Basically I have a chart with multiple bar series. The independent value for all the series are the same. So the chart's xaxes are rendered with stacked of same independent values.
If I want to make all series (except for the first one) xaxes' labels to not visible, how can i do that in the xaml declaration?
Can anyone please give me assistance on this?
Update:
I have come across example with the following code:
<toolkit:Chart x:Name="myChart" Width="600" Height="400">
<toolkit:LineSeries
Title="Tasks"
ItemsSource="{Binding}"
IndependentValueBinding="{Binding Month}"
DependentValueBinding="{Binding Task}">
</toolkit:LineSeries>
<toolkit:LineSeries
Title="Benefits"
ItemsSource="{Binding}"
IndependentValueBinding="{Binding Month}"
DependentValueBinding="{Binding Benefits}">
</toolkit:LineSeries>
<toolkit:Chart.Axes>
<toolkit:LinearAxis Orientation="Y" Location="Left" Title="First" />
<toolkit:LinearAxis Orientation="Y" Location="Right" Title="Second" />
</toolkit:Chart.Axes>
</toolkit:Chart>
If you plot the above code, you will see that both series will base the Y values from the left one. How can we change it so that first series will be plotted against Y values on the left and second series to be plotted against Y values on the right.
is that possible?
Thanks.
I think you can achieve what you want using the DependentRangeAxis properties of the LineSeries objects.
First, give each Y-axis an x:Name, for example TaskAxis and BenefitsAxis.
Then, you can tell a LineSeries to use an axis by adding to it the property
DependentRangeAxis="{Binding ElementName=TaskAxis}"
or
DependentRangeAxis="{Binding ElementName=BenefitsAxis}"
as appropriate.
The full XAML of the chart then becomes
<toolkit:Chart x:Name="myChart" Width="600" Height="400">
<toolkit:LineSeries
Title="Tasks"
ItemsSource="{Binding Path=Data1}"
IndependentValueBinding="{Binding Month}"
DependentValueBinding="{Binding Task}"
DependentRangeAxis="{Binding ElementName=TaskAxis}">
</toolkit:LineSeries>
<toolkit:LineSeries
Title="Benefits"
ItemsSource="{Binding Path=Data1}"
IndependentValueBinding="{Binding Month}"
DependentValueBinding="{Binding Benefits}"
DependentRangeAxis="{Binding ElementName=BenefitsAxis}">
</toolkit:LineSeries>
<toolkit:Chart.Axes>
<toolkit:LinearAxis Orientation="Y" Location="Left" Title="First" x:Name="TaskAxis" />
<toolkit:LinearAxis Orientation="Y" Location="Right" Title="Second" x:Name="BenefitsAxis" />
</toolkit:Chart.Axes>
</toolkit:Chart>
Another approach is to move the Axis objects inside the LineSeries. A demonstration of how to do this can be found here.

total emergency here. Just saw WPF for the first time and need this quick, so forgive me: if I don't provide enough info first time around I promise to edit the question.
In a charting object, defined with namespace:
xmlns:charting="clr-namespace:System.Windows.Controls.DataVisualization.Charting;assembly=System.Windows.Controls.DataVisualization.Toolkit"
I am drawing a simple bar chart.
<charting:Chart Grid.Row="2" Grid.Column="0" Grid.ColumnSpan="3"
Visibility="{Binding Path=MyCurrentResultsView, Converter={StaticResource ResourceKey=NullObjectToVisibilityConverter}}"
Background="Transparent" Foreground="White"
Margin="50,0,50,0" Height="350"
HorizontalAlignment="Stretch" Title="{Binding Path=MyCurrentResultsView.Name}">
<charting:ColumnSeries Height="350" Foreground="Black"
ItemsSource="{Binding Path=MyCurrentResultsView.ResultsView}"
IndependentValueBinding="{Binding Key}"
DependentValueBinding="{Binding Value}">
</charting:ColumnSeries>
</charting:Chart>
What I'd like to do is to show the value of each column above the column (or even inside the column rectangle if possible: these are percentage values and the idea is to make them more visible on the bar chart).
