Hi, is it possible to integrate the pivot with a pie chart?

 

Something like this but with a pie

Thank you

Hi Guys,

I've got a very simple example I have been trying to get to work, specifically, I am binding a RadCartesianChart with a stacked barseries. However unfortunately I have been unable to get the RadLegend control to work with my example.

So my model looks like this.

 

and my chart xaml looks like this

 

and my radlegend looks like this.

 

 

Basically what I want to achieve is the ability to display the StackGroup items in the radlegend.

However no matter what I do Chart.LegendItems seems to contain zero elements and I consequently can't get it to display my stacked groups in the legend. 

Can anyone provide any guidance on what I might be doing wrong?

 

 

 

I need a line chart where the user can click and drag a data point up and down. When the user releases the data point I will need to calculate various values. Is this possible with your controls and if so is there a demo available?

Have minor ticks and grid lines gone away forever, or is it possible to add them to a RadCartesianChart?

 

Thanks!

Brad.

I have an sporadically unexplicable OverflowException in RibbonView. 

All information i have from the user is, they are scrolling or using the mousewheel inside the window 
and a  small Stack Trace

Exception:

I'm trying to create a LineSeries chart with two series of data which are displayed on top of each other. The display data is data bound to series1 and series2. When I use the code below the two graphs are adjacent to each other (series1 on the left and series2 on the right). How can I get the two series to display on top of each other?

<telerik1:RadCartesianChart x:Name="RadChart1">
 <telerik1:RadCartesianChart.HorizontalAxis>
  <telerik1:CategoricalAxis
   x:Name="AxisX"
   Title="Length (km)"
   IsStepRecalculationOnZoomEnabled="True"
   LabelFormat="{}{0:0.000}"
   MajorTickInterval="1000"
   PlotMode="OnTicks"
   SmartLabelsMode="SmartStep"
   TitleTemplate="{DynamicResource BoldAxisTitle}" />
 </telerik1:RadCartesianChart.HorizontalAxis>
 
 <telerik1:RadCartesianChart.VerticalAxis>
  <telerik1:LinearAxis
   x:Name="AxisY"
   Title="dB"
   MajorStep="5"
   Maximum="40"
   Minimum="0"
   TitleTemplate="{DynamicResource BoldAxisTitle}" />
 </telerik1:RadCartesianChart.VerticalAxis>

Hello,
I have searched the forum but have not found a way to get notification when:
1.  a column is moved 
2.  a column is resized

What is the straightforward way to capture these events? I'm trying to do this from a custom control that extends RadGridView.

I'm using Q2 release.

Thanks,
Laura

Hi Team,

I would like to set few styles, namely TextDecorations like StrikeThrough, Underline and other styles like Horizontal Alignment, Boldness and Font Style programmatically by creating a FrameworkElementFactory of type Textblock and then assigning the same to a DataTemplate of type GridViewRow, which is then assigned to the ContentTemplateProperty of the GridViewRow; but to no avail.

Could you please guide me on the same.

Please let me know if any details/clarifications are required.

Thanks,

Swapnil Ramteke

Hello

I used the following code to export to image

        Dim filename As String = "C:\Export\ExportedChart.png"

        Using fileStream As Stream = File.Open(filename, FileMode.OpenOrCreate)
            Telerik.Windows.Media.Imaging.ExportExtensions.ExportToImage(Me.chart, fileStream, New PngBitmapEncoder())
        End Using

 

But the exported image misses the X and Y coordinate values. How can I export the image exactly as seen in the UI

I would like to export to PDF as well.

How can I display the X and Y values in the tool tip for radCartesianchart bar series

 

In radChart, there is a option as below:

<telerik:BarSeriesDefinition ItemToolTipFormat="the X value is #X, the Y value is #Y"ShowItemToolTips="True" />
    </telerik:SeriesMapping.SeriesDefinition>
