基于asp.net的图标控件chart_.NET_编程开发_程序员俱乐部

前段时间，项目中开发用到柱状图，饼图，由于vs上没有这边好的控件，在网上搜索咯下，发现chart控件的评价还是相当高的，先说下安装步骤，首先得安装.net framework 3.5sp1,对应vs2008安装MSChart_VisualStudioAddOn.exe，vs2010则安装MSChart.exe。安装好后打开vs软件，在数据类控件库里面就能看到chart控件了，拖过来就能用。
主要收下一些属性的意思，免得不会的又去学习一遍，浪费时间
前台：
<asp:Chart ID="chrCount" runat="server" BackColor="LightSteelBlue"
                BackGradientStyle="TopBottom" BackSecondaryColor="White" EnableTheming="False"
                EnableViewState="True" Height="303px" Width="1015px" ImageStorageMode="UseImageLocation">
                <Legends>
                <asp:Legend Alignment="Center" Docking="Left" Name="Legend1" Title="图例">
                </asp:Legend>
                </Legends>
                <Titles>
                <asp:Title Font="微软雅黑, 16pt" Name="Title1" Text="个贷中心信息录入岗完成笔数统计表">
                </asp:Title>
                </Titles>
                <Series>
                </Series>
                <ChartAreas>
                    <asp:ChartArea Name="ChartArea1">
                        <AxisX><MajorGrid Enabled="false" /></AxisX>
                        <AxisY><MajorGrid Enabled="false" /></AxisY>
                    </asp:ChartArea>
                </ChartAreas>
            </asp:Chart>
ImageStorageMode这个属性是否要将生产的图片保存到服务器。
后台：
DataSet dt = CStatsReportV3.CommitCountyByStaffid(dtDKFFRQ, nType, actid, gdzxdept, ref objDB);
            chrCount.DataSource=dt;
            ArrayList arrdc_staff = CStatsReportV3.F_OstaffnameListByActid(dtDKFFRQ, actid, nType, gdzxdept, ref objDB); //绑定数据源
            chrCount.Series.Clear(); 将柱状图实例情况
            if (arrdc_staff != null)//根据人员动态添加柱状图图例
            {
                foreach (Cdc_staff objstaff in arrdc_staff)
                {
                    chrCount.Series.Add(objstaff.m_nStaffid.ToString());
                    chrCount.Series[objstaff.m_nStaffid.ToString()].Legend = "Legend1";
                    chrCount.Series[objstaff.m_nStaffid.ToString()].LegendText = objstaff.m_szStaffname;
                    chrCount.Series[objstaff.m_nStaffid.ToString()].XValueMember = "strDate"; //X轴为日期
                    chrCount.Series[objstaff.m_nStaffid.ToString()].YValueMembers = objstaff.m_szStaffname; //Y轴为用户
                    //if (arrdc_staff.Count <= 5)
                    chrCount.Series[objstaff.m_nStaffid.ToString()].IsValueShownAsLabel = true;//是否显示柱状图没列值
                }
            }
            chrCount.ChartAreas["ChartArea1"].AxisY.Title = "笔数(单位：笔)"; //Y轴单位
            chrCount.ChartAreas["ChartArea1"].AxisY.TitleAlignment = StringAlignment.Far;//设置Y轴标题的名称所在位置位远
            chrCount.ChartAreas["ChartArea1"].AxisX.Interval = 1;
            //txtDateEnd.Text = chrCount.Series.LongCount().ToString();
            //string file = Server.MapPath(@"~/TmpFiles/2.jpeg");
            //chrCount.SaveImage(file, ChartImageFormat.Jpeg);
            //chrCount.ChartAreas["ChartArea1"].AxisX.MajorGrid.Enabled = false; //是否显示柱状图后面的方块
            //chrCount.ChartAreas["ChartArea1"].AxisY.MajorGrid.Enabled = false;
