WPF Elements Chart Question

We are developing a product which can quickly plot some transit character charts for our client

1. As you can see from attached picture barchart1 – riders by gender, I have three category values in the List, but the horizontal X axis of bar chart showed redundant categories/labels, I assigned the same variable to Pie chart pie series ItemsSource, it’s working fine.
2. As I set the ItemsSource to another variable for the barchart bar series (vehicles in household - attached picture barchart2), the horizontal axis retained some previous category values, again the pie chart works fine piechart2
3. Piechart3how do I quickly get a more differential color schemes, because the number of routes are a lot.
4. Regarding the actual number value in the bar chart, how do I set it show as Integer?

The XAML code for the bar/pie charts

                <ms:Chart x:Name="barChart2" Title="Howard Transit" MinHeight="350"  Grid.Row="1" 
                              Visibility="{Binding Path=IsChecked, ElementName=radioBarChart, 
                                Mode=OneWay, Converter={StaticResource visibilityConverter}}">
                    <ms:BarSeries Title="2011" ShowDataLabels="True" BarSizeFactor="0.4" />
                    <ms:Chart.BackgroundElements>
                        <ms:ChartGrid VerticalGridLineBrush="Transparent">
                            <ms:ChartGrid.HorizontalStripeBrushes>
                                <SolidColorBrush Color="Transparent" />
                                <SolidColorBrush Color="#EFEFEF" />
                            </ms:ChartGrid.HorizontalStripeBrushes>
                        </ms:ChartGrid>
                    </ms:Chart.BackgroundElements>
                    <ms:Chart.XAxis>
                        <ms:ChartAxis Style="{StaticResource AxisStyle}" />
                    </ms:Chart.XAxis>
                    <ms:Chart.YAxis>
                        <ms:ChartAxis MinorTickMarkVisibility="Visible"
                  Style="{StaticResource AxisStyle}" />
                    </ms:Chart.YAxis>
                </ms:Chart>                    


                <ms:PieChart x:Name="pieChart2" Title="Howard Transit" MinHeight="350"  Grid.Row="1"
                              Visibility="{Binding Path=IsChecked, ElementName=radioPieChart, 
                                Mode=OneWay, Converter={StaticResource visibilityConverter}}">
                    <ms:PieSeries Name="PieSeries" ShowDataLabels="True" ShowDataLabelLines="True" 
                                  DataLabelStyle="{StaticResource PercentageDataLabelStyle}" />
                </ms:PieChart>

In the code, depends on the user selection, I assign the ItemsSource.

        barChart2.Series[0].ItemsSource = valueList;

        pieChart2.Series[0].ItemsSource = valueList;

valueList is a List of StringDoubles

If you can help me out here, it’s greatly appreciated.

Thank you

Hello

I think you may need to get the latest nightly build. Nightly builds are published each night and contain small fixes or new features since the last major build. For the version you have, the nightly build will include almost a year of updates that you'll want. To get the latest nightly build, go to your account page http://www.mindscapehq.com/store/myaccount, click the green downloads button next to the Megapack, then find the nightly builds link next to WPF Elements 5.1. This should resolve number 1 and 2. Let me know if the issues remain.

3/ You can customize the palette of a pie chart by adding brushes to the PieSeries.Brushes collection. This can be done both in xaml and in code. Here is a xaml example:

<ms:PieSeries.Brushes>
  <SolidColorBrush Color="#98D0DE" />
  <SolidColorBrush Color="#CB5C5C" />
  <SolidColorBrush Color="#E99365" />
  <SolidColorBrush Color="#95CB96" />
  <SolidColorBrush Color="#F8D16D" />
</ms:PieSeries.Brushes>

4/ You can customize the look of the bar chart labels by setting the BarSeries.DataLabelStyle property. This style will be similar to what you did for showing percentages in the pie chart labels. Your percentage pie chart label style is probably using our FormattingConverter. If so, you can set the FormattingString property of a converter instance to be "{}{0:0}" to display as an integer.
