Cycle through the .dataPoints collection off the chart and find the object

        public override void ItemTapped (IGPieChartView pieChartView, IGPieSliceInfo item, System.Drawing.PointF point)
        {
            IGCategoryPoint dataPoint = (IGCategoryPoint)item.Item;

            for (int i = 0; i <    pieChartView.DataPoints.Count; i++) {

                IGCategoryPoint tempObject = pieChartView.DataPoints.GetItem<IGCategoryPoint>(i);
                if (dataPoint == tempObject) 
                {
                    // now i is your index;
                    int xx = 0;
                    xx++;
                }
            }
        }

  My pie chart always contains to slides on is ontime and another one is latetime.  When ever user click on ontime slice then i want to get that slice index value. Based on that index value i want show data. How can i get the slice index value when ever user tapped on slice. I want code snippet in C#.net

   public override void ItemTapped(IGPieChartView pieChartView, IGPieSliceInfo item, System.Drawing.PointF point)
            {

}

using this method possible to get slice index.

That would translate to the GetPointAt method off the datasource helper.  

It would look something like this:

public override IGDataPoint GetPointAt (IGPieChartView pieChartView, int index)
        {
            double myValue = ((NSNumber)_data [index]).DoubleValue;

            NSString newString = "someNewString";

            return new IGCategoryPoint (myValue, newString);
        }

I want this one in c#

-(IGDataPoint *)pieChartView:(IGPieChartView *)pieChartView pointAtIndex:(int)index
{
   double value = [(NSNumber*)_data[index] doubleValue];

   //any text set here will be displayed in the slices and the legend.
   NSString *label = [NSString stringWithFormat:@"Item %d", index];
   return [[IGCategoryPoint alloc]initWithValue:value andLabel:label];
}

How can i get  IGPieSliceInfo index value in Xamarin c#.

For example I have a pie chart with two slice. One is Ontime and Lateness. I didn't show label on the IGpiechartview. So how can i get the particular slice is click. I am using following code. in this override method i want to get information about clicked slice.

If user click on OnTime slice then i want to get that OnTime slice information. In the following code i am getting value and label but i didn't show the label on slice. There is a way to Hidden the label value on slice.

Thanks,
