Chart Tooltip
posted

Ok, What's missing,

I've followed the tutorial for tooltip and I was not able to see it in my splineareaseries chart.  I copied the code from the tutrorial directly off the page to a new app and I was still unable to see the tooltip in the chart using the tap and hold.   Please Assist.

    Hi,

    Here you have an example of tooltip in a SplineAreaSeries:

        <Grid x:Name="LayoutRoot" Background="Transparent"
          DataContext="{StaticResource DataViewModel}">
        <ig:XamDataChart x:Name="xamSplineAreaChart"
                         HorizontalZoomable="True" VerticalZoomable="True" 
                         HorizontalAlignment="Stretch" VerticalAlignment="Stretch"
                         CrosshairVisibility="Visible">
            <ig:XamDataChart.Axes>
                <ig:NumericYAxis x:Name="SplineAreaYAxis" MinimumValue="0" Interval="200" />
                <ig:CategoryXAxis x:Name="SplineAreaXAxis" ItemsSource="{Binding EnergySampleData}" />
            </ig:XamDataChart.Axes>
            <ig:XamDataChart.Series>
                <ig:SplineAreaSeries ItemsSource="{Binding EnergySampleData}" ValueMemberPath="Coal"
                                     Title="{Binding StringEnergyCoal, Source={StaticResource DataViewModel}}"
                                     XAxis="{Binding ElementName=SplineAreaXAxis}"
                                     YAxis="{Binding ElementName=SplineAreaYAxis}">
                    <ig:SplineAreaSeries.ToolTip>
                        <TextBlock Text="{Binding Item.Coal}" />
                    </ig:SplineAreaSeries.ToolTip>
                </ig:SplineAreaSeries>
                <ig:SplineAreaSeries ItemsSource="{Binding EnergySampleData}" ValueMemberPath="Hydro"
                                     Title="{Binding StringEnergyHydro, Source={StaticResource DataViewModel}}"
                                     XAxis="{Binding ElementName=SplineAreaXAxis}"
                                     YAxis="{Binding ElementName=SplineAreaYAxis}">
                    <ig:SplineAreaSeries.ToolTip>
                        <TextBlock Text="{Binding Item.Hydro}" />
                    </ig:SplineAreaSeries.ToolTip>
                </ig:SplineAreaSeries>
            </ig:XamDataChart.Series>
        </ig:XamDataChart>
    </Grid>

    Regards,

    Luis.
