Disabling turboThreshold in Boost mode works, but still shows Error #12

[nbrown96]

Expected behaviour

When plotOptions.series.turboThreshold is set to 0 and boost mode is enabled, a scatter plot with many points in the format {x: number, y: number, color: rgba string} will display without error.
My understanding is that this is the best (or maybe the only) way to specify colors for individual scatter plot points.

Actual behaviour

The chart works fine, but Highcharts Error #12 shows in the console, which clutters the console.

Hi @nbrown96

Thanks for reporting the issue, but turboThreshold does not work in the boost module, see our docs: https://api.highcharts.com/highcharts/series.line.turboThreshold and error message:

This error occurs if the series.data option contains object configurations and the number of points exceeds the turboThreshold. It can be fixed by either setting turboThreshold to a higher value, or changing the point configurations to numbers or arrays.

In boost mode, turbo mode is always on, which means only array of numbers or two dimensional arrays are allowed.

Regarding this:

My understanding is that this is the best (or maybe the only) way to specify colors for individual scatter plot points.

This is the best way. Alternative solution is to split your dataset into multiple series, linked to the main series. Each series can use separate color.

You can also ignore the error:

Highcharts.addEvent(Highcharts.Chart, 'displayError', function (event) {
	if (event.code === 12) {
		event.preventDefault();
	}
});
