Properties

Static asyncLabels

asyncLabels: boolean = false
deprecated

This functionality has been removed. useNativeText: true provides much greater performance benefit.

Static createSuspended

createSuspended: boolean = false

Defines if newly created charts should be rendered as soon as possible after initialization. Setting to true will require surfaces to be "resumed" in order to perform actual rendering.

Static enableResampling

enableResampling: boolean = true

Turn on/off resampling

Static nativeFontTimeout

nativeFontTimeout: number = 2000

Time in ms to retry loading a native font. If you need to load a large font over a potentially slow connection await sciChartSurface.registerFont

Static performanceWarnings

performanceWarnings: boolean = true

Turn on/off warnings to optimize performance

Static useNativeText

useNativeText: boolean = false

Experimental - set true to use native text for axes and titles. Not all text features currently supported

Static useSharedCache

useSharedCache: boolean = false

Set this true to allow reuse of label textures across different axes and different charts

Static wasmBufferSizesKb

wasmBufferSizesKb: number = 1024 * 8

For 2D charts a number of buffers are created to process data. Buffer size by default grows with usage and caps out at 8,192kb. A total of 10 buffers are created for different scenarios. When SciChartSurface.create() is used this results in a maximum of 80MB memory as a static overhead for the application. When SciChartSurface.createSingle() is used this results in up to 80MB memory per chart as a static overhead. Lowering this number to 2048kb (or 1024kb) will reduce memory usage for the SciChart 2D Engine but may impact chart drawing performance.

remarks

This property needs to be set before charts created and cannot be dynamically adjusted after that. Do not set lower than 1024kb or higher than 32MB (1024 x 32). Values outside this range will be clamped

Static watermarkPosition

watermarkPosition: EWatermarkPosition = EWatermarkPosition.BottomLeft

The default position of the watermark for trials

Static watermarkRelativeToCanvas

watermarkRelativeToCanvas: boolean = false

For 2D charts the watermark is normally positioned within the series area. Set this true to place it relative to the overall canvas.
