Yvalue does not show on the graph after rebind

[Michael]

Hi Guys,

I am using wpf to create a live data reporting software. I used the radchart control to show the live line graph. Following is the example code:
xaml code:

<chart:RadChart x:Name="chart1" AxisElementBrush="#FFD43636">

<chart:RadChart.SeriesMappings>

<charting:SeriesMapping LegendLabel="Value">

<charting:SeriesMapping.SeriesDefinition>

<charting:LineSeriesDefinition ShowItemLabels="False"></charting:LineSeriesDefinition>

</charting:SeriesMapping.SeriesDefinition>

<charting:ItemMapping FieldName="index" DataPointMember="XValue"></charting:ItemMapping>

 <charting:ItemMapping FieldName="value" DataPointMember="YValue"></charting:ItemMapping>

 </charting:SeriesMapping>

 </chart:RadChart.SeriesMappings>

 </chart:RadChart>
Code_behind is:

List<indexsandnumbers> data = new List<indexandnumbers>();
for (int i = 1; i < 999999; i++)

{
   index = i;
   value = i*1.3;
   data.add(new indexsandnumbers(index,value));

   chart1.Itemsource = data;
   chart1.rebind();
}

However, I can only see the Xvalue increase and there is no Yvalue in the chart1 after I run the application.

The only way to show the line chart is I stop the loop, I can not get the line chart during the loop.

Any helps is appreciated.


Thank you very much.

Hi Michael,

Have you seen the online demos regarding the live performance of RadChart?
