Newly release Internal Build, 821, does not display AxisX.Title and AxisY.Title

[Patrick Fletcher]

Hi Folks,

When I assigned values to AxisX.Title and AxisY.Title, these values do not get displayed when I run the program.   Here is a sample of my XAML code, GDF and OPTIME does not get displayed:

<

 

telerik:RadChart Width="299" Height="299" ItemsSource="{Binding Path=ConditionIndicatorDataPoints}">

 

 

 

 

    <telerik:RadChart.DefaultView>

 

 

 

 

            <telerik:ChartDefaultView>

 

 

 

 

                    <telerik:ChartDefaultView.ChartTitle>

 

 

 

 

                            <telerik:ChartTitle Content="{Binding Path=ChartName}" />

 

 

 

 

                    </telerik:ChartDefaultView.ChartTitle>

 

 

 

 

                    <telerik:ChartDefaultView.ChartLegend>

 

 

 

 

                            <telerik:ChartLegend Header="GDF"/>

 

 

 

 

                    </telerik:ChartDefaultView.ChartLegend>

 

 

 

 

                    <telerik:ChartDefaultView.ChartArea>

 

 

 

 

                            <telerik:ChartArea PlotAreaStyle="{StaticResource customStyle}">

 

 

 

 

                                    <telerik:ChartArea.AxisY>

 

 

 

 

                                            <telerik:AxisY Title="GDF" Visibility="Visible" AxisStyles="{DynamicResource customAxisTitleStyle}" />

 

 

 

 

                                    </telerik:ChartArea.AxisY>

 

 

 

 

                                    <telerik:ChartArea.AxisX>

 

 

 

 

                                            <telerik:AxisX Title="OPTIME"  Visibility="Visible" AxisStyles="{DynamicResource customAxisTitleStyle}" />

 

 

 

 

                                    </telerik:ChartArea.AxisX>

 

 

 

 

                          </telerik:ChartArea>

 

 

 

 

                    </telerik:ChartDefaultView.ChartArea>

 

 

 

 

            </telerik:ChartDefaultView>

Hi Patrick,

I just created an example, based you your xaml and the chart seems to work fine for me. You can find this example attached. Give it a try and let me know if you can see the axis titles.

I have removed the axis styles like this one: AxisStyles="{DynamicResource customAxisTitleStyle}"  and it seems this might be the reason for showing the titles in my example. Please, check all the styles you use and verify that the axis titles are not hidden in them.

Ok, I don't think I did make it clear the first time, I am sorry about that.  When I assigned values to AxisX.Title and AxisY.Title using XAML, these values do not get displayed when I run the program.  Furthermore, here at Sikorsky, we are using the MVVM pattern, this mean for our UIs we are sticking with XAML and avoiding code-behind.  The vb sample that you sent me did not address my problem for two simple fact:

    1.    It is not in XAML, but instead using code-behind.

    2.    the problem is with AxisX.Title and AxisY.Title, the bug is not with XCategory.  You avoid using AxisX.Title and 
           AxisY.Title in your sample, while at the same time using XCategory that does not interest Sikorsky.

Sikorsky would like to title the x-axis and the y-axis of our charts using XAML, and this feature of Telerik RadChart is not working since the release of internal build 821.  Here is a sample of the XAML code again, and again GDF and OPTIME is not displayed when the code execute, I would like to see them displayed using XAML:

<

 

telerik:RadChart x:Name="radChartTemplate" Width="299" Height="299">

 

 

 

<telerik:RadChart.DefaultView>

 

 

 

<telerik:ChartDefaultView>

 

 

 

<telerik:ChartDefaultView.ChartTitle>

 

 

 

<telerik:ChartTitle Content="{Binding Path=ChartName, Mode=OneWay}" />

 

 

 

</telerik:ChartDefaultView.ChartTitle>

 

 

 

<telerik:ChartDefaultView.ChartLegend>

 

 

 

<telerik:ChartLegend Header="Mechanical"/>

 

 

 

</telerik:ChartDefaultView.ChartLegend>

 

 

 

<telerik:ChartDefaultView.ChartArea>

Hi Patrick,

I am sorry, it seems I have attached the wrong example. I have now attached the correct one, it uses code-behind only to compose the datasource, hope it's not a problem as it does not seem to be related to the issue itself. Once again - please, check the axis styles you use and let us know how it goes.

Hi guys,

The chartaxes.zip sample that you sent me helps, it worked.  I ignore to tell you that I was using Telerik chart in a ItemsControl, in my case a ListBox.  When I take the chart XAML in your sample and places it in a ListBox, all the text in the chart turns black, including the axises titles.  With a black background and black foreground the text in the chart appears to disappear.  However, I was able to get around this by setting the ListBox Foreground property to white.  Thanks again for your help!

Ok guys, we have a problem.  When I hard code the value for AxisX.Title and the AxisY.Title in XAML things work, the axis titles are shown.  But when I bind to AxisX.Title and AxisY.Title, things does not work, the axis titles do not show when the program runs.  Here is the XAML I am using:

<

 

ListBox Foreground="White">

 

 

 

<ListBoxItem>

 

 

 

<telerik:RadChart x:Name="RadChart1" Width="299" Height="299">

Hi Patrick,

I am afraid you will not be able to databind AxisX.Title and AxisY.Title as AxisX and AxisY are not dependency objects, so binding is not available.Please, accept our apologies for the inconvenience caused.

How soon can Telerik make AxisX.Title and AxisY.Title dependency objects/properties so we can databind to these properties?

[Ves]

Hi Patrick,

I am afraid this change is not currently in our plans. I will make sure it is discussed on the next meeting dedicated to chart features, but I am not able to provide you with a certain time frame for the moment. Once again, I apologize for the inconvenience caused.

Kind regards,
Ves

Perhaps if I explain to you what I am trying to do then you will see the need for making AxisX.Title and AxisY.Title dependency objects/properties.  What I am doing is styling a ItemsControl, in  this case a ListBox, with a style that has a Telerik chart.  My goal is to be able to add multiple charts, to the ListBox, with different AxisX.Title and AxisY.Title for each charts showing different data.  Therefore, it is not enough to databind the YValue to a varying collection of datapoints, but I also I need to vary AxisX.Ttile and AxisY.Title using databinding.  In one of my chart for example, AxisY.Title will have a value RMS, while AxisX.Title for this chart will have a value of OPTIME. Hence, AxisY.Title=RMS and AxisX.Title=OPTIME.  Another chart in my ListBox will have AxisY.Title=SM1 and AxisX.Title=OPTIME, ...etc.  Currently all of these charts are simultaneously being displayed in the ListBox with  no problem, except the problem with not being able to databind the AxisX.Title and AxisY.Title.   I could make AxisX.Title and AxisY.Title dependency objects/properties myself, but for that I would need the source code.  Here is the Style that I am applying to the ListBox:

<

 

Style x:Key="conditionIndicatorItemControlTemplate" TargetType="{x:Type ListBox}">

 

 

 

<Setter Property="IsSynchronizedWithCurrentItem" Value="True" />

 

 

 

<Setter Property="Foreground" Value="White" />

Hello Patrick,

I must apologize, actually AxisX and AxisY are dependency objects, so the only change would be to make Title property a dependency property. I have discussed this with our development team and they assured me this will be done for the next official release.

When will the next official release be?

Hello Patrick,

The release of RadControls for WPF Q3 2009 is planned for the first half of November. I hope this time frame will allow you to integrate the new version in your project.
