SimpleChart是一个非常简单和简陋的图表生成工具，它能够生成jpg格式的折线图和矩形图 

## 如何使用

    class Program
    {
        static void Main(string[] args)
        {
            Chart chart = new Chart();
            chart.Title = "Title Of Chart";
            chart.Data = GetTestData();
            chart.AxisXMember = "X";

            ColumnSeries columnSeries = new ColumnSeries() { Name = "ColumnSeries",
                AxisType = AxisYType.Left,
                AxisYMember = "Y1",
                Color = Color.Red};

            LineSeries lineSeries1 = new LineSeries() { Name = "LineSeries1",
                AxisType = AxisYType.Right,
                AxisYMember = "Y2",
                Color = Color.Purple,
                CirclePointColor = Color.Green,
                ShowCirclePoint = true,
                ShowValueLabel = true };

            LineSeries lineSeries2 = new LineSeries() { Name = "LineSeries2",
                AxisType = AxisYType.Right,
                AxisYMember = "Y3",
                Color = Color.Blue };

            chart.SeriesCollection.Add(columnSeries);
            chart.SeriesCollection.Add(lineSeries1);
            chart.SeriesCollection.Add(lineSeries2);

            Image image = chart.GetImage();
            image.Save("d:\\chart.jpg");
        }

        private static DataTable GetTestData()
        {
            DataTable dt = new DataTable();
            dt.Columns.Add("X");
            dt.Columns.Add("Y1");
            dt.Columns.Add("Y2");
            dt.Columns.Add("Y3");

            Random random = new Random();
            for (int i = 0; i < 5; i++)
            {
                DataRow row = dt.NewRow();
                row[0] = "X" + i;
                row[1] = random.Next(100);
                row[2] = random.Next(10) / 100f;
                row[3] = random.Next(10) / 100f;
                dt.Rows.Add(row);
            }

            return dt;
        }
    }

## 不足之处

为了追求简单快速，代码或功能有如下不足：

- 只支持显示≥0.00000001的数字
- 未做任何数据正确性校验
- 数据只能以DataTable类型传递
- 有多少数据就显示多少个坐标点，未提供Interval属性
- 纵坐标刻度写死为10个，且最大值为0.0000000000000001的10乘以N倍（N≥1）
