Hi Rikard, 
 
Greetings from Syncfusion. We have analyzed our query. We are already having removeSeries method to remove the series. By using this, you can remove the series one at a time. However, your requirement can be achieved as a workaround by assigning empty array to series and refresh the chart. Find the code snippet below to achieve this requirement. 
 
 
document.getElementById("remove").onclick = function () { 
        var chart = document.getElementById("container").ej2_instances[0]; 
        //Assigning empty array to series and refresh the chart 
        chart.series = []; 
        chart.refresh(); 
    } 
 
 
 
 
Hope this helps. 
 
Thanks, 
Dharani.
