Hello,

Thank you for your post. I have been looking into it, but since I cannot be completely sure how your data is organized I wasn’t able to reproduce your behavior, so if this is still an issue for you, could you please send an isolated sample project, where the issue is reproduced, so I can investigate it further for you.

Looking forward for your reply.

I facing same problem with infragistics xamWebChart. When my observable collection changes chart does not change.

<XXX>.Xaml.CS

     <Viewbox Grid.Row="2" x:Name="vbIncidentStatus" Visibility="{Binding Path=IncidentStatusData, Converter={StaticResource StatusDataConverter}}" >
                <igChart:XamWebChart x:Name="igPieChart_IncidentStatus" Height="100" RefreshEnabled="True">
                    <igChart:XamWebChart.Scene>
                        <igChart:Scene Margin="-50,-20,-20,-20" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch"></igChart:Scene>
                    </igChart:XamWebChart.Scene>
                    
                    <igChart:XamWebChart.Series>
                        <!--DataMapping="Label=ToolTip; Value=CaseCount; ToolTip=ToolTip; Fill=SeverityGraphBrush"-->
                        <igChart:Series ChartType="Doughnut" 
                                        DataSource="{Binding  IncidentStatusData}" 
                                        DataMapping="Value=CaseCount;Label=ToolTip;ToolTip=ToolTip" Stroke= "White" Loaded="Series_Loaded">
                        </igChart:Series>
                    </igChart:XamWebChart.Series>
                    
                    <igChart:XamWebChart.Legend>
                        <igChart:Legend Width="0" Visibility="Collapsed"></igChart:Legend>
                    </igChart:XamWebChart.Legend>
                </igChart:XamWebChart>
            </Viewbox>

<xxxViewModel>.cs

                ObservableCollection<IncidentStatusData> _data = new ObservableCollection<IncidentStatusData>();
 
                int osrCount = 0;
              
                foreach (GetIncidentStatusResponseList itemIncStatus in incstatusDataCollection)
                {
               
                    IncidentStatusData _singleData = new IncidentStatusData();
                    _singleData.SeverityLevel = itemIncStatus.SeverityLevel;
                    _singleData.CaseCount = itemIncStatus.CaseCount;
                    _singleData.ToolTip = itemIncStatus.SeverityLevel + " (" + itemIncStatus.CaseCount + ")";
                    _singleData.SeverityGraphBrush = OISUtility.OISColours.getSeverityGraphBrush(itemIncStatus.SeverityLevel);
 
                     _data.Add(_singleData);
 
                    osrCount = osrCount + (int)itemIncStatus.CaseCount;
                }
 
                this.IncidentStatusModel.IncidentStatusData = _data;

 Kindly suggest me solution for this issue.

Hi,

Do you think you could provide a small code sample that replicates the issue? Some more details about how you are trying to set up the binding would help.

Thanks,

Graham
