title: WPF Metro UI Charts - Negative Values
body: <p>I am trying to use the Library <strong>WPF Metro UI Charts</strong>, which is derivated from <strong>Modern UI Charts</strong>. However i'm having trouble with <strong><em>ClusteredColumnChart</em></strong> when i try to use use charts inside a <em>Page</em> instead of a <em>Window</em>. The graph always show negative axis in Y, even when there is no negative value. When i use the class <strong><em>Window</em></strong> it works properlly. 
  The graph generated looks like this: </p>

  <p>My XAML is this:</p>
  
  <pre><code>&lt;GAChart:ClusteredColumnChart Style="{StaticResource MinimalChartStyle}"
                  ChartTitle="{Binding Titulo}"
                  ChartSubTitle="{Binding SubTitulo}"
                  SelectedItem="{Binding selectedItem, Mode=TwoWay}"
                                            Width="400" Height="400"
                                            &gt;
      &lt;GAChart:ClusteredColumnChart.Series&gt;
          &lt;GAChart:ChartSeries
                          SeriesTitle="{Binding Dados.seriesDisplayName}"
                          DisplayMember="date"
                          ItemsSource="{Binding Dados.Items}" 
                          ValueMember="amount" /&gt;
      &lt;/GAChart:ClusteredColumnChart.Series&gt;
  &lt;/GAChart:ClusteredColumnChart&gt;
  </code></pre>
  
  <p>The codebehind is exactly the sample code provided in <a href="https://gamandelkowcharts.codeplex.com/" rel="nofollow noreferrer">https://gamandelkowcharts.codeplex.com/</a>.</p>
  
  <p>Anyone knows a way to solve this? </p>
