Flag that indicates whether the Attachable should be hidden or not, when its respective Entry is clicked.
By default, entries are assigned a smooth looking gradient based on the component color. If this flag is true, then this is skipped, and exact component solid fill is used instead.
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.

let axisX = chart.getDefaultAxisX()
// Dispose Chart, and remove all references so that they can be garbage-collected.
chart.dispose()

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.
Get shape of points.
This is defined upon creation of series, and cannot be changed afterwards.

Optional easing: AnimationEasingType of easing for animation or undefined to disable animations
Optional duration: numberCustom duration for animation in milliseconds.
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.
Configure whether cursors should pick on this particular series or not.
// Example, prevent chart auto cursor from snapping to a series.
LineSeries.setCursorEnabled(false)

Beta
Set override behavior for when this series is formatted to be displayed by a cursor. This can be used to alter and expand on cursor formatting done for a specific series, either by the library's default cursor formatters or even the users own cursor formatters defined on chart level.
// Example syntax, add extra row to display a custom data property
series.setCursorFormattingOverride((hit, before) => {
if (!isHitSampleXY(hit)) return before
const customPropertyValue = data[hit.iSample].customProperty
return [...before, ['ASD', '', customPropertyValue.toFixed(3)]]
})
To use this with users own cursor formatters, you can use useCursorFormatterSeriesOverride:
// Example syntax, define custom cursor formatting with support for series overrides
chart.setCursorFormatting((_, __, hits) => {
return [
[hits[0].axisX.formatValue(hits[0].x)],
...hits.map((hit) => useCursorFormatterSeriesOverride(hit, [['Y:', '', hit.axisY.formatValue(hit.y)]])).flat(),
]
})

Set fill style of the Polygon that represents the shape of the Series.
Example use:
// Create a new style
SpiderSeries.setFillStyle(new SolidFill({ color: ColorHEX('#F00') }))
// Change transparency
SpiderSeries.setFillStyle((solidFill) => solidFill.setA(80))
// Set hidden
SpiderSeries.setFillStyle(emptyFill)
Series itself for fluent interface.
FillStyle which has to be used for recoloring or mutator to modify existing one.
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.
Released as beta feature in v5.2.0 feature may still change according to user feedback and experiences.

Set point fill style of Series. Use IndividualPointFill object to enable individual coloring of points.
