    is it possible that displaying gaps is not working any more for the new release Q3 2013?
    I took the example you provided under
    http://www.telerik.com/help/aspnet-ajax/htmlchart-types-scatterline-chart.html and

    and for me it is not working.
    The gaps are not visible but instead the line is interpolated.
    Always giving me the attached result.

    My Code:
    <asp:Content ID="Content1" ContentPlaceHolderID="MainContentPlace" runat="server">
        <telerik:RadScriptManager ID="TrsmScriptManager" runat="server">
        <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
        <telerik:RadHtmlChart runat="server" ID="ScatterLineChart1" Transitions="true">
                    <telerik:ScatterLineSeries Name="0.8C" MissingValues="Gap">
                        <LabelsAppearance DataFormatString="{1}% in {0} minutes" Position="Below" />
                        <MarkersAppearance MarkersType="Circle" />
                            <telerik:ScatterSeriesItem X="10" Y="10" />
                            <telerik:ScatterSeriesItem X="15" Y="20" />
                            <telerik:ScatterSeriesItem />
                            <telerik:ScatterSeriesItem X="32" Y="40" />
                            <telerik:ScatterSeriesItem X="43" Y="50" />
                            <telerik:ScatterSeriesItem X="55" Y="60" />
                            <telerik:ScatterSeriesItem X="60" Y="70" />
                    <telerik:ScatterLineSeries Name="1.6C">
                        <LabelsAppearance DataFormatString="{1}% in {0} minutes" Position="Below" />
                        <MarkersAppearance MarkersType="Square" />
                            <telerik:ScatterSeriesItem X="10" Y="40" />
                            <telerik:ScatterSeriesItem X="17" Y="50" />
                            <telerik:ScatterSeriesItem X="18" Y="70" />
                            <telerik:ScatterSeriesItem X="35" Y="90" />
                            <telerik:ScatterSeriesItem X="47" Y="95" />
                            <telerik:ScatterSeriesItem X="60" Y="100" />
                <XAxis AxisCrossingValue="0" Color="Black" MajorTickType="Outside" MinorTickType="Outside"
                    Reversed="false" MinValue="0" MaxValue="90" Step="10">
                    <LabelsAppearance DataFormatString="{0}m" RotationAngle="0" />
                    <MajorGridLines Color="#EFEFEF" Width="1" />
                    <MinorGridLines Color="#F7F7F7" Width="1" />
                    <TitleAppearance Position="Center" RotationAngle="0" Text="Time" />
                <YAxis AxisCrossingValue="0" Color="Black" MajorTickSize="1" MajorTickType="Outside"
                    MaxValue="100" MinorTickSize="1" MinorTickType="Outside" MinValue="0" Reversed="false"
                    <LabelsAppearance DataFormatString="{0}%" RotationAngle="0" />
                    <MajorGridLines Color="#EFEFEF" Width="1" />
                    <MinorGridLines Color="#F7F7F7" Width="1" />
                    <TitleAppearance Position="Center" RotationAngle="0" Text="Charge" />
            <ChartTitle Text="Charge current vs. charge time">
                <Appearance Position="Bottom" />

    Currently there is an issue with the MissingValues property of the series when it is set to "Gap". The issue has already been logged in our feedback portal here and you can monitor, comment or raise its priority by voting on it. For the time being you can use the workaround provided in the feedback item.

    It looks like this bug either never got fixed or has returned.  I am setting MissingValues="Gap" on a linechart and I am seeing all missing values drawn at zero.  Is there a true fix planned or must we use this workaround still?
