[Atif]

Hi please guide me is there any way to filter chart at run time with Daily( Hourly), Weekly, Monthly, Yearly.

Hi Atif, 

 

Thanks for contacting Syncfusion support. 

 

We could filter SfChart by dynamically updating its data source. We have prepared a sample for this and it can be downloaded in below link. 

 

Chart Sample 

 

The DateTime Range Navigator control provides an intuitive interface for selecting a smaller date range from a larger collection. To filter the date range in wide range of chart data we could use SfDateTimeRangeNavigator control.

Please let us know for any concerns.

Nice i got the solution, Only one problem i am facing i have my own custom Carousel control and i used content Views inside Carousel and when chart bind with data i am not able to swipe left and swipe right if there is no data in graph inverting works perfect.

Hi Atif,  

 

We have analyzed the reported requirement and achieved your requirement by a workaround. In the workaround sample, we can get the Native SFChart object from AppDelegate class in iOS project here, to customize the chart pan gesture to handle the Carousel view as shown in the below code example. 

 

Code snippet : 

 

Xamarin.Forms.Forms.ViewInitialized += (sender, e) => 

{ 

        SFChart chart = (e.NativeView as SFChart); 

 

        if (chart != null) 

        { 

               foreach (var gesture in chart.GestureRecognizers) 

               { 

                    if (gesture is UIPanGestureRecognizer && gesture.Delegate == null) 

                    { 

                          gesture.Delegate = new CustomGeatureDelegate(e.View as SfChart); 

                    } 

                } 

        } 

}; 

 

We have overridden the UIGestureRecognizerDelegate class and with help of its ShouldBegin method. The customized delegate object has been assigned to chart’s UIPanGestureRecognizer’s delegate property. 

 

We have prepared a sample based on your requirement. Please find the sample from the following link.

Please let us know if you have any other query.

Didn't work, Is there any easy way to detect the swap left and right gestures on graph if it is available then it would help my cause.

Thanks

Hi Atif, 

 

Could you please clarify us whether the sample we gave in our last update is working?  

 

Also, please share us the sample with your custom Carousal control using SfChart to reproduce the issue which would be more helpful for us to serve you better.

Hi Atif,

We have modified the sample as per your requirement. In this sample, we have passed the touch move action to the parent (ScrollView) and handled the tap event in Chart.

Please download the sample from the below location.
