我想从左侧移除轴黑线，并在按钮处添加蓝线作为所有图形的框架。 我搜索了所有属性并尝试更改颜色，但默认颜色仍然是

如果您想自定义图表，可以动态绘制自己的图表：

VB.net中的示例：

 Const GraphHeight As Integer = 100
    Const GraphWidth As Integer = 200
    Dim cIMG As New Bitmap(GraphWidth, GraphHeight)
    Dim G As Graphics = Graphics.FromImage(cIMG)
    Dim red As Integer = 0
    Dim pnts(4) As Point
    pnts(0) = New Point(0, GraphHeight - 0)
    pnts(1) = New Point(50, GraphHeight - 80)
    pnts(2) = New Point(100, GraphHeight - 50)
    pnts(3) = New Point(150, GraphHeight - 40)
    pnts(4) = New Point(200, GraphHeight - 20)
    G.DrawLines(Pens.Blue, pnts)
    PictureBox1.Image = cIMG

C＃中的示例：

const int GraphHeight = 100;
const int GraphWidth = 200;
Bitmap cIMG = new Bitmap(GraphWidth, GraphHeight);
Graphics G = Graphics.FromImage(cIMG);
int red = 0;
Point[] pnts = new Point[5];
pnts(0) = new Point(0, GraphHeight - 0);
pnts(1) = new Point(50, GraphHeight - 80);
pnts(2) = new Point(100, GraphHeight - 50);
pnts(3) = new Point(150, GraphHeight - 40);
pnts(4) = new Point(200, GraphHeight - 20);
G.DrawLines(Pens.Blue, pnts);
PictureBox1.Image = cIMG;

您可以使用循环绘制网格

我知道这个老帖子，但是要回答OP问题。

更改线条颜色和线条样式

Chart1.ChartAreas(0).AxisY.LineColor = Color.Blue
Chart1.ChartAreas(0).AxisY.LineDashStyle =ChartDashStyle.Dot

如果要删除刻度线，请使用此代码

Chart1.ChartAreas(0).AxisY.MajorTickMark.Enabled = False
Chart1.ChartAreas(0).AxisY.MinorTickMark.Enabled = False
