如何使用WPFToolKit Chart

private void button1_Click(object sender, EventArgs e)

{

    var s = new Series();

    s.ChartType = SeriesChartType.Line;

    var d = new DateTime(2013, 04, 01);

    s.Points.AddXY(d, 3);

    s.Points.AddXY(d.AddMonths(-1), 2);

    s.Points.AddXY(d.AddMonths(-2), 1);

    s.Points.AddXY(d.AddMonths(-3), 4);

    chart1.Series.Clear();

    chart1.Series.Add(s);

    chart1.Series[0].XValueType = ChartValueType.DateTime;

    chart1.ChartAreas[0].AxisX.LabelStyle.Format = "yyyy-MM-dd";

    chart1.ChartAreas[0].AxisX.Interval = 1;

    chart1.ChartAreas[0].AxisX.IntervalType = DateTimeIntervalType.Months;

    chart1.ChartAreas[0].AxisX.IntervalOffset = 1;

    chart1.Series[0].XValueType = ChartValueType.DateTime;

    DateTime minDate = new DateTime(2013, 01, 01).AddSeconds(-1);

    DateTime maxDate = new DateTime(2013, 05, 01); // or DateTime.Now;

    chart1.ChartAreas[0].AxisX.Minimum = minDate.ToOADate();

    chart1.ChartAreas[0].AxisX.Maximum = maxDate.ToOADate();

}

或者

<charting:Chart x:Name="chtSummary" Width="770" Height="400" Title="My Chart Title">

<charting:Chart.TitleStyle>

 <Style TargetType="datavis:Title">

 <Setter Property="FontSize" Value="28" />

 <Setter Property="FontFamily" Value="Arial" />

 <Setter Property="Margin" Value="5, 10, 5, 15" />

 </Style> </charting:Chart.TitleStyle>

 <charting:Chart.LegendStyle>

 <Style TargetType="datavis:Legend">

 <Setter Property="Width" Value="0" />

 </Style> </charting:Chart.LegendStyle>

 <charting:Chart.Series>

 <charting:BarSeries ItemsSource="{Binding}" DependentValuePath="Value" IndependentValuePath="Key" IsSelectionEnabled="True" >

 <charting:BarSeries.IndependentAxis>

 <charting:CategoryAxis Orientation="Y" AxisLabelStyle="{StaticResource SummaryChartAxisStyle}" />

 </charting:BarSeries.IndependentAxis>

 </charting:BarSeries>

 </charting:Chart.Series>

</charting:Chart>

隐藏Legend

隐藏Chart的Legend

<chartingToolkit:Chart.LegendStyle>

    <Style TargetType="Control">

        <Setter Property="Width" Value="0" />

        <Setter Property="Height" Value="0" />

    </Style>

</chartingToolkit:Chart.LegendStyle>

隐藏具体Item的legend

<charting:LineSeries.LegendItemStyle >

  <Style TargetType="{x:Type charting:LegendItem}">

     <Setter Property="Visibility" Value="Collapsed"/>

  </Style>

</charting:LineSeries.LegendItemStyle>

显示定义横纵坐标

<Grid Height="800">

        <chartingToolkit:Chart  Name="lineChart" Title="Pressure over Time"

    VerticalAlignment="Top" Margin="20,50,20,0" Height="500">

            <chartingToolkit:Chart.Axes>

                <chartingToolkit:LinearAxis Title="Pressure" Orientation="Y" Interval="100" />

                <chartingToolkit:LinearAxis Title="Time" Orientation="X" Interval="100" />

            </chartingToolkit:Chart.Axes>

            <chartingToolkit:LineSeries DependentValuePath="Value" IndependentValuePath="Key" ItemsSource="{Binding}"  Name="Test"

                                        IsSelectionEnabled="True" ClipToBounds="False">

            </chartingToolkit:LineSeries>        </chartingToolkit:Chart>

        <Button Width="100" Height="24" Margin="20,556,1058,220" Content="More" Name="Button1" />

    </Grid>

修改横纵坐标

坐标值倒序排列

public class InverterConverter : IValueConverter

{

    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)

    {

        if (value is int)

        {

            return -(int)value;

        }

        throw new NotImplementedException();

    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)

    {

        throw new NotImplementedException();

    }

}

<charting:Chart

    FontSize="9">

    <charting:LineSeries

        ItemsSource="{Binding}"

        DependentValueBinding="{Binding Place, Converter={StaticResource InverterConverter}}"

        IndependentValuePath="Date"

        Title="Book">

        <charting:LineSeries.DataPointStyle>

            <Style TargetType="charting:LineDataPoint">

                <Setter Property="Background" Value="Maroon"/>

                <Setter Property="DependentValueStringFormat" Value="{}{0:0.#;0.#}"/>

            </Style>

        </charting:LineSeries.DataPointStyle>

        <charting:LineSeries.DependentRangeAxis>

            <charting:LinearAxis

                Orientation="Y"

                Minimum="-10.5"

                Maximum="-0.5"

                Interval="1"

                ShowGridLines="True">

                <charting:LinearAxis.AxisLabelStyle>

                    <Style TargetType="charting:AxisLabel">

                        <Setter Property="StringFormat" Value="{}{0:0.#;0.#}"/>

                    </Style>

                </charting:LinearAxis.AxisLabelStyle>

            </charting:LinearAxis>

        </charting:LineSeries.DependentRangeAxis>

    </charting:LineSeries>

</charting:Chart>

修改ToolTips

<ToolTipService.ToolTip>

    <StackPanel>

        <ContentControl

            Content="Custom ToolTip"

            FontWeight="Bold"/>
