Permanently destroy the component.
To fully allow Garbage-Collection to free the resources used by the component, make sure to remove any references to the component and its children in application code.

Get whether series is taken into account with automatic scrolling and fitting of attached axes.
By default, this is true for all series.
true
default, axes will take series into account in scrolling and fitting operations.
false
, axes will ignore series boundaries.
Get ResultTable Formatter.
Function which builds ResultTable content for SpiderSeries.
Get theme effect enabled on component or disabled.
A theme can specify an Effect to add extra visual oomph to chart applications, like Glow effects around data or other components.
Whether this effect is drawn above a particular component can be configured using the setEffect
method.
// Example, disable theme effect from a particular component.
Component.setEffect(false)
For the most part, theme effects are enabled by default on most components.
Theme effect is configured with effect property.
Boolean that describes whether drawing the theme effect is enabled around the component or not.

event.
This event is triggered whenever the ChartComponent is disposed.
// Example usage
lineSeries.onDispose(() => {
console.log('lineSeries was disposed')
})
lineSeries.dispose()

Set component highlight animations enabled or not. For most components this is enabled by default.
// Example usage, disable highlight animations.
component.setAnimationHighlight(false)
Object itself
Animation enabled?
Set whether series is taken into account with automatic scrolling and fitting of attached axes.
By default, this is true for all series.
By setting this to false
, any series can be removed from axis scrolling/fitting.
// Example syntax, remove series from automatic scrolling / fitting.
LineSeries.setAutoScrollingEnabled(false)
Object itself for fluent interface.
true
default, axes will take series into account in scrolling and fitting operations.
false
, axes will ignore series boundaries.
Set automatic connection of first and last data points enabled or not.
Disabled by default.
Object itself for fluent interface.
Boolean.
Configure whether cursors should pick on this particular series or not.
// Example, prevent chart auto cursor from snapping to a series.
LineSeries.setCursorEnabled(false)
Related API:
Configure formatting of Cursor ResultTable when pointing at this series.
// Example usage
PolarLineSeries.setCursorResultTableFormatter((tableBuilder, series, angleDeg, amplitude) => {
return tableBuilder
.addRow(`Pointing at`, '', series.getName())
.addRow(`Angle:`, '', angleDeg.toFixed(0) + ' deg')
.addRow(`Amplitude:`, '', amplitude.toFixed(1))
})
The general syntax of configuring ResultTable formatting is shared between all series types; You specify a callback function, which receives a TableContentBuilder. The contents of the table are then set using methods of the table builder:
// Using TableContentBuilder.
PolarLineSeries.setCursorResultTableFormatter((tableBuilder, series, angleDeg, amplitude) => {
// addRow adds a list of strings to a new row in the table. Empty strings ('') will allocate any extra horizontal space within the row.
tableBuilder
.addRow('Item 0:', '', 'Value 0')
.addRow('Item 1:', '', 'Value 1')
.addRow('Long row that highlights the idea of empty strings')
// After configuration, the table builder must be returned!
return tableBuilder
})
The additional values that are supplied to the callback function vary between different chart types,
refer to the series documentation of setCursorResultTableFormatter
to learn the exact available information.
All Polar Series
receive three extra parameters:
series
| reference to the series itself.angleDeg
| pointed data point angle as degrees.amplitude
| pointed data point amplitude.Related API:
Object itself
Function which builds ResultTable content.
Set data for PolarSeries to render as a list of PolarPoints.
Object itself for fluent interface.
List of PolarPoints.
Set theme effect enabled on component or disabled.
A theme can specify an Effect to add extra visual oomph to chart applications, like Glow effects around data or other components.
Whether this effect is drawn above a particular component can be configured using the setEffect
method.
// Example, disable theme effect from a particular component.
Component.setEffect(false)
For the most part, theme effects are enabled by default on most components.
Theme effect is configured with effect property.
Object itself.
Theme effect enabled
Set state of component highlighting.
// Example usage
component.setHighlight(true)
component.setHighlight(0.5)
If highlight animations are enabled (which is true by default), the transition will be animated. As long as the component is highlighted, the active highlight intensity will be animated continuously between 0 and the configured value. Highlight animations can be disabled with setAnimationHighlight
Object itself
Boolean or number between 0 and 1, where 1 is fully highlighted.
Set highlight on mouse hover enabled or disabled.
Mouse interactions have to be enabled on the component for this to function as expected. See setMouseInteractions for more information.
Object itself for fluent interface.
True if highlighting on mouse hover, false if no highlight on mouse hover
Set component mouse interactions enabled or disabled.
Disabling mouse interactions means that the objects below this component can be interacted through it.
Possible side-effects from disabling mouse interactions:
Object itself for fluent interface
Specifies state of mouse interactions
Sets the name of the Component updating attached LegendBox entries
Object itself
Name of the Component
Set stroke style of Series.
Example usage:
// Specified LineStyle
PolarLineSeries.setStrokeStyle(new SolidLine({ thickness: 2, fillStyle: new SolidFill({ color: ColorHEX('#F00') }) }))
// Changed thickness
PolarLineSeries.setStrokeStyle((solidLine) => solidLine.setThickness(5))
// Hidden must be done with setVisible() method, emptyLine is not supported
Chart itself
Either a LineStyle object or a function, which will be used to create a new LineStyle based on current value.
Set element visibility.
