the Series binding update problem

Aug 9, 2014 at 2:43 PM
I use Series binding on WP 8
something like

<sparrow:SparrowChart Series="{Binding ChartSeries}" >
<sparrow:SparrowChart.XAxis>
<sparrow:DateTimeXAxis>
</sparrow:SparrowChart.XAxis>
<sparrow:SparrowChart.YAxis>
<sparrow:LinearYAxis/>
</sparrow:SparrowChart.YAxis>
</sparrow:SparrowChart>

if I have the data already when I load the page , it works fine
but when i update the data, the axis update the Series disapper.
the chart becomes empty.

I found the discussion https://sparrowtoolkit.codeplex.com/discussions/445161

"I tried to run GenerateConatiners evry time when collection changed and this solved my problem, but I want updated nuget package with normal bug fix. "

but there is no GenerateConatiners function and I found refresh()
but how can i use this?

thanks so much !!!
