Chart stack overflow

Hello folks,

I recently bought wpf elements, during the evaluation, I didn't have any major issues. Now, I've downloaded the latest release (6.0.2165.22593) and am using it instead of the evaluation which was slightly older.

The new version crashes with a stack overflow whenever I use the zoom rectangle and there's data in my scatter plot. If I disable the zoom and use the scrollbars, it'll crash in the same manner (with a stack overflow).

The itemssource is a list of DateTimeDoubleViewModel which inherits from mindscapes DateTimeDouble. the only difference is that there is an added TooltipText property:

public String TooltipText
{
  get
  {
    return DateTime.ToShortDateString() + " " + DateTime.ToShortTimeString() +"\n" + Double.ToString("F1") + "mm";
  }
}

The following is the xaml code I use to generate the plot:

<ms:Chart Name="Chart" LegendPosition="None" Title="{Binding HeaderText}" Margin="10" ZoomMode="Both" Grid.Column="0">
        <ms:ScatterSeries ItemsSource="{Binding Elements}" SeriesBrush="{Binding Palette[0]}" SymbolStyle="{StaticResource CircleChartSymbolStyle}"
                     Title="{x:Static p:Resources.Snow_Height}" ToolTipBinding= "{Binding TooltipText}" />       
        <ms:Chart.BackgroundElements>
          <ms:ChartGrid MinorHorizontalGridLineBrush="#AAAAAA" MinorHorizontalDashArray="2,2">
            <ms:ChartGrid.HorizontalStripeBrushes>
              <SolidColorBrush Color="Transparent" />
              <SolidColorBrush Color="#EFEFEF" />
            </ms:ChartGrid.HorizontalStripeBrushes>
          </ms:ChartGrid>
        </ms:Chart.BackgroundElements>
        <ms:Chart.XAxis>
          <ms:ChartAxis Title="Date" ValueConverter="{StaticResource DateTimeScale}"  LabelFormat="{}{0}"
                      TickMarkMode="Movable" MinorTickMarkVisibility="Visible" IsSliderVisible="True"
                      MinimumRange="20" 
                      LabelRotation="35" LabelStep="1" Style="{StaticResource AxisStyle}"/>

        </ms:Chart.XAxis>
        <ms:Chart.YAxis>
          <ms:ChartAxis Title="{Binding SnowHeight}" TickMarkMode="Movable" Minimum="-1" MinorTickMarkVisibility="Visible"
                      LabelFormat="{}{0:0mm}" Style="{StaticResource AxisStyle}" IsSliderVisible="True"/>
        </ms:Chart.YAxis>
      </ms:Chart>

How do I go about debugging the situation?

Digging a bit deeper I found that my stack overflow doesn't occur when i remove the MinimumRange property from the ChartAxis:

    <ms:Chart.XAxis>
      <ms:ChartAxis Title="Date" ValueConverter="{StaticResource DateTimeScale}"  LabelFormat="{}{0}"
                  TickMarkMode="Movable" MinorTickMarkVisibility="Visible" IsSliderVisible="True"
                  MinimumRange="20" 
                  LabelRotation="35" LabelStep="1" Style="{StaticResource AxisStyle}"/>

    </ms:Chart.XAxis>

turns into

    <ms:Chart.XAxis>
      <ms:ChartAxis Title="Date" ValueConverter="{StaticResource DateTimeScale}"  LabelFormat="{}{0}"
                  TickMarkMode="Movable" MinorTickMarkVisibility="Visible" IsSliderVisible="True"
                  LabelRotation="35" LabelStep="1" Style="{StaticResource AxisStyle}"/>

    </ms:Chart.XAxis>

but now I have a new issue, if I add the ValueConverter, then when I zoom in, the x axis doesn't zoom correctly and it doesn't actually zoom on the square selection.

Hello

All your code looks fine, and I have not been able to reproduce either of your issues at our end. Could you please send a list of the data you are plotting (datetime - double pairs).

I downloaded the nightly and the bugs no longer occur.

Ah, excellent, great to hear it is solved now.
