Hello Ahmet,

The Data Navigation functionality of the chart works only with category series (i.e., area, line, column, candlestick), so that you cannot use it with numeric series like scatter, scatterline and bubble.

If you want to have an example of a Data Navigation functionality with line series you can simply replace the candlestick series in the Data Navigation help article / HtmlChart - Data Navigation online demo with line series and set the corresponding data bound property of the series - DataFieldY. For example:
ASPX:

<telerik:RadHtmlChart runat="server" ID="RadHtmlChart1" Layout="Stock" Width="800" Height="500" Skin="Default">

<Navigator Visible="true">

<RangeSelector From="2008/05/01" To="2009/09/01" />

<SelectionHint Visible="true" DataFormatString="From {0:d} to {1:d}" />

<Series>

<telerik:AreaSeries DataFieldY="DisneyClose">

</telerik:AreaSeries>

</Series>

<XAxis Color="#aaaaaa">

<LabelsAppearance>

<TextStyle Color="#666666" />

</LabelsAppearance>

</XAxis>

</Navigator>

<PlotArea>

<Series>

<telerik:LineSeries Name="Disney" DataFieldY="DisneyOpen">

</telerik:LineSeries>

</Series>

<XAxis DataLabelsField="DisneyDate" Type="Date" Name="mainAxis">

<MajorGridLines Visible="false"></MajorGridLines>

<MinorGridLines Visible="false"></MinorGridLines>

<TitleAppearance Text="Date">

</TitleAppearance>

</XAxis>

<YAxis>

<LabelsAppearance DataFormatString="{0:C}">

</LabelsAppearance>

<MajorGridLines Visible="true" Color="#efefef" Width="1"></MajorGridLines>

<MinorGridLines Visible="false"></MinorGridLines>

<TitleAppearance Text="Price">

</TitleAppearance>

</YAxis>

</PlotArea>

<ChartTitle Text="The Walt Disney Company (DIS)">

</ChartTitle>

</telerik:RadHtmlChart>

C#:

protected void Page_Load(object sender, EventArgs e)

{

RadHtmlChart1.DataSource = GetData();

RadHtmlChart1.DataBind();

}

You can find the full runnable VS example in the attached archive.

Hello Ahmet,

You can use the "#= kendo.format(\'{0:MM/dd/yyyy}\', dataItem.DATA_TIME) #" string in the template. For example:

ASPX:

<telerik:RadHtmlChart runat="server" ID="RadHtmlChart1" Width="600px" Height="400px">

<PlotArea>

<Series>

<telerik:LineSeries Name="Volume" DataFieldY="Volume">

<TooltipsAppearance Color="White">

<ClientTemplate>

Inventory <br />

Date: #= kendo.format(\'{0:dd/MMM/yyyy}\', dataItem.DATA_TIME) # <br/>

YValue: #= kendo.format(\'{0:n0}\', dataItem.Volume)#

</ClientTemplate>

</TooltipsAppearance>

<LabelsAppearance Visible="false">

</LabelsAppearance>

</telerik:LineSeries>

</Series>

<XAxis DataLabelsField="DATA_TIME">

<LabelsAppearance Step="2"></LabelsAppearance>

</XAxis>

</PlotArea>

<ChartTitle Text="Product sales for 2011">

</ChartTitle>

<Legend>

<Appearance Position="Bottom" />

</Legend>

</telerik:RadHtmlChart>

C#:

protected void Page_Load(object sender, EventArgs e)

{

RadHtmlChart1.DataSource = GetData();

RadHtmlChart1.DataBind();

}

protected DataTable GetData()

{

DataTable dt = new DataTable();

dt.Columns.Add("ID", typeof(int));

dt.Columns.Add("Volume", typeof(int));

dt.Columns.Add("DATA_TIME", typeof(DateTime));

dt.Rows.Add(1, 2, new DateTime(2011, 06, 12));

dt.Rows.Add(2, 5, new DateTime(2011, 12, 12));

dt.Rows.Add(3, 6, new DateTime(2012, 06, 17));

dt.Rows.Add(4, 4, new DateTime(2012, 09, 18));

dt.Rows.Add(5, 7, new DateTime(2013, 03, 18));

return dt;

}
