使用说明
在工具箱-数据分组中我们就可以看到chart控件，使用时拖拽到界面即可。可以通过属性面板设置其样式，也可以通过代码来调整样式。设置的属性可参照：https://www.cnblogs.com/arxive/p/5861960.html
下面展示下自己做技术测试的图片：
总结了部分设置chart样式功能的通用类：

使用示例(开头四个图表）
chart1.Series.Clear();
ChartHelper.AddSeries(chart1, "柱状图", SeriesChartType.Column, Color.Lime, Color.Red, true);
ChartHelper.AddSeries(chart1, "曲线图", SeriesChartType.Spline, Color.Red, Color.Red);
ChartHelper.SetTitle(chart1, "柱状图与曲线图", new Font("微软雅黑", 12), Docking.Bottom, Color.White);
ChartHelper.SetStyle(chart1, Color.Transparent, Color.White);
ChartHelper.SetLegend(chart1, Docking.Top, StringAlignment.Center, Color.Transparent, Color.White);
ChartHelper.SetXY(chart1, "序号", "数值", StringAlignment.Far, Color.White, Color.White, AxisArrowStyle.SharpTriangle, 1, 2);
ChartHelper.SetMajorGrid(chart1, Color.Gray, 20, 2);
chart2.Series.Clear();
ChartHelper.AddSeries(chart2, "饼状图", SeriesChartType.Pie, Color.Lime, Color.Red, true);
ChartHelper.SetStyle(chart2, Color.Transparent, Color.White);
ChartHelper.SetLegend(chart2, Docking.Top, StringAlignment.Center, Color.Transparent, Color.White);
chart3.Series.Clear();
ChartHelper.AddSeries(chart3, "曲线图", SeriesChartType.SplineRange, Color.FromArgb(100,46, 199, 201), Color.Red, true);
ChartHelper.SetTitle(chart3, "曲线图", new Font("微软雅黑", 12), Docking.Bottom, Color.FromArgb(46, 199, 201));
ChartHelper.SetStyle(chart3, Color.Transparent, Color.White);
ChartHelper.SetLegend(chart3, Docking.Top, StringAlignment.Center, Color.Transparent, Color.White);
ChartHelper.SetXY(chart3, "序号", "数值", StringAlignment.Far, Color.White, Color.White, AxisArrowStyle.SharpTriangle, 1, 2);
ChartHelper.SetMajorGrid(chart3, Color.Gray, 20, 2);
chart4.Series.Clear();
ChartHelper.AddSeries(chart4, "饼状图", SeriesChartType.Funnel, Color.Lime, Color.Red, true);
ChartHelper.SetStyle(chart4, Color.Transparent, Color.White);
ChartHelper.SetLegend(chart4, Docking.Top, StringAlignment.Center, Color.Transparent, Color.White);
RefreshData();
绑定数据部分代码如下：
public void RefreshData()
{
List<int> x1 = new List<int>() { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 };
List<int> y1 = new List<int>();
Random ra = new Random();
y1 = new List<int>() {
ra.Next(1, 10),
ra.Next(1, 10),
ra.Next(1, 10),
ra.Next(1, 10),
ra.Next(1, 10),
ra.Next(1, 10),
ra.Next(1, 10),
ra.Next(1, 10),
ra.Next(1, 10),
ra.Next(1, 10),
ra.Next(1, 10),
ra.Next(1, 10)
};
RefreshChart(x1, y1, "chart1");
RefreshChart(x1, y1, "chart2");
RefreshChart(x1, y1, "chart3");
RefreshChart(x1, y1, "chart4");
}
public delegate void RefreshChartDelegate(List<int> x, List<int> y, string type);
public void RefreshChart(List<int> x, List<int> y, string type)
{
if (type == "chart1")
{
if (this.chart1.InvokeRequired)
{
RefreshChartDelegate stcb = new RefreshChartDelegate(RefreshChart);
this.Invoke(stcb, new object[] { x, y, type });
}
else
{
chart1.Series[0].Points.DataBindXY(x, y);
chart1.Series[1].Points.DataBindXY(x, y);
}
}
else if (type == "chart2")
{
if (this.chart2.InvokeRequired)
{
RefreshChartDelegate stcb = new RefreshChartDelegate(RefreshChart);
this.Invoke(stcb, new object[] { x, y, type });
}
else
{
chart2.Series[0].Points.DataBindXY(x, y);
List<Color> colors = new List<Color>() {
Color.Red,
Color.DarkRed,
Color.IndianRed,
Color.MediumVioletRed,
Color.OrangeRed,
Color.PaleVioletRed,
Color.Purple,
Color.DarkOrange,
Color.Maroon,
Color.LightCoral,
Color.LightPink,
Color.Magenta
};
DataPointCollection points = chart2.Series[0].Points;
for (int i = 0; i < points.Count; i++)
{
points[i].Color = colors[i];
}
}
}
else if (type == "chart3")
{
if (this.chart3.InvokeRequired)
{
RefreshChartDelegate stcb = new RefreshChartDelegate(RefreshChart);
this.Invoke(stcb, new object[] { x, y, type });
}
else
{
chart3.Series[0].Points.DataBindXY(x, y);
}
}
else if (type == "chart4")
{
if (this.chart4.InvokeRequired)
{
RefreshChartDelegate stcb = new RefreshChartDelegate(RefreshChart);
this.Invoke(stcb, new object[] { x, y, type });
}
else
{
chart4.Series[0].Points.DataBindXY(x, y);
List<Color> colors = new List<Color>() {
Color.Red,
Color.DarkRed,
Color.IndianRed,
Color.MediumVioletRed,
Color.OrangeRed,
Color.PaleVioletRed,
Color.Purple,
Color.DarkOrange,
Color.Maroon,
Color.LightCoral,
Color.LightPink,
Color.Magenta
};
DataPointCollection points = chart4.Series[0].Points;
for (int i = 0; i < points.Count; i++)
{
points[i].Color = colors[i];
}
}
}
}
为了让图表展现动画效果，添加了一个定时器，用来实时改变数据，这样就可以看到动起来的图表了。定时器代码如下：
private void Timer1_Tick(object sender, EventArgs e)
{
new Thread(new ThreadStart(RefreshData)).Start();
}

以上只是使用chart控件的几个简单示例，而chart控件的功能远远不止这些。为了更方便地了解和使用其他功能，特提供了一些资料，其中包括图表的属性说明文档、各类图表的样式和对应的代码、以及程序示例等，下载地址如下：
