1000 Points Threshold

{{ZKChartsEssentialsPageHeader}}



If the data points (<javadoc directory="zkcharts">org.zkoss.chart.Point</javadoc>) of a series are not Number and neither array, there is a 1000-points limitation for rendering a series. If a series contains more than 1000 points, ZK Charts won't render that series.

Please run '''turboThreshold.zul''' in the example project, and you will see no series rendered after you click "add 1000 non-number points" button.

If you open chrome developer tool / console tab, you will see the error message below:

  Highcharts error #12: [https://www.highcharts.com/errors/12 www.highcharts.com/errors/12]

= Solution =
* Put numeric data in <code>Point</code>.
<code>series.add(Number)</code> or <code>addPoint(double)</code>
* Increase turbo threshold
<code>chart.getPlotOptions().getSeries().setTurboThreshold(aLargerValue)</code>
* disable threhshold
<code>chart.getPlotOptions().getSeries().setTurboThreshold(0)</code>
