    Hello Telerik,

    I initially posted this in the Reporint forum because I am using the chart in a Telerik Report, but I haven't recevied a response.  Seems like maybe this is a more appropiate place... 

    I am creating a chart from a SQL datasource.  I have two series that are bound to columns on the datasource.  If I preview the chart, it looks good and the chart matches the data.  My next step is to display my own custom X-Axis labels.  I do this by setting PlotArea.XAxis.AutoScale = false and create the items manually.  However when I do this and preview the chart, the chart does not look correct (the line does not match the data from the database).

    This forum post seems to be related:
    It suggests that I do not set the xvalue inside my chart series.  However, I am adding the series by binding to a datasource, so I do not see how to make this work in my case.

    //set the datasource 
    chart1.DataSource = this.sqlDataSource1; 
    //add new xaxis series items 
    chart1.PlotArea.XAxis.AutoScale = false
    chart1.PlotArea.XAxis.AddRange(1, 7, 1); 
    chart1.PlotArea.XAxis[0].TextBlock.Text = "12/1/10"
    chart1.PlotArea.XAxis[1].TextBlock.Text = "12/5/10"
    chart1.PlotArea.XAxis[2].TextBlock.Text = "12/10/10"
    chart1.PlotArea.XAxis[3].TextBlock.Text = "12/15/10"
    chart1.PlotArea.XAxis[4].TextBlock.Text = "12/20/10"
    chart1.PlotArea.XAxis[5].TextBlock.Text = "12/25/10"
    chart1.PlotArea.XAxis[6].TextBlock.Text = "12/30/10"
    //add the series 1 
    ChartSeries seriesAvg = new ChartSeries(); 
    seriesAvg.DataYColumn = "Average"
    seriesAvg.Type = ChartSeriesType.Area; 
    seriesAvg.DefaultLabelValue = ""
    //add the series 2 
    ChartSeries seriesMax = new ChartSeries(); 
    seriesMax.DataYColumn = "Max"
    seriesMax.Type = ChartSeriesType.Line; 
    seriesMax.DefaultLabelValue = ""

    Am I doing this totally wrong, or is there a work around?

    Thanks, Chris

    Hello Chris Ward,

    I created a sample project with the given guidelines. You can find it in the attached file. However I was not able to reproduce this case. Can you please provide some additional information about it? I will appreciate if you send us an entire sample project. Thus we will provide more straight-to-the-point solution.
