Release Notes 4th January 2018
TeeChart for Xamarin.Forms version 2018
Build 4.1.2018.01040
Compiled with Xamarin.Forms 2.4.0.91020
===========================================

Bug fixes and New Features
--------------------------

1) Now it's easier to integrate a Chart into your APP, as the custom renders and ChartView class is already
integrated into the TeeChart NET
for Xamarin.Forms assemblies. This means you do not have to add extra files to your new
projects in order to use the Chart component.

Here the steps to add a Chart component into your APP :

- Create a Xamarin.Forms project.
- Add the TeeChart.PCL.dll assembly as reference to the PCL project.
- Add the TeeChart.PCL.dll and TeeChart.PCL.Android.dll assemblies to the PCL Android project.
- Add the TeeChart.PCL.dll and TeeChart.PCL.iOS.Unified.dll assemblies to the PCL iOS project.
- Add the TeeChart.PCL.dll and TeeChart.PCL.UWP46.dll assemblies to the PCL UWP project.
- Now you've two options :
1) Add the Chart component throught xaml code, at the xaml page. Code example :

xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:local="clr-namespace:ChartViewIntegrated"
xmlns:charting="clr-namespace:Steema.TeeChart;assembly=TeeChart.PCL"
x:Class="ChartViewIntegrated.MainPage">

------ Create TeeChart ChartView by using xaml code -----





2) Add the Chart component via CSharp code, at the .cs code class. Code example :
/* Create ChartView by code at ContentPage */
ChartView BarChart = new ChartView();
BarChart.WidthRequest = 300;
BarChart.HeightRequest = 300;
Content = new StackLayout
{
Children =
{
BarChart
},
VerticalOptions = LayoutOptions.CenterAndExpand,
HorizontalOptions = LayoutOptions.CenterAndExpand,
};

Then you only have to start configuring the Chart via cs code, i.e :
BarChart.Chart.Series.Add(new Bar());
BarChart.Chart.Series[0].FillSampleValues(3);
BarChart.Chart.Panel.Gradient.Visible = false;
BarChart.Chart.Panel.Color = Color.Aquamarine;
BarChart.Chart.Invalidate();

- IMPORTANT! : Due to the way that Xamarin.Forms iOS works, it only looks at loaded assemblies,
meaning that as TeeChart uses a custom ChartViewRenderer (now intregrated into the iOS assembly),
in order that the renderer work, we'll need to add the following line of code just before
Xamarin.Forms.Init is called (normally in the AppDelegate.cs file). :
Steema.TeeChart.TChart.Init();
Remember, this is only required for the Xamarin.Forms iOS project.
2) "System.NotImplementedException: The method or operation is not implemented."
Error. Fixed.
