How to remove outline or stroke from ChartSeriesMarkers in Telerik Chart?

Guys, I'm trying to remove marker outline i.e. stroke in the Telerik Chart. But I'm not seeing any way to do this.

Problem with outline (stroke): For the large point data and very near data, telerik chart is ploting data point as linear graph and looks good. But when do moveout on legend it's showing only last point other getting blank:

1. Without mouse hover
   
2. With mouse hover on legend
   

I tried to remove stroke by css:

<style>
    /* See also component isolated css file if present. */
    div svg circle {
        stroke: #000000;
        stroke-width: 0px;
    }
</style>

But I want to do this from chart control:

<ChartSeriesMarkers>
    <ChartSeriesMarkersBorder Width="0"></ChartSeriesMarkersBorder>
</ChartSeriesMarkers>

Anyone has any idea?
