我有一些整型变量,在Visual Studio表单中需要通过它们创建一个饼图。我该如何将它们链接在一起?我似乎只能找到如何将其链接到数据库,这对我来说太复杂了。
我有一些整型变量,在Visual Studio表单中需要通过它们创建一个饼图。我该如何将它们链接在一起?我似乎只能找到如何将其链接到数据库,这对我来说太复杂了。
这是一个代码示例,展示如何创建饼图。希望这能帮到你:
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);
}
chart1.SaveImage("sample.png", System.Drawing.Imaging.ImageFormat.Png)
。但是 sample.png 文件只是一个空白的白屏,有人能否请指正一下原因? - zeal
using System.Windows.Forms.DataVisualization.Charting;
以便更轻松地访问属性!您只需将整数作为系列.points.add调用中的值即可。 - TaW
