用的Chart控件，页面端代码如下

<asp:Chart ID="Chart2" runat="server" Width="850px" ImageStorageMode="UseImageLocation"

                    ImageType="Jpeg">

                    <Series>

                        <asp:Series ChartArea="ChartArea1" Name="Series2" XValueType="Double" BackImageAlignment="Center"

                            BackImageTransparentColor="Transparent" BackSecondaryColor="White" Palette="Pastel"

                            Label="#VAL" ChartType="Bar" Font="Microsoft Sans Serif, 10pt">

                        </asp:Series>

                    </Series>

                    <Titles>

                        <asp:Title Name="title" ForeColor="#333399" Font="微软雅黑, 12pt" Text="科室满意率排名%">

                        </asp:Title>

                    </Titles>

                    <ChartAreas>

                        <asp:ChartArea Name="ChartArea1" BackColor="Transparent" BorderDashStyle="Solid"

                            BorderColor="Gainsboro" IsSameFontSizeForAllAxes="True">

                            <AxisX IsLabelAutoFit="False" LabelAutoFitMaxFontSize="14" LabelAutoFitMinFontSize="12">

                                <LabelStyle Font="Microsoft Sans Serif, 12pt, style=Bold" />

                            </AxisX>

                            <Position Height="100" Width="100" />

                            <InnerPlotPosition Height="85" Width="75" X="25" Y="10" />

                            <Area3DStyle Enable3D="True" IsRightAngleAxes="False" Perspective="10" Inclination="0"

                                Rotation="2" />

                        </asp:ChartArea>

                    </ChartAreas>

                </asp:Chart>

赋值代码如下：

 DataSet ds = sftzbll.GetNewZDYTJ(dt1, dt2, 2);

                DataTable dt = ds.Tables[0];

                if (dt != null)

                {

                    DataRow[] dwlistmyld = dt.Select();

                    Chart2.Height = 30 * dwlistmyld.Length;

                    for (int i = 0; i < dwlistmyld.Length; i++)

                    {

                        if (dwlistmyld[i]["KS"].ToString() != "" && dwlistmyld[i]["MYD"].ToString() != "")

                        {

                            int p = Chart2.Series["Series2"].Points.AddXY(i, Convert.ToDouble(dwlistmyld[i]["MYD"].ToString().Replace("%", "")));

                            Chart2.Series["Series2"].Points[p].AxisLabel = dwlistmyld[i]["KS"].ToString();



                        }

                    }

                }
