I have a DateTimeAxis as the PrimaryAxis  and a NumbericAxis as the SecondaryAxis.  How do I display the DateTime and Values in the tooltip ?  
Ii have the code below but it is not displaying the Date and Time.   Thank you.

chartTop.Behaviors.Add(new ChartTooltipBehavior() { LabelFormat = "dd/MM/yy hh:mm" });

Hi Albert, 
Thanks for using Syncfusion products. 
You can achieve this requirement by overriding the GetView method in ChartTooltipBehavior class. Please refer the following code snippet for more details. 
Code Snippet: 
   protected override View GetView(TooltipView tooltipView) 
            LinearLayout rootLayout = new LinearLayout(Chart.Context); 
            LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MatchParent, 
            rootLayout.Orientation = Orientation.Vertical; 
            rootLayout.LayoutParameters = layoutParams; 
            TextView xLabel = new TextView(Chart.Context); 
            string date = (tooltipView.ChartDataPoint as DataModel).XValue.ToString(); 
            var doubleToDate = DateTime.FromOADate(Convert.ToDouble(date)); 
            var formattedDate = doubleToDate.ToString("dd/MM/yy hh:mm"); 
            xLabel.Text = "Date:" + formattedDate.ToString(); 
            xLabel.TextSize = 15; 
            TextView yLabel = new TextView(Chart.Context); 
            yLabel.Text = "YValue: " + (tooltipView.ChartDataPoint as DataModel).YValue.ToString(); 
            yLabel.TextSize = 15; 
            return tooltipView; 
We have prepared the sample based on your requirement. Please download the sample from following location.
