[Solved]-Proper way to remove all series data from a highcharts chart?-Highcharts

I found the working solution. Try this:

for (var i = 0; i < chart.series.length; i++) {
   chart.series[0].remove();
}
chart.redraw();

It will completely remove all series.

It may just be a simple matter of telling the chart to redraw. When you remove a series, try forcing the chart to redraw:

for (var i = 0; i < chart.series.length; i++) {
    chart.series[i].remove(true); //forces the chart to redraw
}

var seriesLength = chart.series.length; for(var i = seriesLength -1; i > -1; i--) { chart.series[i].remove(); }

You can also update and add a new series and if the new series is less than the current series then remove the series:

var hChart = $("#Chart").highcharts();

for (var i = 0; i < newSeries.length; i++) { //UPDATE-OLD/ADD-NEW SERIES
    if (hChart.series[i])
        hChart.series[i].update(newSeries[i]);
    else
        hChart.addSeries(newSeries[i]);
}

var serieslen = newSeries.length;
if (hChart.series[serieslen]) {
    var loopfrm = hChart.series.length - 1;
    for (var i = loopfrm; i >= serieslen; i--) {//REMOVE SERIES
        hChart.series[loopfrm].remove();
    }
}

The reason for (var i = 0; i < chart.series.length; i++) doesn't work is because you're modifying the array while you're looping over it. To get around this, you can iterate over the array from right to left, so when you remove an element, the index of the array will still point to the last item in the array.

Using lodash's forEachRight, you can do:

_.forEachRight(chart.series, chartSeries => {
  chartSeries.remove(false);
});

chart.redraw();

Another way to remove all series in HighCharts with a for loop is to start from the end. Here's how to do it:

var seriesLength = chart.series.length;
for(var i = seriesLength - 1; i > -1; i--) {
    chart.series[i].remove();
}

I prefer to go this route because when using a HighStock chart, the navigator is usually the first series. I also prefer to keep a variable set to the navigator series. In that case, I'll do the following:

var seriesLength = chart.series.length;
var navigator;
for(var i = seriesLength - 1; i > -1; i--) {
    if(chart.series[i].name.toLowerCase() == 'navigator') {
        navigator = chart.series[i];
    } else {
        chart.series[i].remove();
    }
}

Now I can easily set the navigator series.

The following way the chart will not redraw every iteration.
So you'll get a better performance.

while( chart.series.length > 0 ) {
    chart.series[0].remove( false );
}

chart.redraw();
