Xamarin andorid click on specific point in Spline area Graph.

Question

Hello. I was looking the Syncfusion Components mobile app and I found the possibility in a SplineAres Graph to click and display the specific value of that point. I attached also a zip file with a printscreen about what I mean. How can I do it, and how can I keep the value on screen longer?

Thank you very much.

Hi Konstantinos, 
 
Thanks for contacting Syncfusion support. 
 
Query 1: and I found the possibility in a SplineAres Graph to click and display the specific value of that point. I attached also a zip file with a printscreen about what I mean. How can I do it  
Your requirement to display the specific value of point on click can be achieved by enabling Tooltip as shown in the below code snippet. 
 
Code snippet [C#]: 




series.TooltipEnabled = true; 
 
Query 2: how can I keep the value on screen longer? 
You can set the Duration property of toolip as you required. Please refer the below code snippet. 
 
Code snippet [C#]: 




ChartTooltipBehavior tooltip = new ChartTooltipBehavior(); 
tooltip.Duration = 3600; 
chart.Behaviors.Add(tooltip); 
 
You can refer the following user guide link to know more about tooltip.
