Series Labels Color is not Transparent


Background color of RadHtmlChart series labels is no longer transparent, but takes the color of the series item.


To get transparent colors back, you can change the chart options via the underlying Kendo Chart Widget API (see also individual series label and default label).

    function OnLoad(sender) {
        var kChart = sender.get_kendoWidget();
        var kChartOptions = kChart.options;
        kChartOptions.seriesDefaults.labels.background = "transparent";
<telerik:RadHtmlChart runat="server" ID="rhc1">
    <ClientEvents OnLoad="OnLoad" />
                    <telerik:SeriesItem  YValue="1" Name="first"/>
                    <telerik:SeriesItem  YValue="2" Name="second"/>
