Hide negative values line

[Gregory Greg]

How do I hide the negative values line (the y-axis zero) introduced with the Q3.2009 version?

Thanks
Greg

Hello Gregory Greg,

You can achieve the desired effect by modifying the respective PlotArea axis style like this:

XAML

<UserControl x:Class="SilverlightApplication1.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:controls="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls"
    xmlns:control="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Charting"
    xmlns:chart="clr-namespace:Telerik.Windows.Controls.Charting;assembly=Telerik.Windows.Controls.Charting"
    xmlns:mscorlib="clr-namespace:System;assembly=mscorlib"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

    <Grid x:Name="LayoutRoot">
        <Grid.Resources>
            <Style x:Name="CustomPlotAreaAxisXStyle" TargetType="chart:AxisX2D">
                <Setter Property="AxisLineStyle">
                    <Setter.Value>
                        <Style TargetType="Line">
                            <Setter Property="Visibility" Value="Collapsed" />
                        </Style>
                    </Setter.Value>
                </Setter>
            </Style>
        </Grid.Resources>

        <control:RadChart x:Name="RadChart1" />

    </Grid>

</UserControl>

C#

RadChart1.DefaultView.ChartArea.PlotAreaAxisXStyle = this.CustomPlotAreaAxisXStyle;
RadChart1.ItemsSource = new int[] { 10, 20, -20, -30, 20 };

Hope this helps.
