Data outside of maximum vertical axis plots to top-left corner

[David]

Hi,

I've found that plotting data with where the Y value is above the maximum vertical axis plots somewhere to the top-left corner of component (outside of the visible component). Here's an example:

XAML:

<Window
    x:Class="RadChartViewSimpleTest"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:chart="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Chart"
    xmlns:chartView="clr-namespace:Telerik.Windows.Controls.ChartView;assembly=Telerik.Windows.Controls.Chart"
    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
    Width="300"
    Height="300">
    <Grid>
        <Grid.ColumnDefinitions>
            <ColumnDefinition />
            <ColumnDefinition />
        </Grid.ColumnDefinitions>
        <DataGrid
            ItemsSource="{Binding}" />
        <chart:RadCartesianChart
            Grid.Column="1">
            <chart:RadCartesianChart.HorizontalAxis>
                <chartView:LinearAxis />
            </chart:RadCartesianChart.HorizontalAxis>
            <chart:RadCartesianChart.VerticalAxis>
                <chartView:LinearAxis
                    Maximum="100" />
            </chart:RadCartesianChart.VerticalAxis>
            <chart:RadCartesianChart.Series>
                <chartView:ScatterLineSeries
                    x:Name="ScatterLineSeries1"
                    ItemsSource="{Binding}" />
            </chart:RadCartesianChart.Series>
        </chart:RadCartesianChart>
    </Grid>
</Window>

VB:

Imports Telerik.Windows.Controls
Imports Telerik.Windows.Controls.ChartView

Public Class RadChartViewSimpleTest

    Public Sub New()
        InitializeComponent()

        Dim Points As New List(Of Point)
        For i As Integer = 0 To 150 Step 5
            Points.Add(New Point(i, i))
        Next
        For i As Integer = 0 To 150 Step 5
            Points.Add(New Point(155 + i, i))
        Next
        Me.DataContext = Points

        Dim genericBinding As New GenericDataPointBinding(Of Point, Double)
        genericBinding.ValueSelector = Function(t As Point) t.X
        ScatterLineSeries1.XValueBinding = genericBinding
        genericBinding = New GenericDataPointBinding(Of Point, Double)
        genericBinding.ValueSelector = Function(t As Point) t.Y
        ScatterLineSeries1.YValueBinding = genericBinding
    End Sub
End Class

The chart has a maximum vertical (linear) axis of 100, however the data generated in code-behind plots from 0 to 150. The resulting graph ends up quite funky (and incorrect).

I've also noted that irrespective of what I set for "RangeExtendDirection" in the vertical linear axis, the maximum range is never extended and the minimum range is always extended, ie. RangeExtendDirection is always acts as Negative irrespective of the value I set it to.

Kind regards,
Dave.

ps. Love the new performance of the ChartView component!

Hello Dave,

We are aware of this issue and our developers have already fixed it. Please, download and try our latest LIB, which should solve this problem.

Hi Nikolay,

I'm happy to report that the latest LIB (2011.3.1316.40) fixes the issue described, however I've now got a new problem that opening any XAML file in any project that contains a Telerik control in design view generates the following error in the XAML designer:

System.IO.FileLoadException

Is this an issue with this build? While I understand LIB are exactly that - internal builds that aren't production ready, what can I do to fix the original problem in this thread? Will there be a newer build that restores the XAML designer or what I can I do to resolve the issue with the 2011 Q3 SP1 release?

Kind regards,
Dave.

Hi Dave,

We haven't been able to reproduce this error in our local tests. Please, find attached a sample application based on the code you've sent us that uses the same version of the LIB 2011.3.1316.40. It works as expected on our side, so perhaps we are missing some of the details of your scenario. It would be very helpful for us if you're able to give it a try and in case the issue persists modify it and send it back to us. You may also try the latest LIB, which version 2011.3.1323.40.

As for the fix, it will be included in the next official version, which would be our 2012 Q1 release, scheduled for mid february.

Regards,
Nikolay

Hi Nikolay,

I updated to the latest LIB (2011.3.1323.40) which fixes the original issue and no longer generates an error in the XAML designer, so I'm happy to continue to use this LIB to resolve the original issue. I'm not sure what caused the error in the XAML designer (it even occurred in the sample code I posted above), but since this is now resolved in the latest LIB and these are fully supported releases, I'm happy with this outcome.

Many thanks to the developers and your support team for helping me with the original issue.

Kind regards,
Dave.
