1、新建Chart
2、把名字位置改到上方
3、操作
chartRes.ChartAreas[0].AxisX.MajorGrid.LineDashStyle = ChartDashStyle.NotSet; //设置网格类型为虚线
chartRes.ChartAreas[0].AxisY.MajorGrid.LineDashStyle = ChartDashStyle.Dot; //设置网格类型为虚线
chartRes.ChartAreas[0].AxisX.Interval = 10; //X轴数值间隔
chartRes.ChartAreas[0].AxisX.LabelStyle.IsStaggered = true;
chartRes.ChartAreas[0].AxisX.LabelStyle.Angle = -30; //X轴数据的角度
chartRes.Series[0].ChartType = SeriesChartType.Line; //图表类型为曲线
chartRes.ChartAreas[0].AxisX.TextOrientation = TextOrientation.Horizontal; //文本方向为水平
chartRes.Series[0].Points.DataBindXY(x, y); // 绑定数据
chartRes.Series[0].Label = "(#VALX℃：#VALMpa)"; // 设置显示X Y的值
chartRes.ChartAreas[0].AxisY.Title = "压力（MPa）";
chartRes.ChartAreas[0].AxisX.Title = "温度（℃）";
chartRes.Series[0].LegendText = "温度-压力曲线";
string fullFileName = @"../../Docs/111.png";
chartRes.SaveImage(fullFileName, System.Windows.Forms.DataVisualization.Charting.ChartImageFormat.Png); //保存曲线图
fullFileName= Path.GetFullPath(fullFileName.ToString()); //根据相对路径获取绝对路径
