HTMLGraph: LabelsAppearance empty when value is zero

[Blas]

Hi, 

Is it possible to show an empty label when the column has a zero value? I've tried DataFormatString="{0:#}" but it doesn't work.

<telerik:RadHtmlChart runat="server" ID="RadHtmlChart1" Height="550px" Style="left: 10px; right: 10px;"  >
    <PlotArea>

        <Series>
            <telerik:ColumnSeries DataFieldY="AcumuladoAnt"  Name="<%$Resources:htmlChartAnterior %>" >
               <LabelsAppearance DataFormatString="{0:#}"></LabelsAppearance>

            </telerik:ColumnSeries>
            <telerik:ColumnSeries DataFieldY="AcumuladoAct" Name="<%$Resources:htmlChartActual %>">
                 <LabelsAppearance DataFormatString="{0:#}" ></LabelsAppearance>
            </telerik:ColumnSeries>
        </Series>
        <XAxis DataLabelsField="Mes">
            <TitleAppearance Text="<%$Resources:htmlChartMes %>">
                <TextStyle Margin="20" />
            </TitleAppearance>
            <MajorGridLines Visible="false" />
            <MinorGridLines Visible="false" />
        </XAxis>
        <YAxis>
            <TitleAppearance Text="<%$Resources:htmlChartImporte %>">
                <TextStyle Margin="20" />
            </TitleAppearance>

            <MinorGridLines Visible="false" />
        </YAxis>
    </PlotArea>
    <ChartTitle Text="<%$Resources:htmlChartTitle %>">
    </ChartTitle>
    <Legend>
        <Appearance BackgroundColor="White" Position="Bottom">
            <TextStyle Bold="false" FontFamily="Helvetica" Italic="false" Color="Black" FontSize="12"
                Margin="0" Padding="0" />
        </Appearance>
    </Legend>
</telerik:RadHtmlChart>

Here is a screenshot of the graph.

Thank you

Hi Roberto,

Can you try to upgrade your version of Telerik UI to the latest official one - 2014.1.225 and then tell us whether the labels for zero items are displayed?

Hi Danail

It's the version I have, and I didn't noticed this behavior before I've installed it.

I'm seeing something very similar on the latest version if one of the dates on the xaxis does not have values for any of the three column series in the chart.
