Chart series data not displaying correctly when .AutoScale = false

[Chris Ward]

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: http://www.telerik.com/community/forums/aspnet/chart/trouble-with-custom-xaxis-labels.aspx
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;
//COMMENT OUT THIS SECTION AND THE CHART LOOKS GOOD
//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 = "";
chart1.Series.Add(seriesAvg);
//add the series 2
ChartSeries seriesMax = new ChartSeries();
seriesMax.DataYColumn = "Max";
seriesMax.Type = ChartSeriesType.Line;
seriesMax.DefaultLabelValue = "";
chart1.Series.Add(seriesMax);

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.
