information about the specified point.
The point to investigate, in window coordinates.
Y coordinate of the point (if the first parameter is a number).
A HitTestInfo object containing information about the point.
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.
Invalidates the control causing an asynchronous refresh.
Whether to update the control layout as well as the content.
Determines whether an object exists in another object's prototype chain.
Another object whose prototype chain is to be checked.
Raises the invalidInput event.
If the event handler cancels the event, the control will keep the invalid input and the focus.
Raises the itemsSourceChanged event.
Raises the itemsSourceChanging event.
CancelEventArgs that contains the event data.
True if the event was not canceled.
Raises the refreshing event.
Raises the rendered event.
The RenderEventArgs object used to render the chart.
Raises the rendering event.
The RenderEventArgs object used to render the chart.
Raises the selectionChanged event.
Converts page coordinates to control coordinates.
The point of page coordinates or x value of page coordinates.
The y value of page coordinates. Its value should be a number, if pt is a number type. However, the y parameter is optional when pt is Point type.
Determines whether a specified property is enumerable.
A property name.
Refreshes the chart.
A value indicating whether to update the control layout as well as the content.
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.
The number of listeners removed.
Saves the chart to an image data url.
NOTE: This method does not work in IE browsers. If you require IE support,
add the flex-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.
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.
Saves the chart to a data url as SVG image.
A function to be called after data url is generated. The function gets passed the data url as its argument.
Whether to include CSS styles to SVG image.
Saves the chart to an SVG image file.
The filename for the exported image file including extension.
Whether to include CSS styles to SVG image.
Returns a date converted to a string using the current locale.
Returns a string representation of an object.
Returns the primitive value of the specified object.
Disposes of all Wijmo controls contained in an HTML element.
Container element.
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').
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 Control.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.
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.
Occurs when the control gets the focus.
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 chart has been bound to a new items source.
Occurs before the chart is bound to a new items source.
Occurs when the control loses the focus.
Occurs after the control has refreshed its contents.
Occurs when the control is about to refresh its contents.
Occurs after the chart finishes rendering.
Occurs before the chart starts rendering data.
Occurs after the selection changes, whether programmatically or when the user clicks the chart. This is useful, for example, when you want to update details in a textbox showing the current selection.
