Hi YXJ, 

 

We have checked the provided sample and we would like to let you know that you can improve the performance of the chart by removing the data marker from the chart series. Instead of datamarker we suggest to add the FastScatterBitmapSeries and set ShapeType as Triangle as shown in the below code snippet. 

 

LineControl.xaml 

<syncfusion:FastLineBitmapSeries XBindingPath="Name" 

                                     YBindingPath="Value" 

                                     StrokeDashArray ="3,3" 

                                     Interior="Red" 

                                     ListenPropertyChange="True" 

                                     ItemsSource="{Binding Data1}"> 

                <syncfusion:FastLineBitmapSeries.AdornmentsInfo> 

                    <syncfusion:ChartAdornmentInfo ShowMarker="True" SymbolInterior="Red" Symbol="Ellipse"> 

                    </syncfusion:ChartAdornmentInfo> 

                </syncfusion:FastLineBitmapSeries.AdornmentsInfo> 

            </syncfusion:FastLineBitmapSeries> 

            <syncfusion:FastScatterBitmapSeries  

                        XBindingPath="Name" 

                        YBindingPath="Value" 

                        Interior="Red"  

                        ScatterHeight="11"  

                        ScatterWidth="11" 

                        ShapeType="Triangle" 

                        ListenPropertyChange="True" 

                        ItemsSource="{Binding Data1}"> 

            </syncfusion:FastScatterBitmapSeries> 

 

Please see below sample for your reference.

Hi.

If i want to use 'ListenPropertyChange="True"' for line series, how to improve its performance?

[Manivannan Elangovan]

Hi YXJ,

To improve performance, we recommend for using FastLineSeries instead of regular LineSeries and also performance is not affected if you update the single data point value with enabling the ListenPropertyChange. ​

When bulk of data is updated, there is a lag in performance. In this case, you can use the SuspendedSeriesNotification before update the data and again call the ResumeSeriesNotification method. For more details please refer the below UG link.

Hi,

I need data marker for line series.

Can  FastLineSeries meet my needs?

[Manivannan Elangovan]

Hi YXJ,

FastLineSeries have data marker support but it will lag the performance while zooming and panning the chart area and also at load time when loading the large number of data. Instead of data marker you can use FastScatterBitmapSeries with ShapeType property.

Hi,

Thanks for your reply.

However, i need both data marker and line, so do you have any other advice

[Yuvaraj Palanisamy]

Hi YXJ,  

  

While using data marker(ChartAdornment) with FastLineSeries, it lags the performance of chart. Hence, as we suggested to use the FastScatterSeries instead of data marker.  

 

Could you please share us your exact use case scenario of data marker with FastLineSeries in a pictorial representation or a video with detailed information which will be helpful us to provide better solution at the earliest.  

 

Regards, 

Yuvaraj.

Hi YXJ, 

 

We have checked the provided sample and found that using LineSeries with ChartAdornment. As we suggested earlier, we recommend FastLineSeries and you can use FastScatterBitmapSeries instead of the data marker for better performance. 

 

Please refer the below code example using FastLineSeries and FastScatterBitmapSeries as the line series data marker. 

 

LineControl.xaml 

<syncfusion:FastLineSeries StrokeDashArray="3,5" 

            XBindingPath="Name" 

            YBindingPath="Value" 

            Interior="Red"  

            ListenPropertyChange="True" 

            ItemsSource="{Binding Data6}"> 

    <syncfusion:LineSeries.AdornmentsInfo> 

        <syncfusion:ChartAdornmentInfo 

            ShowMarker="True" 

            Symbol="Ellipse"> 

        </syncfusion:ChartAdornmentInfo> 

    </syncfusion:LineSeries.AdornmentsInfo> 

</syncfusion:FastLineSeries> 

<syncfusion:FastScatterBitmapSeries   

            XBindingPath="Name"  

            YBindingPath="Value"  

            Interior="Red"  

            ScatterHeight="11"   

            ScatterWidth="11"  

            ShapeType="Ellipse"  

            ListenPropertyChange="True"  

            ItemsSource="{Binding Data6}"> 

</syncfusion:FastScatterBitmapSeries> 

 

Please see below sample for your reference.
