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 the Series.
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.

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.
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
RectangleSeries.setCursorResultTableFormatter((tableBuilder, series, figure) => {
const rectangleDimensions = figure.getDimensionsTwoPoints()
return tableBuilder
.addRow(`Pointing at`, '', series.getName())
.addRow(`X1:`, '', rectangleDimensions.x1)
.addRow(`X2:`, '', rectangleDimensions.x2)
.addRow(`Y1:`, '', rectangleDimensions.y1)
.addRow(`Y2:`, '', rectangleDimensions.y2)
})
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.
RectangleSeries.setCursorResultTableFormatter((tableBuilder, series, figure) => {
// 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
})
Default Axis formatting can be referenced by using formatValue method.
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.
Figure Series receive two extra parameters:
series | reference to the series itself.figure | reference to the pointed figure.
This type is generic - for example, for RectangleSeries it is of type RectangleFigure.Related API:
Object itself
Function which builds ResultTable content.
Set style for all figures of series. NOTE: Because the function is applied for each figure added, it is not advised to create any objects inside the function. Instead they should be previously cached and later referred to.
Example usage:
// Explicit style
// The type of 'figure' is equal to type parameter: FigureType
SimpleFigureSeries.setDefaultStyle((figure) => ...)
Object itself
Styler function that is applied to all existing and newly added segments
Configure draw order of the series.
The drawing order of series inside same chart can be configured by configuring their seriesDrawOrderIndex.
This is a simple number that indicates which series is drawn first, and which last.
The values can be any JS number, even a decimal. Higher number results in series being drawn closer to the top.
By default, each series is assigned a running counter starting from 0 and increasing by 1 for each series.
// Example, create 2 series and configure them to be drawn in reverse order.
const series1 = ChartXY.addLineSeries()
.setDrawOrder({ seriesDrawOrderIndex: 1 })
const series2 = ChartXY.addLineSeries()
.setDrawOrder({ seriesDrawOrderIndex: 0 })
// Example, ensure a series is drawn above other series.
SeriesXY.setDrawOrder({ seriesDrawOrderIndex: 1000 })
Object itself.
Object with seriesDrawOrderIndex property.
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 element visibility.
Object itself.
true when element should be visible and false when element should be hidden.
