如何在折线系列图表 X 轴 Windows Phone 8.1 中绑定日期

本文关键字：Phone Windows 日期 绑定 折线 系列 | 更新日期: 2023-09-27 18:32:13

在折线系列图中，我想通过将日期绑定在 x 轴上来显示日期，在 y 轴上索引从 90 开始我正在使用 WCF 方法来访问日期

.xaml 代码

<Charting:Chart Name="MyChart" Title="" Margin="11,153,-2,39">  
<Charting:LineSeries Margin="0" IndependentValuePath="Item1"   
 DependentValuePath="Item2" IsSelectionEnabled="True" Title="Blood Glucose" 
 Foreground="Black" ItemsSource="{Binding Measurement}" />
</Charting:Chart>

.xaml.cs

        string result = await WCFRESTServiceCall("GET", "getbg1?Email=" + 
        emailtxtbox.Text + "");
        result = result.Replace("{'"getbg1Result'":", "");
        result = result.Replace("]}", "]");
        List<BG> data = JsonConvert.DeserializeObject<List<BG>>(result);
        int item1 = 0;
        int item2 = 1;
        int item3 = 2;
        string a1 = "";
        string b2 = "";
        string c3 = "";
        foreach (BG b in data)
        {
             item1 = b.Measurement[0];
             item2 = b.Measurement[1];
             item3 = b.Measurement[2];
                a1 = b.Date_[0].ToString();
                b2 = b.Date_[1].ToString();
                c3 = b.Date_[2].ToString();
        }
        List<Tuple<string, int>> myList = new List<Tuple<string, int>>()
        {
            new Tuple<string, int>(a1, item1),
            new Tuple<string, int>(b2, item2),
            new Tuple<string, int>(c3, item3)                
    };
        (MyChart.Series[0] as LineSeries).ItemsSource = myList;
       }

我已经通过执行这些代码行解决了我的问题

    protected async override void OnNavigatedTo(NavigationEventArgs e)
    {
        string result = await WCFRESTServiceCall("GET", "getbg1?Email=" +   
                                                    emailtxtbox.Text + "");
        result = result.Replace("{'"getbg1Result'":", "");
        result = result.Replace("]}", "]");
        List<BG> data = JsonConvert.DeserializeObject<List<BG>>(result);
        int item1 = 0;
        int item2 = 1;
        int item3 = 2;
        int item4 = 0;
        item1 =int.Parse( data[0].Measurement);
        item2 = int.Parse(data[1].Measurement);
        item3 = int.Parse(data[2].Measurement);

        List<Tuple<string, int>> myList = new List<Tuple<string, int>>()
        {

            new Tuple<string, int>(data[0].Date_, item1),
            new Tuple<string, int>(data[1].Date_, item2),
            new Tuple<string, int>(data[2].Date_, item3),            
        };
        (MyChart.Series[0] as LineSeries).ItemsSource = myList;

    }
