如何根据 int 值构建饼图

Question

我有一些 int 变量，我需要以 visual studio 形式基于它们创建一个饼图。我如何 link 将它们组合在一起，因为我似乎只能找到如何将其 link 到数据库，这对我来说太酷了。

Answer 1

这是一个代码示例，您可以如何创建饼图。希望对您有所帮助：

private void DrawPieChart(int value1, int value2, int value3, int value4, int value5)
{
    //reset your chart series and legends
    chart1.Series.Clear();
    chart1.Legends.Clear();

    //Add a new Legend(if needed) and do some formating
    chart1.Legends.Add("MyLegend");
    chart1.Legends[0].LegendStyle = LegendStyle.Table;
    chart1.Legends[0].Docking = Docking.Bottom;
    chart1.Legends[0].Alignment = StringAlignment.Center;
    chart1.Legends[0].Title = "MyTitle";
    chart1.Legends[0].BorderColor = Color.Black;

    //Add a new chart-series
    string seriesname = "MySeriesName";
    chart1.Series.Add(seriesname);
    //set the chart-type to "Pie"
    chart1.Series[seriesname].ChartType = SeriesChartType.Pie;

    //Add some datapoints so the series. in this case you can pass the values to this method
    chart1.Series[seriesname].Points.AddXY("MyPointName", value1);
    chart1.Series[seriesname].Points.AddXY("MyPointName1", value2);
    chart1.Series[seriesname].Points.AddXY("MyPointName2", value3);
    chart1.Series[seriesname].Points.AddXY("MyPointName3", value4);
    chart1.Series[seriesname].Points.AddXY("MyPointName4", value5);
}
