求一C#柱状图，曲线图的源码

实现效果如下：纵列显示数据量，横列显示12个月。每个月有10个柱要显示。不知哪位高人有比较好看的图表及源码，请指教！万分感谢！！

自己随便画个就行了,

做一个好的比较费劲,网上应该有免费图表控件下载的,你去找找吧

这是个画柱状图的！
去看看吧！

谢谢 谢谢 非常有用啊
再次感谢

要是有简单的演示程序就好了！

柱状图，代码如下：
注意：请注意参数 chartTable 图形里的一些元素需要从chartTable里面取。具体请查看代码。

        //Render是图形大标题，图开小标题，图形宽度，图形长度，饼图的数据集和饼图的数据集  
        public Image Render(string title, int width, int height, DataTable chartTable)
        {
            Bitmap bm = new Bitmap(width, height);
            Graphics g = Graphics.FromImage(bm);
            g.Clear(Color.White);

            DataTable dt = chartTable;
            const int top = 30;
            const int left = 35;

            if (width < left * 2 || height < top * 2)
            {
                g.DrawString("绘图区域太小", new Font("Tahoma", 8),
                    Brushes.Blue, new PointF(0, 0));
                return bm;
            }

            //计算最高的点  
            float highPoint = 1;
            foreach (DataRow dr in dt.Rows)
            {
               if (highPoint < Convert.ToSingle(dr[0]))
                {
                    highPoint = Convert.ToSingle(dr[0]);
                }

                if (highPoint < Convert.ToSingle(dr[1]))
                {
                    highPoint = Convert.ToSingle(dr[1]);
                }
            }
            try
            {
                //画大标题  
                g.DrawString(title, new Font("Tahoma", 12), Brushes.Black, new PointF(2, 2));
                StringFormat drawFormat = new StringFormat();
                drawFormat.FormatFlags = StringFormatFlags.DirectionVertical;

                g.DrawString("[红--" + dt.Columns[0].ToString() + "]", new Font("Tahoma", 8),
                    Brushes.Red, new PointF(2, top), drawFormat);
                g.DrawString("[蓝--" + dt.Columns[1].ToString() + "]", new Font("Tahoma", 8),
                    Brushes.Blue, new PointF(17, top), drawFormat);

                //画条形图  
                float barWidth = (Convert.ToSingle(width) - left) / (dt.Rows.Count * 3 + 1);
                PointF barOrigin = new PointF(left + barWidth, 0);
                float barHeight = dt.Rows.Count;
                float topFontSize = (barWidth / highPoint.ToString().Length);
                 
                if (topFontSize > 2*top/3)
                {
                    topFontSize = 2*top/3;
                }
                if (topFontSize < 5)
                {
                    topFontSize = 5;
                }
                for (int i = 0; i < dt.Rows.Count; i++)
                {
                    //底部字体的大小
                    float bottomFontSize = (2 * barWidth / dt.Rows[i][2].ToString().Length) + 2;
                    if (bottomFontSize > 2 * top / 3)
                    {
                        bottomFontSize = 2 * top / 3;
                    }

                    barHeight = Convert.ToSingle(dt.Rows[i][0]) * (height - 2 * top) / highPoint * 1;
                    barOrigin.Y = height - barHeight - top;
                    g.FillRectangle(new SolidBrush(Color.Red), barOrigin.X, barOrigin.Y, barWidth, barHeight);
                    //柱状图底部
                    g.DrawString(dt.Rows[i][2].ToString(), new Font("Tahoma", bottomFontSize), Brushes.Black,
                        new PointF(barOrigin.X, height - top));
                    //柱状图顶部
                    g.DrawString(dt.Rows[i][0].ToString(), new Font("Tahoma", topFontSize), Brushes.Red,
                        new PointF(barOrigin.X, barOrigin.Y - 3*topFontSize/2));

                    barOrigin.X = barOrigin.X + barWidth;


                    barHeight = Convert.ToSingle(dt.Rows[i][1]) * (height - 2 * top) / highPoint * 1;
                    barOrigin.Y = height - barHeight - top;
                    g.FillRectangle(new SolidBrush(Color.Blue), barOrigin.X, barOrigin.Y, barWidth,  

barHeight);
                    //柱状图顶部
                    g.DrawString(dt.Rows[i][1].ToString(), new Font("Tahoma", topFontSize), Brushes.Blue,
                        new PointF(barOrigin.X, barOrigin.Y - 3 * topFontSize/2));
                    barOrigin.X = barOrigin.X + (barWidth * 2);
                }

                //设置边  
                g.DrawLine(new Pen(Color.Blue, 2), new Point(left, top),
                    new Point(left, height - top));

                g.DrawLine(new Pen(Color.Blue, 2), new Point(left, height - top),
                    new Point(left + width, height - top));

                g.Dispose();
                return bm;
            }
            catch
            {
                return bm;
            }
        }
