I seem to have a problem with a multiple-series bar chart.  I have a custom X-Axis, which works fine.   The Y-Axis is simply a number of phone calls figure, so the auto-scale axis would be fine.  However, the values do not seem to marry up with those in the bar series.  The image below illustrates this (flickr link, not sure if you can embed pics on here) :

As you can see, the rightmost green bar = 111, which seems to line up with the Y-axis - however, none of the others do. 

The XAML for the chart is as follows (incomplete, the remainder is legend name, title etc):
<control:RadChart x:Name="skillBarChart"   
                telerik:Theming.Theme="Office_Black"  > 
                         <chart:ChartDefaultView > 
                            <chart:ChartDefaultView.ChartArea > 
                                <chart:ChartArea    x:Name="BarChartArea"  
                                                    FontFamily="Arial" FontSize="18"  
                                                    Height="446.848" Width="985"
                                        <chart:AxisX    MajorGridLinesVisibility="Collapsed" 
                                                        Title="Skill" /> 
                                        <chart:AxisY    MajorGridLinesVisibility="Collapsed" 
                                                        Title="Calls" AutoScale="True"  
                                                        MinValue="0" MaxValue="500"/> 
                                        <LinearGradientBrush    EndPoint="0.5,1" StartPoint="0.5,0"
                                                <GradientStop           Color="#FF000000" Offset="0"/> 
                                                <GradientStop           Color="#FF63B2DE" Offset="1"/> 

I'm populating the chart as follows (again a snippet) :

                            foreach (string s in skillname) 
                                DataPoint Idp = new DataPoint(); 
                                Idp.YValue = noOfInCalls[Array.IndexOf(skillname, s)]; 
                                Idp.XValue = Array.IndexOf(skillname, s); 
                                DataPoint Odp = new DataPoint(); 
                                Odp.YValue = noOfOutCalls[Array.IndexOf(skillname, s)]; 
                                Odp.XValue = Array.IndexOf(skillname, s); 

I then reformat the X-Axis with specific values for the 'skillname' to which each Y value corresponds, but do not do anything with the Y-Axis.   However,  I still get the issue as shown in the image.  The '120' marker in the image is also cut off by the chart title area which I cannot seem to resolve.

Any assistance gratefully received!  Thanks!

Hello Brian,

This is my reply to your support ticket on the same matter:

It seems you have hit a bug in RadChart - the Y axis ticks are not positioned correctly when a custom defaultview is provided. While our developers investigate the issue, you can use the approach shown in the attached example -- configure the default Axis in code.

Please accept our apologies for the inconvenience caused by this problem.
Your Telerik points have been updated.

Kind regards,
the Telerik team
