C#怎么实现图表生成？用LiveCharts和OxyPlot绘制柱状图折线图饼图的方法

在C#项目里做数据可视化，LiveCharts和OxyPlot是两种主流选择。LiveCharts上手快，OxyPlot可控性强。下面分别用它们实现柱状图、折线图和饼图。

一、环境准备

使用NuGet安装对应包：

• LiveCharts：安装 LiveCharts.Wpf
• OxyPlot：安装 OxyPlot.Wpf

二、用LiveCharts绘制三种图表

1. 柱状图

在WPF中引用命名空间后，可用如下代码生成柱状图：

using LiveCharts;
using LiveCharts.Wpf;

// 创建柱状系列
var barSeries = new ColumnSeries
{
    Title = "销量",
    Values = new ChartValues<double> { 12, 19, 8, 15 }
};

var barChart = new CartesianChart
{
    Series = new SeriesCollection { barSeries },
    AxisX = new AxesCollection { new Axis { Title = "月份", Labels = new[] { "1月", "2月", "3月", "4月" } } },
    AxisY = new AxesCollection { new Axis { Title = "数值" } }
};

2. 折线图

折线图只需把系列换成 LineSeries：

using LiveCharts;
using LiveCharts.Wpf;

var lineSeries = new LineSeries
{
    Title = "温度",
    Values = new ChartValues<double> { 22.1, 24.3, 21.8, 26.0 }
};

var lineChart = new CartesianChart
{
    Series = new SeriesCollection { lineSeries },
    AxisX = new AxesCollection { new Axis { Labels = new[] { "周一", "周二", "周三", "周四" } } }
};

3. 饼图

using LiveCharts;
using LiveCharts.Wpf;

var pieChart = new PieChart
{
    Series = new SeriesCollection
    {
        new PieSeries { Title = "A", Values = new ChartValues<double> { 40 }, DataLabels = true },
        new PieSeries { Title = "B", Values = new ChartValues<double> { 60 }, DataLabels = true }
    }
};

三、用OxyPlot绘制三种图表

1. 柱状图

using OxyPlot;
using OxyPlot.Series;
using OxyPlot.Axes;

var barModel = new PlotModel { Title = "销量柱状图" };
barModel.Axes.Add(new CategoryAxis { ItemsSource = new[] { "1月", "2月", "3月" } });
barModel.Axes.Add(new LinearAxis { Title = "数值" });
barModel.Series.Add(new ColumnSeries
{
    ItemsSource = new[] { 10.0, 20.0, 15.0 }
});

2. 折线图

using OxyPlot;
using OxyPlot.Series;

var lineModel = new PlotModel { Title = "温度折线图" };
lineModel.Series.Add(new LineSeries
{
    Points = new[]
    {
        new DataPoint(0, 22.1),
        new DataPoint(1, 24.3),
        new DataPoint(2, 21.8)
    }
});

3. 饼图

using OxyPlot;
using OxyPlot.Series;

var pieModel = new PlotModel { Title = "占比" };
pieModel.Series.Add(new PieSeries
{
    Slices = new[]
    {
        new PieSlice("A", 40) { IsExploded = true },
        new PieSlice("B", 60)
    }
});

四、如何选择

如果项目追求快速集成、界面现代，选LiveCharts；如果需要导出矢量图、深度定制样式，OxyPlot更合适。两者都支持数据绑定，实际开发中按团队习惯选用即可。