I have been looking at the styling information, but here this is more than just style. I see two possibilities. Either:
For each column item in the series, define a transformation that positions a frame above each column, creates a text box whose label is set to the dependent value, then draws the text box inside the frame.
Find some kind of property on "ColumnSeries" or "? ColumnItem ?" that "enables" the display of the bound value above the column.
Total shot in the dark here. Thanks.
I would try to change the ColumnDatapointTemplate like this:
<charting:ColumnSeries Height="350" Foreground="Black"
ItemsSource="{Binding Path=MyCurrentResultsView.ResultsView}"
IndependentValueBinding="{Binding Key}"
DependentValueBinding="{Binding Value}">
<charting:ColumnSeries.DataPointStyle>
<Style TargetType="charting:ColumnDataPoint">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="charting:ColumnDataPoint">
<Grid>
<Rectangle Fill="{TemplateBinding Background}" Stroke="Black"/>
<Grid Margin="0 -20 0 0" HorizontalAlignment="Center" VerticalAlignment="Top">
<TextBlock Text="{TemplateBinding FormattedDependentValue}" Margin="2"/>
</Grid>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</charting:ColumnSeries.DataPointStyle>
</charting:ColumnSeries>
Play a bit with vertical alignments and/or margins and you will be able to get infos into the columns and other.
Hope this help!
I have created a DVC:Chart as shown below in my code, how do i add x-axis and y-axis labels to the chart?
<DVC:Chart Name="callLogs"
Background="SteelBlue" Grid.ColumnSpan="2">
<DVC:Chart.Series>
<DVC:ColumnSeries Title="Calls per Hour"
IndependentValueBinding="{Binding Path=Key}"
DependentValueBinding="{Binding Path=Value}">
</DVC:ColumnSeries>
</DVC:Chart.Series>
</DVC:Chart>
Thanks in advance
I have managed to figure it out:
<DVC:Chart Name="callLogs"
Background="SteelBlue" Grid.ColumnSpan="2">
<DVC:Chart.Axes>
<DVC:LinearAxis Orientation="Y" Title="Ammount of calls"/>
<DVC:LinearAxis Orientation="X" Title="Time (Hours)"/>
</DVC:Chart.Axes>
<DVC:Chart.Series>
<DVC:ColumnSeries Title="Calls per Hour"
IndependentValueBinding="{Binding Path=Key}"
DependentValueBinding="{Binding Path=Value}">
</DVC:ColumnSeries>
</DVC:Chart.Series>
</DVC:Chart>
However, its labeling my x-axis for me, don't know how to customize it, so i will post the new solution when i figure it out.
I'm using the chart control from the WPF Toolkit. How can I set the interval of the X axis?
I have the following XAML code:
<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>
The Y Axis works fine, it shows the interval of 100 but the X axis puts itself on the top (please see the added image) and the interval is the exact amounts of points. Why doesnt it listen to the Interval="100" property in the xaml? And why doesn't it place itself on the bottom?
For the location of the linearAxis, you can set the Location property to "Bottom"
in code:
<chartingToolkit:LinearAxis Title="Time" Orientation="X" Interval="100"
Location="Bottom" />
For the interval problem, i don't know...
I am having problem to show the grid in a way that I wanted. But I am also not sure whether it is possible to do that in the Silverlight toolkit chart. So any help or direction on this would be appreciated.
<Grid x:Name="LayoutRoot" Background="White">
<charting:Chart x:Name="myChart" Width="600" Height="400">
<charting:BarSeries
Title="Tasks"
ItemsSource="{Binding Path=Data1}"
IndependentValueBinding="{Binding Month}"
DependentValueBinding="{Binding Task}"
DependentRangeAxis="{Binding ElementName=TaskAxis}">
</charting:BarSeries>
<charting:LineSeries
Title="Benefits"
ItemsSource="{Binding Path=Data1}"
IndependentValueBinding="{Binding Month}"
DependentValueBinding="{Binding Benefits}"
DependentRangeAxis="{Binding ElementName=BenefitsAxis}">
</charting:LineSeries>
<charting:Chart.Axes>
<charting:LinearAxis Orientation="Y" Location="Left" Title="First" x:Name="TaskAxis" />
<charting:LinearAxis Orientation="Y" Location="Right" Title="Second" x:Name="BenefitsAxis" />
</charting:Chart.Axes>
</charting:Chart>
</Grid>
Given the above snippet, is it possible to have the Yaxis on the left to show the month and the top x-axis to show the tasks value, and bottom x-axis to show the benefits value.
