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:

Any idees?

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>
 
 <telerik1:RadCartesianChart.Series>
  <telerik1:LineSeries
   CategoryBinding="XVal"
   ItemsSource="{Binding series1}"
   Stroke="RoyalBlue"
   StrokeThickness="1"
   ValueBinding="YVal">
   
  </telerik1:LineSeries>
   <telerik1:LineSeries
   CategoryBinding="XVal"
   ItemsSource="{Binding series2}"
   Stroke="Purple"

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>

Hi,
