HCBoostOptions class

(Highcharts, Highstock) Options for the Boost module. The Boost module allows certain series types to be rendered by WebGL instead of the default SVG. This allows hundreds of thousands of data points to be rendered in milliseconds. In addition to the WebGL rendering it saves time by skipping process

Properties

allowForce bool?
(Highcharts, Highstock) The chart will be boosted, if one of the series crosses its threshold and all the series in the chart can be boosted.
final
chunkSize num?
(Highcharts, Highstock) The number of points processed per frame when building the k-d tree for boosted series. Lower values improve responsiveness but increase the time it takes to build the tree.
final
debug HCBoostDebugOptions?
(Highcharts, Highstock) Debugging options for boost. Useful for benchmarking, and general timing.
final
enabled bool?
(Highcharts, Highstock) Enable or disable boost on a chart.
final
hashCode int
The hash code for this object.
no setterinherited
pixelRatio num?
(Highcharts, Highstock) The pixel ratio for the WebGL content. If 0, the window.devicePixelRatio is used. This ensures sharp graphics on high DPI displays like Apple's Retina, as well as when a page is zoomed.
final
runtimeType Type
A representation of the runtime type of the object.
no setterinherited
seriesThreshold num?
(Highcharts, Highstock) Set the series threshold for when the boost should kick in globally.
final
useGPUTranslations bool?
(Highcharts, Highstock) Enable or disable GPU translations. GPU translations are faster than doing the translation in JavaScript.
final
usePreallocated bool?
(Highcharts, Highstock) Enable or disable pre-allocation of vertex buffers.
final
