效果如下：左侧纵坐标表示柱形图Y轴数据，右侧纵坐标表示折线图Y轴数据
代码：
private void ButtonClickSelect()
{
string GD = textBoxGD.Text.Trim();
string XH = textBoxXH.Text.Trim();
string CJ = comboBoxCJ.Text.Trim();
string Date1 = dateTimePicker1.Value.ToString("yyyyMMdd HH:mm:ss");
string Date2 = dateTimePicker2.Value.ToString("yyyyMMdd HH:mm:ss");
DataTable dt = BLL.MES.GetNGBoLaTuP1(GD, XH, CJ, Date1, Date2);
if (dt != null && dt.Rows.Count > 0)
{
string ID_UNIQUE = BLL.Config.GetNewID();
dt.Columns.Add("BLL");
dt.Columns.Add("ID");
for (int i = 0; i < dt.Rows.Count; i++)
{
dt.Rows[i]["BLL"] = (Math.Round(decimal.Parse(dt.Rows[i]["NGQty"].ToString()) / decimal.Parse(dt.Rows[i]["TR"].ToString()), 2) * 100).ToString() + "%";
dt.Rows[i]["ID"] = ID_UNIQUE;
}
bool flag = Util.DBHelper.AddTable(dt, "NGBoLaTuTempSave");
if (flag)
{
chart1.ChartAreas["ChartArea1"].Area3DStyle.Enable3D = false;
chart1.ChartAreas["ChartArea1"].Area3DStyle.LightStyle = LightStyle.Realistic;
chart1.ChartAreas["ChartArea1"].BackColor = System.Drawing.Color.FromArgb(((System.Byte)(64)), ((System.Byte)(165)), ((System.Byte)(191)), ((System.Byte)(228)));
chart1.ChartAreas["ChartArea1"].CursorX.AutoScroll = true;
chart1.ChartAreas["ChartArea1"].AxisX.ScrollBar.Enabled = true;
chart1.ChartAreas["ChartArea1"].CursorX.IsUserEnabled = true;
chart1.ChartAreas["ChartArea1"].CursorX.IsUserSelectionEnabled = true;
chart1.ChartAreas["ChartArea1"].AxisX.ScaleView.Zoomable = true;
chart1.ChartAreas["ChartArea1"].AxisX.ScaleView.Position = 1;
chart1.ChartAreas["ChartArea1"].AxisX.ScaleView.Size = 10;
chart1.ChartAreas["ChartArea1"].AxisX.ScrollBar.ButtonColor = System.Drawing.Color.Silver;
chart1.ChartAreas["ChartArea1"].AxisX.ScrollBar.LineColor = System.Drawing.Color.Black;
chart1.ChartAreas[0].AxisX.MajorGrid.LineWidth = 0;
chart1.ChartAreas[0].AxisX.Interval = 1; //设置X轴坐标的间隔为1
chart1.ChartAreas[0].AxisX.IntervalOffset = 1; //设置X轴坐标偏移为1
chart1.ChartAreas[0].AxisX.LabelStyle.IsStaggered = true;
chart1.ChartAreas[0].BackColor = Color.White;//设置背景为白色
//chart1.ChartAreas[0].AxisX.ScrollBar.ButtonStyle = ScrollBarButtonStyles.All;//启用X轴滚动条按钮
dt = BLL.MES.GetNGBoLaTuTempSaveData(ID_UNIQUE);
if (dt != null && dt.Rows.Count > 0)
{
chart1.Series[0].Points.Clear();
chart1.Series[0].IsValueShownAsLabel = true;//显示标签
for (int m = 0; m < dt.Rows.Count; m++)
{
for (int n = 0; n < dt.Columns.Count; n++)
{
chart1.Series[0].Points.AddXY(dt.Columns[n].ColumnName, dt.Rows[m][n].ToString());
}
}
}
dt = BLL.MES.GetNGBoLaTu2TempSaveData(ID_UNIQUE);
if (dt != null && dt.Rows.Count > 0)
{
chart1.Series[1].Points.Clear();
chart1.Series[1].IsValueShownAsLabel = true;//显示标签
chart1.Series[1].MarkerStyle = MarkerStyle.Circle; //线条上的数据点标志类型
chart1.Series[1].MarkerSize = 8; //标志大小
// 宽度
chart1.Series[1].BorderWidth = 2;
// 线条颜色
chart1.Series[1].Color = Color.Red;
//数据点颜色
chart1.Series[1].MarkerColor = Color.BlueViolet;
chart1.Series[1].Label = "#VAL{P}";//设置标签文本 (在设计期通过属性窗口编辑更直观)
chart1.ChartAreas[0].AxisY2.LabelStyle.Format = "0.00%";
for (int m = 0; m < dt.Rows.Count; m++)
{
for (int n = 0; n < dt.Columns.Count; n++)
{
chart1.Series[1].Points.AddXY(dt.Columns[n].ColumnName, double.Parse(dt.Rows[m][n].ToString().Trim('%'))*0.01);
}
}
}
//查询完成之后，删除临时表数据
string sql = "";
List paras = new List();
sql = "delete NGBoLaTuTempSave where ID = @ID";
paras = new List() {
new SqlParameter("@ID",ID_UNIQUE),
};
string str = Util.DBHelper.Action(sql, paras);
str = Util.DBHelper.Action(sql, paras);
}
}
}
1、以下代码是显示横坐标滚动条
chart1.ChartAreas["ChartArea1"].Area3DStyle.Enable3D = false;
chart1.ChartAreas["ChartArea1"].Area3DStyle.LightStyle = LightStyle.Realistic;
chart1.ChartAreas["ChartArea1"].BackColor = System.Drawing.Color.FromArgb(((System.Byte)(64)), ((System.Byte)(165)), ((System.Byte)(191)), ((System.Byte)(228)));
chart1.ChartAreas["ChartArea1"].CursorX.AutoScroll = true;
chart1.ChartAreas["ChartArea1"].AxisX.ScrollBar.Enabled = true;
chart1.ChartAreas["ChartArea1"].CursorX.IsUserEnabled = true;
chart1.ChartAreas["ChartArea1"].CursorX.IsUserSelectionEnabled = true;
chart1.ChartAreas["ChartArea1"].AxisX.ScaleView.Zoomable = true;
chart1.ChartAreas["ChartArea1"].AxisX.ScaleView.Position = 1;
chart1.ChartAreas["ChartArea1"].AxisX.ScaleView.Size = 10;
chart1.ChartAreas["ChartArea1"].AxisX.ScrollBar.ButtonColor = System.Drawing.Color.Silver;
chart1.ChartAreas["ChartArea1"].AxisX.ScrollBar.LineColor = System.Drawing.Color.Black;
2、这是设置第二条折线的纵坐标以百分号形式显示
chart1.ChartAreas[0].AxisY2.LabelStyle.Format = "0.00%";
3、chart1.Series[0]表示第一条曲线，chart1.Series[1]表示第二条曲线
4、如何设置纵坐标显示在右侧，如下图
