I have two questions about Line Chart:

1-In Secondary Axis is possible have a string? 
Specifically i want to have Salaries in my Y point.
2-Is there a way to customise the Tooltip, and have a format like "(mYpointX - MypointY)"

Hi Charlin,


Thanks for using the Syncfusion products.


Query 1: In Secondary Axis is possible have a string?  Specifically I want to have Salaries in my Y point.


We are able to achieve your requirement by using chart axis LabelCreated event. Please refer KB from the following location.

Query2: Customizing the tooltip with ChartDataPoint itemsSource.


We have provided a sample for customizing the tooltip in our Xamarin forms sample browser. Please find the sample from the below location.




Tooltip customization has been achieved by using CustomRenderer for Andriod, WinRT and WinPhone. For iOS, instead of CustomRenderer we have used CustomDelegate.

Please let us know if you need further assistance on this.

Thank you so much!! 

Works perfect, i see the tooltip disappears after 3-4 seconds, how can i change this time, or better don't hide it until clicked in another one
