Axis.IsZeroBased bug

[Aleksey Zdanovich]

Hi,

I create a simple chart in xaml.

<Controls:RadChart x:Name="chartControl"  >

                    <Controls:RadChart.SamplingSettings>

                        <telerik:SamplingSettings SamplingThreshold="999" />

                    </Controls:RadChart.SamplingSettings>
</Controls:RadChart>

then configure Axis

chartControl.DefaultView.ChartArea.AxisX.AutoRange = true;
chartControl.DefaultView.ChartArea.AxisX.Title = title;
chartControl.DefaultView.ChartArea.AxisX.IsZeroBased = true;

Version 2010.3.1119.1040, all ok.

Version 2010.3.1326.1040, an exception is thrown on  the line

chartControl.DefaultView.ChartArea.AxisX.IsZeroBased = true;

Callstack:

   ? System.Convert.ToInt64(Double value)
   ? Telerik.Windows.Controls.Charting.AxisX.InitializeAxisValuesForAutoRange()
   ? Telerik.Windows.Controls.Charting.Axis.IsZeroBasedPropertyChanged(DependencyObject target, DependencyPropertyChangedEventArgs args)
   ? Telerik.Windows.PropertyMetadata.<>c__DisplayClass1.<Create>b__0(DependencyObject d, DependencyPropertyChangedEventArgs e)
   ? System.Windows.DependencyObject.RaisePropertyChangeNotifications(DependencyProperty dp, Object oldValue, Object newValue)
   ? System.Windows.DependencyObject.UpdateEffectiveValue(DependencyProperty property, EffectiveValueEntry oldEntry, EffectiveValueEntry& newEntry, ValueOperation operation)
   ? System.Windows.DependencyObject.SetValueInternal(DependencyProperty dp, Object value, Boolean allowReadOnlySet)
   ? System.Windows.DependencyObject.SetValue(DependencyProperty dp, Object value)<br>
   ? Telerik.Windows.Controls.Charting.Axis.set_IsZeroBased(Boolean value)

What's wrong? To all appearances, double is NaN...

SL 4, IE 8, Telerik 2010.3.1326.1040

Hi Aleksey Zdanovich,

Our developers are already on the task and fix for this issue will be available with one of the upcoming LIB releases.
