    I have a chart that is displaying 365 days of data and I want the X axis labeled only by month. Seems like a simple request but after spending considerable time looking at documentation and numerous forum posts, it looks like it is not as easy as it seems. I have also included an image of how my chart renders. I can get the range on the x axis to display fine however the plotted line does not extend to the end of the graph. Even if the monthly labels are impossible to achieve, I need to AT LEAST get that plotted line to scale to the end of the graph. Of course when I turn the auto scaling on the X axis range does not work.

    Here is my chart and code behind.

    <telerik:RadChart ID="rc1" runat="server" DataSourceID="SqlDataSource1" DefaultType="Line"
            <telerik:ChartSeries DataYColumn="ClosePrice" Name="ClosePrice" Type="Line">
                <Appearance ShowLabels="false">
                    <FillStyle MainColor="213, 247, 255">
        <Legend Visible="False">
            <Appearance Visible="False">
        <PlotArea XAxis-AutoScale="False">
            <Appearance Dimensions-Margins="18%, 5%, 22%, 10%">
            <XAxis LayoutMode="Inside" AutoScale="false" LabelStep="45">
                <Appearance ValueFormat="ShortDate" MajorGridLines-Visible="false">
                    <LabelAppearance RotationAngle="45" Position-AlignedPosition="Top">
            <YAxis IsZeroBased="false" AxisMode="Extended">
            <TextBlock Text="Title Here" />

    SqlDataSource1.SelectCommand = "select * from BofIHistoricalData where datadate between '" + 
                DateTime.Now.Date.AddMonths(-12).ToString() + "' and '" + DateTime.Now.Date.AddDays(-1) + "'" +
                "order by datadate";
                double today = DateTime.Now.Date.ToOADate();
                double lastYear = DateTime.Now.Date.AddMonths(-12).ToOADate();
                rc1.PlotArea.XAxis.AddRange(lastYear, today, 1);

    Hello Tony,

    Check the following forum thread which discusses similar scenario.
    Display custom format in x-axis.

    I have went through both of those forum posts. I need the X-axis labels to change dynamically based on the dates within  the range of data. They can not be static. 

    The code that I included does work some what however the plotted line stops before the end of the graph. Most urgently I need to address that issue.


    As an update I think I found partially what the issue is. The yearly data I was populating only had weekdays and did not have data points for Saturdays and Sundays but the range on the X-axis was set for the entire year. That is why the plotted line did not reach the end of the range.
