Add grid line annotation for the datetime axes. the grid lines are not visualized on iOS.

Put several Pie charts in a StackPanel and set the WidthRequest and HeightRequest to let's say 60. You will notice that the circular pie itlsef appears much smaller than the expected 60. In Android and Windows Phone it appears as expected.

When having the following code on a button click 

private void Button_Clicked(object sender, System.EventArgs e)
{
       this.chart.Zoom = new Size();
}

The chart zoom is reset first time, but when zooming again and pressing the button, the zoom level does not reset. You have to pan the chart, then zoom reset works. 

This code resets the zoom:

private void OnResetZoomClicked(object sender, EventArgs e)
{
	this.chart.Zoom = new Size(1, 1); // This line is added as a workaround to reset the Zoom level
	this.chart.Zoom = new Size();
}

Add the ability to render points outside of the plot area when the data point value exceeds the explicitly set Min or Max values of the horizontal axis.

On Android and iOS, the line series will continue to extend off the plot area to a point that isn't rendered. Here's a screenshot, notice the line coming in from the left side of the plot area: https://www.telerik.com/clientsfiles/77e02115-6de0-4dd0-b572-5d5bc17a59b9_xamarin.jpg

On UWP, the beginning of the line series only starts on the first plot-able point. Here's a screenshot, notice the start of the line series: https://www.telerik.com/clientsfiles/d8c342e3-608b-40eb-95eb-8bd5e0dbc2e6_uwp.jpg

If you have a Chart with BarSeries and TooltipBehavior defined, the tooltip of each bar is shown only when the user taps in the area around the tip of the bar.

The expected behavior is the tooltip to be displayed when clicking anywhere on the bar.
