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
Roberto
