Setting Title on Amcharts Windows QuickCharts serialChart / SerialGraph

Question

Hello,
I have an unexpected problem with SerialGraph Title text. I populate the text dynamically in codebehind. It seems that the text shown in Legend sticks to the first assigned value, and does not update. Tapping the graph shows correct content in tooltip. I
have tried to explicitly set the text = "" before updating the right content, no help.
(WP8 AmCharts runtime version v2.0.50727).
The chart is defined in XAML like
<Grid>
<!--LineChart-->
<chart:SerialChart x:Name="refAltChart"
Height="290" Width="460"
CategoryValueMemberPath="XPT"
AxisForeground="White"
PlotAreaBackground="Black"
Foreground="LightGray">
<chart:SerialChart.Graphs>
<chart:LineGraph Title="Altitude" ValueMemberPath="L1" Brush="Gray" StrokeThickness="1"/>
</chart:SerialChart.Graphs>
</chart:SerialChart>
</Grid>
X and Y axis values come from ObservableCollection<LineData> in codebehind and are updated correctly. Only the Legend (Graphs[0].Title) text does not update (the value preset in XAML is changed once and sticks to it).
AltChart.DataSource = TR_buildAltCollection(g_actTrkcls);
AltChart.Graphs[0].Title = string.Format("Y [{0}] @ X [{1}]", altfmt.ToString(), "m");
Is there any way I could "refresh" the Legend or Chart to fix this?

Hi kjkoo,

I can reproduce your issue in my side. I will try to do further testing and consult to see if there is any workaround.
