Hi telerik,

I have to create chart with code not xaml having LogarithmicAxis and LinearAxis, but can't display series successfully
and don't know what is my mistake, though I refered your sample code in this forum and your doc as well.
My code snippet is as follows;

private RadCartesianChart GetChart()

{

RadCartesianChart cartChart = new RadCartesianChart();

cartChart.HorizontalAxis = new LinearAxis() { Maximum = 50, Minimum = 17, MajorStep = 3 };

cartChart.VerticalAxis = new LogarithmicAxis() { LogarithmBase = 10, Minimum = 1000, Maximum = 1000000 };

LineSeries lineSeries = new LineSeries() { ShowLabels = true };

// lineSeries.CategoryBinding = new PropertyNameDataPointBinding() { PropertyName = "Age" };

lineSeries.CategoryBinding = new GenericDataPointBinding<CordXy, double>() { ValueSelector = value => value.Age };

lineSeries.ValueBinding = new GenericDataPointBinding<CordXy, double>() { ValueSelector = cord => cord.Num };

// lineSeries.ValueBinding = new PropertyNameDataPointBinding() { PropertyName = "Num" };

lineSeries.ItemsSource = CordXy.GetFollicleList();

cartChart.Series.Add(lineSeries);

DoubleCollection aray = new DoubleCollection(new double[] {1,1});

cartChart.Annotations.Add(

new CartesianCustomLineAnnotation

{

HorizontalFrom = 35,

HorizontalTo = 35,

VerticalFrom = 0,

VerticalTo = 1000000,

Stroke = new SolidColorBrush(Colors.Blue),

StrokeThickness = 2,

DashArray = aray

});

return cartChart;

}

public class CordXy

{

public double Age { get; set; }

public double Num { get; set; }

public static ObservableCollection<CordXy> GetFollicleList()

{

var result = new ObservableCollection<CordXy>();

for (int i = 0; i < 33; i++)

{

var add = new CordXy();

add.Age = i + 18;

add.Num = Math.Pow(10, (5.717 - 0.00019 * Math.Pow(add.Age, 2.452)));

result.Add(add);

}

return result;

}

As you see, x-axis is linear which shows age of person and y-axis shows calculated value as logarithmic.
I think I did correct as you told with your sample and doc, but no luck.
Pls see my attached image and advise me what I made a mistake.

Thank you in advance.

Setting Plot Band Annotations from code behind

Is there a way to set plot band annotations dynamically from C# code behind instead of from XAML?

The examples demonstrate the XAML approach, for instance,
<telerik:CartesianPlotBandAnnotation Axis="{Binding ElementName=chart3HAxis}" To="3/2/2014" From="3/4/2014" />

but how to accomplish the sample thing using code behind, dynamically.

Error "cannot locate resource 'themes/genericwindows8touch'".

Yesterday I created a new WPF app using the Telerik WPF C# project template. I chose the Windows 8 theme from the control panel, and all seems fine. My app even runs and looks like Windows 8, but when I try and instantiate a UserControl in another project, that contains a RagGridView, on my InitializeComponent call, I get a MissingManifestResourceException. This explains that:

"Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "Telerik.Windows.Controls.GridView.g.resources" was correctly embedded or linked into assembly "Telerik.Windows.Controls.GridView" at compile time, or that all the satellite assemblies required are loadable and fully signed."

I also get a warning in my XAML editor, "cannot locate resource 'themes/genericwindows8touch'", and the all the XAML is underlined with blue, squiggly lines.

I never had this problem when I created a Telerik C# WPF project without choosing a theme. What is wrong?

Binding data of a column to an indexer element

If I use the following binding in a GridViewDataColumn

Column.Binding = new System.Windows.Data.Binding("rowdata[INDEX]");

I can see the data in the table just fine, but when i try to filter/group it doesn't work (when i click on the filter button all i see is [null]).

I can't create the columns in the XAML file due to creating the grid dynamically in the code behind.

The gridview.dll version I use is 2011.3.1220.40, i'd rather not update to a newer version if possible.

Thanks in advance!
