Hello,
I am trying to show a StackedColumnSeries which will have in each column the same X number of data to be stacked.
What I want to do is to create dynamically each StackedFragmentSeries depending on the number of the data to be shown. I can't know the quantity because there will be different filters which will allow to pick different information from the database.
In the example below is my attempt to show it by binding the stackedFragmentSeries to an ObservableCollection, but it doesn't show anything. Emissions is the Observable collection with the values catched from the Database and they are Decimals. Any help about this?
<ig:XamDataChart x:Name="xamStackedColumnChart" Legend="{Binding ElementName=xmLegend}" Padding="10" Visibility="Visible" HorizontalZoomable="True" HorizontalZoombarVisibility="Collapsed" VerticalZoomable="True" VerticalZoombarVisibility="Collapsed" > <ig:XamDataChart.Axes> <ig:NumericYAxis x:Name="StackedColumnYAxis" MinimumValue="0" Interval="10000" Label="{}{} T CO2" MaximumValue="250000" LabelSettings="{StaticResource AxisLabelSettings2}"/> <ig:CategoryXAxis x:Name="StackedColumnXAxis" ItemsSource="{Binding ValuesOfExcessVSEmissions}" Label="{}{Date}" /> </ig:XamDataChart.Axes> <ig:XamDataChart.Series> <ig:StackedColumnSeries x:Name="StackedColumns" XAxis="{Binding ElementName=StackedColumnXAxis}" YAxis="{Binding ElementName=StackedColumnYAxis}" ItemsSource="{Binding ValuesOfExcessVSEmissions}"> <ig:StackedColumnSeries.Series> <ig:StackedFragmentSeries ValueMemberPath="Emissions" Title="{Binding ValuesOfExcessVSEmissions}"> </ig:StackedFragmentSeries> </ig:StackedColumnSeries.Series> </ig:StackedColumnSeries> </ig:XamDataChart.Series> </ig:XamDataChart>
Is there a way to do this without the "GroupBy" resource? We groupby in SQL, so this is not needed... but I can't figure out how to designate which field is the KeyMemberPath or ValueMemberPath.
Hello Michael,
I believe Rob has already answered this question here:
https://www.infragistics.com/community/forums/f/ultimate-ui-for-wpf/97084/xamdatachart-stackedcolumnseries-group-by-how-do-we-properly-set-the-tooltip-and-legend
Using the Sample above how do we properly format the Tooltip value?
Currently it is only displaying the value not the name.
Current Tooltip reads: Series Title: 7
Ideally we want: Emission: 7.
Thanks,
Michael
Using the sample above, how to we get the tooltip to provide meaningful text?
<igChart:StackedColumnSeries x:Name="stack"ItemsSource="{StaticResource grouped}" XAxis="{Binding ElementName=xAxis}" YAxis="{Binding ElementName=yAxis}" AutoGenerateSeries="True" ShowDefaultTooltip="True"></igChart:StackedColumnSeries>
See attached screenshot.
Got it now that I am awake. :-)
