Modifier and Type	Method and Description
`HandlerRegistration`	`addHandler(EventHandler handler, EventType type)` Adds this handler to the widget.
`void`	`checkAxes(Axis... axes)` Checks if axes, requested to be stored, are an acceptable type or amount. If a axis type or the amount of axes are not consistent for the chart, a `IllegalArgumentException` will be thrown.
`void`	`checkDatasets(Dataset... datasets)` Checks if datasets, requested to be stored, are an acceptable type or amount. If a dataset type or the amount of datasets are not consistent for the chart, a `IllegalArgumentException` will be thrown.
`void`	`createAndSetTimer(ChartTimerTask task, int interval)` Creates a `CTimer` instance inside chart. It can be created only once during the life cycle of the chart.
`void`	`destroy()` Use this to destroy any chart instances that are created.
`void`	`draw()` Draws the chart
`void`	`fireEvent(Event event)` Fires the event to the handlers.
`List<ActiveDatasetElement>`	`getActiveElements()` Returns the active (hovered) elements for the chart.
`Type`	`getBaseType()` Returns the base type of chart that in case of `ChartType` is the same of `IsChart.getType()` otherwise, in case the type of the chart is a `ControllerType` is the chart type extension if there is or `null`.
`Canvas`	`getCanvas()` Returns the canvas element used to draw the chart.
`C`	`getChart()` Returns the chart instance, wrapped by this GWT widget.
`Div`	`getChartElement()` Gets a handle to the object's underlying DOM element.

`IsDefaultScaledOptions`	`getDefaultChartOptions()` Returns the default options created based on chart type.
`DatasetReference`	`getElementAtEvent(BaseNativeEvent event)` Calling on your chart instance passing an argument of an event, will return the single element at the event position. If there are multiple items within range, only the first is returned.
`List<DatasetReference>`	`getElementsAtEvent(BaseNativeEvent event)` Looks for the element under the event point, then returns all elements at the same data index. Calling it on your chart instance passing an argument of an event, will return the point elements that are at that the same position of that event.
`int`	`getHandlerCount(EventType type)` Returns the amount of handlers for a specific event type.
`String`	`getId()` Returns the ID of chart. It could be considered as chart unique ID.
`CursorType`	`getInitialCursor()` Returns the initial cursor of the chart.

`IsDefaultScaledOptions`	`getWholeOptions()` Returns the default options by a chart instance, merging global, chart type global and chart options.
`void`	`hide(int datasetIndex)` Sets the visibility for the given dataset to false. Updates the chart and animates the dataset with 'hide' mode. This animation can be configured under the hide key in animation options.
`void`	`hide(int datasetIndex, int dataIndex)` Sets the hidden flag of that element index to `true` and updates the chart.
`boolean`	`isChartAttached()` Returns `true` whether this chart is currently attached to the browser's document.
`boolean`	`isDatasetVisible(int index)` Looks for the dataset if it's visible or not, selected by index.
`boolean`	`isDataVisible(int index)` Returns the stored visibility state of an data index for all datasets.
`boolean`	`isDestroyOnDetach()` Returns `true` if the chart is configured to be destroyed on the attach of DIV element, otherwise `false`.

`void`	`removeCanvasPreventDefault()` Remove the registration of prevent default mouse listener from canvas. This is necessary when you will add your mouse down listener.
`void`	`render()` Triggers a redraw of all chart elements. Note, this does not update elements for new data.

`void`	`resetActiveElements()` Resets the active (hovered) elements for the chart.
`void`	`resetTooltipActiveElements()` Resets the active tooltip elements for the chart.
`void`	`resize()` Use this to manually resize the canvas element.
`void`	`resize(int width, int height)` Use this to manually resize the canvas element. This is run each time the canvas container is resized, but can be called this method manually if you change the size of the canvas nodes container element.

`void`	`update()` Triggers an update of the chart. This can be safely called after updating the data object. This will update all scales, legends, and then re-render the chart.
`void`	`update(TransitionKey mode)` Triggers an update of the chart. This can be safely called after updating the data object. This will update all scales, legends, and then re-render the chart. A config object can be provided with additional configuration for the update process. This is useful when update is manually called inside an event handler and some different animation is desired.
