Hi Graham,
Is it possible to put xamDataChart in ToolTip of another component? I try to place it in tooltips of textblock and it doesn't work. But if I use xamDataChart as usual it works fine.
Hi,
It should be possible. Could you share how you are trying to do it? I should be able to point out whats going wrong.

YAxis="{Binding ElementName=yAxisChartOI}"

</ig:ColumnSeries>
<ig:ColumnSeries x:Name="SeriesTest2"

</ig:XamDataChart.Series>
</ig:XamDataChart>
</TextBlock.ToolTip>
</TextBlock>
As a result I see only labels on xAxis. No series, no yAxis. When I put the same xamChart on main form I see nice chart as expected.
You run into some Namescope issues when trying to use elementname bindings in a tooltip, here's an alternate way to bind the series to the axes:
XAxis="{Binding RelativeSource={RelativeSource AncestorType=ig:XamDataChart, Mode=FindAncestor}, Path=Axes[(system:Int32)1]}" YAxis="{Binding RelativeSource={RelativeSource AncestorType=ig:XamDataChart, Mode=FindAncestor}, Path=Axes[(system:Int32)0]}"
This relies on this namespace being added to the root node:
xmlns:system="clr-namespace:System;assembly=mscorlib"
Hope this helps!
