Winform Chart控件怎么设置格网为虚线，就像matlab中一样

Question

我试了下面这段代码，没有用。

 Chart1.ChartAreas[3].AxisX.MajorGrid.LineDashStyle = ChartDashStyle.Dash

Answer 1

試試在ChartAreas = 0 設，看看有沒有效果

chart1.ChartAreas[0].AxisX.MajorGrid.LineDashStyle = System.Windows.Forms.DataVisualization.Charting.ChartDashStyle.DashDotDot;

Answer 2

不行，设置了格网的线形之后格网的线没有变虚线，但是变粗了。

Answer 3

Hi，

你可以试试以下的代码(除了这个两条语句没做任何修改)：

chart1.ChartAreas[0].AxisX.MajorGrid.LineDashStyle = System.Windows.Forms.DataVisualization.Charting.ChartDashStyle.DashDotDot;
chart1.ChartAreas[0].AxisY.MajorGrid.LineDashStyle = System.Windows.Forms.DataVisualization.Charting.ChartDashStyle.DashDotDot;

参考链接：

ChartDashStyle Enumeration

如果无效的话你检查下你的代码，可能你在其他地方修改了这个地方的网格样式。

都有试过，但是我发现我的网格线条没有变成虚线，而是变粗了，很奇怪，下面是我的代码。

Chart1.ChartAreas[0].AxisX.MajorGrid.LineDashStyle = ChartDashStyle.DashDotDot;
Chart1.ChartAreas[0].AxisY.MajorGrid.LineDashStyle = ChartDashStyle.Dash;
Chart1.ChartAreas[0].AxisX.MajorTickMark.Enabled = false;
Chart1.ChartAreas[0].AxisY.MajorTickMark.Enabled = false;
Chart1.ChartAreas[0].AxisX.IntervalAutoMode = IntervalAutoMode.VariableCount;
Chart1.ChartAreas[0].AxisX.MajorGrid.Interval = 3600;
Chart1.ChartAreas[0].AxisX.Interval = 3600;
Chart1.ChartAreas[0].AxisX.Maximum = 3600 * ((int)m / 3600 + 1);
Chart1.ChartAreas[0].AxisX.Minimum = 0;
Chart1.Series.Add("Latitude");
Chart1.ChartAreas[0].AxisX.Title = "Epoch[h]";
Chart1.ChartAreas[0].AxisX.TitleFont = new Font("TimesNewRoman", 10);
Chart1.ChartAreas[0].Position.Width = 45;
Chart1.ChartAreas[0].Position.Height = 30;
Chart1.Series[0].ChartType = SeriesChartType.Line;
Chart1.Series[0].Points.DataBindXY(time,rms_x);  
Chart1.ChartAreas[0].AxisY.Title = "Latitude[m]";
Chart1.ChartAreas[0].AxisY.TitleFont = new Font("TimesNewRoman", 10);
Chart1.ChartAreas[0].AxisX.LabelStyle.IsStaggered = false;

//Chart1.ChartAreas[0].AxisX.LabelStyle.Interval = 1;
Chart1.ChartAreas[0].Name = "Latitude";
Chart1.ChartAreas[0].Position.X = 0;
Chart1.ChartAreas[0].Position.Y = 0;
Chart1.Series[0].ChartArea = "Latitude";

Answer 5

你好，

我把你的代码拿去测试了也没你提及的问题啊，你在属性面板那边看看是不是你在设计器里面修改了某些设置。

下面是我的测试代码（可能是chart1.ChartAreas[0].Position这个属性影响了，我试了下你原来的直接缩成一团了）：

            Random ran = new Random();


            chart1.ChartAreas[0].AxisX.MajorGrid.LineDashStyle = ChartDashStyle.DashDotDot;
            chart1.ChartAreas[0].AxisY.MajorGrid.LineDashStyle = ChartDashStyle.Dash;
            chart1.ChartAreas[0].AxisX.MajorTickMark.Enabled = false;
            chart1.ChartAreas[0].AxisY.MajorTickMark.Enabled = false;
            chart1.ChartAreas[0].AxisX.IntervalAutoMode = IntervalAutoMode.VariableCount;
           // chart1.ChartAreas[0].AxisX.MajorGrid.Interval = 3600;
            //chart1.ChartAreas[0].AxisX.Interval = 3600;
           // chart1.ChartAreas[0].AxisX.Maximum = 3600 * ((int)2 / 3600 + 1);
            //chart1.ChartAreas[0].AxisX.Minimum = 0;

            chart1.Series.Add("Latitude");
            chart1.ChartAreas[0].AxisX.Title = "Epoch[h]";
            chart1.ChartAreas[0].AxisX.TitleFont = new Font("TimesNewRoman", 10);
            chart1.ChartAreas[0].Position.Width = 99;
            chart1.ChartAreas[0].Position.Height = 99;
            chart1.Series[0].ChartType = SeriesChartType.Line;
            //chart1.Series[0].Points.DataBindXY(time, rms_x);
            chart1.ChartAreas[0].AxisY.Title = "Latitude[m]";
            chart1.ChartAreas[0].AxisY.TitleFont = new Font("TimesNewRoman", 10);
            chart1.ChartAreas[0].AxisX.LabelStyle.IsStaggered = false;

            //chart1.ChartAreas[0].AxisX.LabelStyle.Interval = 1;
            chart1.ChartAreas[0].Name = "Latitude";
            chart1.ChartAreas[0].Position.X = 0;
            chart1.ChartAreas[0].Position.Y = 0;
            chart1.Series[0].ChartArea = "Latitude";

            chart1.Series[0].Points.AddXY(ran.Next(0, 3600), ran.Next(0, 100));
            chart1.Series[0].Points.AddXY(ran.Next(0, 3600), ran.Next(0, 100));
            chart1.Series[0].Points.AddXY(ran.Next(0, 3600), ran.Next(0, 100));
            chart1.Series[0].Points.AddXY(ran.Next(0, 3600), ran.Next(0, 100));
            chart1.Series[0].Points.AddXY(ran.Next(0, 3600), ran.Next(0, 100));
            chart1.Series[0].Points.AddXY(ran.Next(0, 3600), ran.Next(0, 100));
            chart1.Series[0].Points.AddXY(ran.Next(0, 3600), ran.Next(0, 100));

如果还是没效果的话，你能否提供重现样本程序，我会测试一下。

Moonlight

Answer 6

我的数据是在0左右波动的，大概有3000条左右，属性面板我只改了Chart.Visible = false;因为我直接把图存成图片了。

Answer 7

谢谢！

我找到问题所在了，我是将Chart作为参数传递给一个对象来处理的，在对象里面设置的线形无效。