So in a way, it is sharing the Yaxis for the month. and it can use either top/bottom x-axis or even right Yaxis to plot the tasks and benefits value.
What do you guys think?
Thanks.
The example below has the task axis on the top and the benefits axis on the bottom, with a shared Y-axis on the left:
<toolkit:Chart x:Name="myChart" Width="600" Height="800">
<toolkit:BarSeries
Title="Tasks"
ItemsSource="{Binding Path=Data1}"
IndependentValueBinding="{Binding Month}"
DependentValueBinding="{Binding Task}"
DependentRangeAxis="{Binding ElementName=TaskAxis}">
</toolkit:BarSeries>
<toolkit:BarSeries
Title="Benefits"
ItemsSource="{Binding Path=Data1}"
IndependentValueBinding="{Binding Month}"
DependentValueBinding="{Binding Benefits}"
DependentRangeAxis="{Binding ElementName=BenefitsAxis}">
</toolkit:BarSeries>
<toolkit:Chart.Axes>
<toolkit:LinearAxis Orientation="X" Location="Top" Title="Task" x:Name="TaskAxis" />
<toolkit:LinearAxis Orientation="X" Location="Bottom" Title="Benefits" x:Name="BenefitsAxis" />
</toolkit:Chart.Axes>
</toolkit:Chart>
i have problem to correctly bind data to WPF Chart. When i'm setting ItemsSource i get error:
Assigned dependent axis cannot be used. The data may not be able to be rendered on the provided axis or the series may require that they axis has an origin.
oc = new ObservableCollection<Pair>();
heartBeats.ItemsSource = oc;
to Pair i'm saving int and long
XAML:
...
xmlns:charting="clr-namespace:System.Windows.Controls.DataVisualization.Charting;assembly=System.Windows.Controls.DataVisualization.Toolkit" >
<charting:Chart x:Name="ApplicatioChart">
<charting:Chart.Series>
<charting:ColumnSeries x:Name="heartBeats" Title="Working Set"
DependentValueBinding="{Binding First}" IndependentValueBinding="{Binding Second}" >
<charting:ColumnSeries.IndependentAxis>
<charting:CategoryAxis Orientation="X" />
</charting:ColumnSeries.IndependentAxis>
<charting:ColumnSeries.DependentRangeAxis>
<charting:LinearAxis Orientation="Y" />
</charting:ColumnSeries.DependentRangeAxis>
</charting:ColumnSeries>
</charting:Chart.Series>
</charting:Chart>
Please help.. :(
i resolved it this way:
<charting:Chart Title="Engine Performance" x:Name="ApplicationChart">
<!-- Power curve -->
<charting:LineSeries x:Name="heartBeats"
Title="ManagedHeapSize"
IndependentValueBinding="{Binding EventTime}"
DependentValueBinding="{Binding ManagedHeapSize}">
<!-- Vertical axis -->
<charting:LineSeries.DependentRangeAxis>
<charting:LinearAxis
Orientation="Y"
Title="ManagedHeapSize"
Interval="10000000" Focusable="True"
ShowGridLines="True"/>
</charting:LineSeries.DependentRangeAxis>
</charting:LineSeries>
<charting:Chart.Axes>
<!-- Shared horizontal axis -->
<charting:LinearAxis
Orientation="X"
Title="EventTime"
Interval="100"
ShowGridLines="True"/>
</charting:Chart.Axes>
</charting:Chart>
Can't see anything wrong with the mark up (apart from the same Property being bound as both the dependent and independent value).
It seems to work fine in the Silverlight version, I don't have the WPF version to play with.
Try removing the definition for the DependentRangeAxis, to see whether it works with the default one.
