C#语言Devdevexpress控件chart在C/S框架中的使用

声明、数据库连接机制框架已经写好。框架模式是MVC模式。就以我的from测试。我的做法是在查询页面创建一个按钮，然后在这个按钮上绑定一个点击事件。点击查询按钮把查询条件传到需要显示图例的页面。查询页面→显示图例页面

new一下需要传值的页面例如我这样

private void simpleButton2_Click(object sender, EventArgs e)

{
FrmTyp p = new FrmTyp(ConvertEx.ToSqlMinDate(txt_CREATIONDATE1.DateTime),
ConvertEx.ToSqlMinDate(txt_CREATIONDATE2.DateTime),
textEdit11.Text,
EXAMINOR1,
txt_CCNO.Text,
textEdit1.Text,
DRAW_CD.Text,
REPORTID.Text,
PRODUCT_TYP.Text);
p.Show();
}

1、创建一个from窗口，添加控件chart。

2、from全部代码和页面

using CSFramework.Common;
using CSFramework3.Server.DataAccess;
using DevExpress.XtraCharts;
using System;
using System.Data;
using System.Drawing;
using System.Windows.Forms;

namespace CSFramework3.AccountModule
{
public partial class FrmTyp : CSFramework.Library.frmBase//CSFramework.Library.frmBase 继承了皮肤，如果没有皮肤就不用继承。
{
DateTime CREATIONDATE1, CREATIONDATE2;
string EXAMINOR1, textEdit11, CCNO, textEdit1, DRAW_CD, REPORTID , PRODUCT_TYP;//定义了从另一个页面传过来的参数，就是查询条件。如果没有查询条件就删除
public FrmTyp(DateTime CREATIONDATE1, DateTime CREATIONDATE2, string textEdit11, string EXAMINOR1,
string CCNO, string textEdit1, string DRAW_CD, string REPORTID, string PRODUCT_TYP)
{
InitializeComponent();
this.CREATIONDATE1 = CREATIONDATE1;
this.CREATIONDATE2 = CREATIONDATE2;
this.textEdit11 = textEdit11;
this.EXAMINOR1 = EXAMINOR1;
this.CCNO = CCNO;
this.textEdit1 = textEdit1;
this.DRAW_CD = DRAW_CD;
this.REPORTID = REPORTID;
this.PRODUCT_TYP = PRODUCT_TYP;
}

private void FrmTyp_Load(object sender, EventArgs e)
{
//设置图表标题
ChartTitle ct = new ChartTitle();
ct.Text = "统计图";
ct.TextColor = Color.OrangeRed;//颜色
ct.Font = new Font("Tahoma", 14);//字体
ct.Dock = ChartTitleDockStyle.Top;//停靠在上方
ct.Alignment = StringAlignment.Center;//居中显示
this.chartControl1.Titles.Add(ct);
}

break;
}
//设置Series样式
mySeries.ArgumentScaleType = ScaleType.Qualitative;//定性的

//绑定数据源

PRODUCT_TYP = "齿轮泵";

//QueryTyp是数据访问层的一个方法，就是指向SQL语句。你怎么查询数据库的这里就怎么指向查询语句。
