chart.streaming

Configuration Structure

chart: {
  streaming: { ... },
    enabled: boolean,
    maxPoints: number,
}

The streaming options bound memory for long-running real-time feeds. When enabled, appendData() trims each series automatically so an always-on feed does not grow the data array without limit. The constant-velocity scroll animation for windowed updates is separate and needs no opt-in: any update that continues the previous window (appendData, or a shifted fixed-length updateSeries) translates smoothly. See the Real-time charts guide. It is part of the chart configuration.

enabled

chart.streaming.enabled
Default: false

Turn on automatic memory bounding for appendData().

maxPoints

chart.streaming.maxPoints

Maximum points kept per series by appendData(). When unset, the limit is derived from xaxis.range (if that is set); otherwise no trimming occurs.
