Data unavailability in one series

[Avinash]

Hi,

Currently I am adding two series on one chart. As per functionality, I am always showing 6 bars(last 6 months) on it. So there will be always 2 bars for one month becuase of 2 series.

Now due to some reason if there is no data in series 1 and data available for series 2. However, I am not able to show data on first bar even if I have series 2 data.
e.g: If I dont have data for month of december for series 1 and have series 2 data. Graph is not showing december's bar.

So please help me out to resolve this issue or let me know any other workarround.

Thanks,
Avinash

Hello Avinash,

We were unable to reproduce the problematic behavior in our local tests. Please review the attached code snippet and let us know how to reproduce the erroneous issue:

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        ChartSeries series = new ChartSeries();

        series.Items.Add(new ChartSeriesItem(DateTime.Today.AddMonths(-4).ToOADate(), 50));
        series.Items.Add(new ChartSeriesItem(DateTime.Today.AddMonths(-3).ToOADate(), 40));
        series.Items.Add(new ChartSeriesItem(DateTime.Today.AddMonths(-2).ToOADate(), 60));
        series.Items.Add(new ChartSeriesItem(DateTime.Today.AddMonths(-1).ToOADate(), 90));
        series.Items.Add(new ChartSeriesItem(DateTime.Today.ToOADate(), 10));

        RadChart1.Series.Add(series);

        ChartSeries series2 = new ChartSeries();
        series2.Items.Add(new ChartSeriesItem(DateTime.Today.AddMonths(-5).ToOADate(), 10));
        series2.Items.Add(new ChartSeriesItem(DateTime.Today.AddMonths(-4).ToOADate(), 20));
        series2.Items.Add(new ChartSeriesItem(DateTime.Today.AddMonths(-3).ToOADate(), 30));
        series2.Items.Add(new ChartSeriesItem(DateTime.Today.AddMonths(-2).ToOADate(), 40));
        series2.Items.Add(new ChartSeriesItem(DateTime.Today.AddMonths(-1).ToOADate(), 50));
        series2.Items.Add(new ChartSeriesItem(DateTime.Today.ToOADate(), 60));

        RadChart1.Series.Add(series2);


        RadChart1.PlotArea.XAxis.IsZeroBased = false;
        RadChart1.PlotArea.XAxis.AddRange(DateTime.Today.AddMonths(-5).ToOADate(), DateTime.Today.ToOADate(), 30);
        RadChart1.PlotArea.XAxis.Appearance.ValueFormat = Telerik.Charting.Styles.ChartValueFormat.ShortDate;
        RadChart1.PlotArea.XAxis.Appearance.LabelAppearance.RotationAngle = 320;
        RadChart1.AutoLayout = true;
    }
}

All the best,
