C# 调用mschart控件

由于网上有很多关于mschart安装及注册的信息，在这里我就不在累述，默认大家已经下载、安装并完成注册。
最近为了美化form界面，我接触到这款控件，在这里先撰写一下，自己这两天学习心得。vs用的是2017版
mschart是一款功能强大的绘图工具，可以根据不同的需要绘制相应的图形，基本满足了广大用户的需求。为了适应我做工程的需要，需要自己对控件绘图进行适当的修改，因此这篇文档，主要围绕这我自己的需要进行界面修改展开，此次修改的主要两个点在于：
1.给横纵坐标添加了相应的坐标箭头，自己设置箭头的大小；
2.根据需要在Y轴上绘制不等间距的Y轴线，并可以在合适的位置加入自己想要加入的字符；
3.保存图片的功能
先贴出效果图：（由于截图工具原因使得图片线条颜色发生了改变）

核心代码如下：

//清空原来数据缓存
            Chart1.Series[0].Points.Clear();

            //定义图表大小尺寸
            Chart1.Width = Panel1.Width + 580;
            Chart1.Height = Panel1.Height;
            
            //添加图表标题、字体、字号
            //Title title = new Title();//添加图表标题
            //title = chart1.Titles.Add("CreatByQihanWang");
            //title.Font = new Font("宋体", 20);//字体、字号
            //title.Alignment = ContentAlignment.TopCenter;//显示位置

            //chart1.Titles.
            //定义X轴、Y轴数据
            double[] Ydata = { 2, 3, 5, 99 };
            DateTime[] Xdate = new DateTime[] { DateTime.Parse("05:13:20"), DateTime.Parse("07:00"), DateTime.Parse("08:10"), DateTime.Parse("09:20") };
            //string[,] ab = new string[1, 2];
            //ab[0, 0] = "05:30:20";ab[0, 1] = "05:30:40";
            //for (int i = 0; i < ab.Length; i++)
            //{
            //    DateTime[] Xdata = new DateTime[] { DateTime.Parse(ab[0, i]) };//可以通过读取数据库数据的形式导入时间数据
            //}

保存图片功能代码如下：

//保存MSchart图
        string fileName ="1";
        private void 保存SToolStripMenuItem_Click(object sender, EventArgs e)
        {
            string saveFileName = "";
            SaveFileDialog saveDialog = new SaveFileDialog
            {
                FileName = fileName//saveDialog.FileName//fileName
            };
            saveFileName = saveDialog.FileName;

            saveDialog.Filter = "Bitmap (*.bmp)|*.bmp|JPEG (*.jpg)|*.jpg|EMF (*.emf)|*.emf|PNG (*.png)|*.png|SVG (*.svg)|*.svg|GIF (*.gif)|*.gif|TIFF (*.tif)|*.tif";
            saveDialog.FilterIndex = 2;
            saveDialog.RestoreDirectory = true;

            // Set image file format
            if (saveDialog.ShowDialog() == DialogResult.OK)
            {
                ChartImageFormat format = ChartImageFormat.Bmp;

                if (saveDialog.FileName.EndsWith("bmp"))
                {
                    format = ChartImageFormat.Bmp;
                }
                else if (saveDialog.FileName.EndsWith("jpg"))
                {
                    format = ChartImageFormat.Jpeg;
                }
                else if (saveDialog.FileName.EndsWith("emf"))
                {
                    format = ChartImageFormat.Emf;
                }
                else if (saveDialog.FileName.EndsWith("gif"))
                {
                    format = ChartImageFormat.Gif;
                }
                else if (saveDialog.FileName.EndsWith("png"))
                {
                    format = ChartImageFormat.Png;
                }
                else if (saveDialog.FileName.EndsWith("tif"))
                {
                    format = ChartImageFormat.Tiff;
                }

                // Save image
                Chart1.SaveImage(saveDialog.FileName, format);
            }
