主要记录下如何在Xamarin中使用Syncfusion组件

一、在官网注册一个使用账号 https://www.syncfusion.com

二、查看Syncfusion版本，Syncfusion分为社区免费版和付费版，付费版可以免费试用30天，官网有详细说明

社区免费版需要满足以下条件：年收入低于100万美元的公司和个人以及5个以下（包含5个）的开发人员。

然后用LinkedIn或者Xing登录，就可以获取社区免费版秘钥

三、30天试用期可以分为两种，一种是完整的安装评估，一种是通过nuget安装程序集， https://www.syncfusion.com/downloads/xamarin/confirm

四、查看官方文档，了解nuget安装程序集详细操作步骤 https://help.syncfusion.com/xamarin/licensing

五、下面详细介绍如何在Xamarin中添加一个图形报表

1、获取试用版本密钥 https://help.syncfusion.com/xamarin/nuget-packages

登录官网之后，通过地址 https://www.syncfusion.com/account/manage-trials/downloads 可以获取许可证密钥

注意选择对应的版本，然后保存生成的密钥

2、在Xamrin forms 程序启动的时候加载密钥

在nuget中引用Syncfusion.Licensing程序集，然后再App.xaml.cs文件中加入如下代码：

public App()
{
    //Register Syncfusion license
    Syncfusion.Licensing.SyncfusionLicenseProvider.RegisterLicense("YOUR LICENSE KEY");
    
    InitializeComponent();
    
    MainPage = new App1.MainPage();
}

3、引用图表控件，创建图表页面

在nuget中引用Syncfusion.Xamarin.SfChart程序集，然后就可以使用图表控件了

添加一个示例数据视图 CategoryAxisViewModel

using System.Collections.ObjectModel;
using Xamarin.Forms;

namespace SampleBrowser.SfChart
{
    public class CategoryAxisViewModel
    {
        public ObservableCollection<ChartDataModel> CategoryData { get; set; }

        public CategoryAxisViewModel()
        {
            CategoryData = new ObservableCollection<ChartDataModel>
            {
                new ChartDataModel("South Korea", 39),
                new ChartDataModel("India", 20),
                new ChartDataModel("South Africa", 61),
                new ChartDataModel("China", 65),
                new ChartDataModel("France", 45),
                new ChartDataModel("Saudi Arabia", 10),
                new ChartDataModel("Japan", 16),
                new ChartDataModel("Mexico", 31)
            };
        }
    }
}

添加一个图形报表页面
