new hand ask question:how to set background like this pic?
You can use a template to re-style the chart's grid. Here's an example:
<ig:XamChart Name="chart"> <ig:XamChart.Legend> <ig:Legend Visible="False"/> </ig:XamChart.Legend> <ig:XamChart.Axes> <ig:Axis AxisType="PrimaryX"> <ig:Axis.MajorGridline> <ig:Mark Visible="False"/> </ig:Axis.MajorGridline> </ig:Axis> <ig:Axis AxisType="PrimaryY" Unit="2"/> </ig:XamChart.Axes> <ig:XamChart.Series> <ig:Series ChartType="Line" Fill="Black"> <ig:Series.Marker> <ig:Marker Format=" "/> </ig:Series.Marker> <ig:Series.DataPoints> <ig:DataPoint Value="1"/> <ig:DataPoint Value="3"/> <ig:DataPoint Value="6"/> <ig:DataPoint Value="4"/> <ig:DataPoint Value="7"/> <ig:DataPoint Value="9"/> <ig:DataPoint Value="3"/> </ig:Series.DataPoints> </ig:Series> </ig:XamChart.Series> <ig:XamChart.Scene> <ig:Scene> <ig:Scene.GridArea> <ig:GridArea> <ig:GridArea.Template> <ControlTemplate TargetType="ig:GridArea"> <Grid> <Grid> <Grid.RowDefinitions> <RowDefinition/> <RowDefinition/> <RowDefinition/> <RowDefinition/> <RowDefinition/> <RowDefinition/> </Grid.RowDefinitions> <Border Background="Red" Grid.Row="0"/> <Border Background="Yellow" Grid.Row="1"/> <Border Background="Lime" Grid.Row="2"/> <Border Background="Lime" Grid.Row="3"/> <Border Background="Yellow" Grid.Row="4"/> <Border Background="Red" Grid.Row="5"/> </Grid> <ContentPresenter/> </Grid> </ControlTemplate> </ig:GridArea.Template> </ig:GridArea> </ig:Scene.GridArea> </ig:Scene> </ig:XamChart.Scene></ig:XamChart>
i so glod you can answer my question.first ,other question is no line and no cicle.
thanks again you patience,by the way ,i want the lable like that chart:
<Grid x:Name="LayoutRoot"> <igWebChart:XamWebChart HorizontalAlignment="Left" Name="xamWebChart1" VerticalAlignment="Top" > <igWebChart:XamWebChart.Legend> <igWebChart:Legend Visibility="Collapsed"> </igWebChart:Legend> </igWebChart:XamWebChart.Legend> <igWebChart:XamWebChart.Axes> <igWebChart:Axis AxisType="PrimaryX"> <igWebChart:Axis.MajorGridline> <igWebChart:GridlineGroup Visibility="Visible"> </igWebChart:GridlineGroup> </igWebChart:Axis.MajorGridline> </igWebChart:Axis> <igWebChart:Axis AxisType="PrimaryY" Unit="2"> </igWebChart:Axis> </igWebChart:XamWebChart.Axes> <igWebChart:XamWebChart.Series> <igWebChart:Series ChartType="Line" Fill="Black" Opacity="1" > <igWebChart:Series.Marker> <igWebChart:Marker Format="" Type="Circle" ></igWebChart:Marker> </igWebChart:Series.Marker> <igWebChart:Series.DataPoints> <igWebChart:DataPoint Value="1" Label="a"/> <igWebChart:DataPoint Value="4" Label="b"/> <igWebChart:DataPoint Value="6" Label="c"/> <igWebChart:DataPoint Value="11" Label="d"/> <igWebChart:DataPoint Value="7" Label="e"/> <igWebChart:DataPoint Value="19" Label="f"/> </igWebChart:Series.DataPoints> </igWebChart:Series> </igWebChart:XamWebChart.Series> <igWebChart:XamWebChart.Scene> <igWebChart:Scene> <igWebChart:Scene.GridArea> <igWebChart:GridArea> <igWebChart:GridArea.Template> <ControlTemplate TargetType="igWebChart:GridArea"> <Grid> <Grid> <Grid.RowDefinitions> <RowDefinition/> <RowDefinition/> <RowDefinition/> <RowDefinition/> <RowDefinition/> <RowDefinition/> </Grid.RowDefinitions> <Border Background="Red" Grid.Row="0"/> <Border Background="Yellow" Grid.Row="1"/> <Border Background="Lime" Grid.Row="2"/> <Border Background="Lime" Grid.Row="3"/> <Border Background="Yellow" Grid.Row="4"/> <Border Background="Red" Grid.Row="5"/> </Grid> <ContentPresenter/> </Grid> </ControlTemplate> </igWebChart:GridArea.Template> </igWebChart:GridArea> </igWebChart:Scene.GridArea> </igWebChart:Scene> </igWebChart:XamWebChart.Scene> </igWebChart:XamWebChart>
The template will work for the WPF chart, but not for Silverlight. For the silverlight chart, you have to modify the template to use a Canvas instead of a ContentPresenter:<ControlTemplate TargetType="igWebChart:GridArea"> <Grid> <Grid> <Grid.RowDefinitions> <RowDefinition/> <RowDefinition/> <RowDefinition/> <RowDefinition/> <RowDefinition/> <RowDefinition/> </Grid.RowDefinitions> <Border Background="Red" Grid.Row="0" /> <Border Background="Yellow" Grid.Row="1" /> <Border Background="Lime" Grid.Row="2"/> <Border Background="Lime" Grid.Row="3"/> <Border Background="Yellow" Grid.Row="4"/> <Border Background="Red" Grid.Row="5" /> </Grid> <Canvas Name="RootElement"/> </Grid></ControlTemplate>
The labels can be rotated like this:<igWebChart:Axis AxisType="PrimaryX"> <igWebChart:Axis.Label> <igWebChart:LabelGroup Angle="-70" DistanceFromAxis="6"/> </igWebChart:Axis.Label></igWebChart:Axis>
If you want dates for the labels, you can use those dates as label strings, when you add data points to the series.DataPoint Value="1" Label="10:45"
i have lot of question ,sorry ! ^_^
returnValue.ChartType = ChartType.Line;
if (yKey == "Result")
{
brush = new SolidColorBrush(Colors.Blue);
returnValue.Fill = brush;
}
else
write what?
1.the Result was middle line ,other line was dotted line ,what should i do .
2.when i set xamWebChartPkg.Axes[1].Unit = 0.001;
it warning:Yaxis unit value too small.
but i must set the unit with small,otherwise the space was too small.
i see,thanks for you patience again!
AutoRange should be set to False. Otherwise, Min, Max and Unit are automatically calculated.
mychart so ugly
<igWebChart:Axis AxisType="PrimaryY" Maximum="130" Minimum="20" AutoRange="True" Unit="30"> <igWebChart:Axis.Label> <igWebChart:LabelGroup Angle="-30" > </igWebChart:LabelGroup> </igWebChart:Axis.Label> <igWebChart:Axis.MajorGridline> <igWebChart:GridlineGroup Visibility="Visible" StrokeThickness="0"></igWebChart:GridlineGroup> </igWebChart:Axis.MajorGridline> </igWebChart:Axis> </igWebChart:XamWebChart.Axes>
how can i set the YAxes for datasource like MIN Max and so on .
when i selected second row
