方法：

InitTable 方法：负责初始化图表模型，包括设置图表的样式、坐标轴、系列和注释。这个方法包括多个 Init 方法的调用，表示图表的初始化过程可以分步骤进行。
InitGoalPoint 方法：当前未实现，但预留了子类进行重写。
InitX 和 InitY 方法：分别初始化 X 和 Y 轴。
AddPoint 方法：向图表中添加点，并更新 Y 轴的最大值。
ClearPoint 方法：清空图表中的点并重新绘制。

字段和属性：

使用了 protected 修饰符来保护图表的各个部分（如 X 轴、Y 轴、系列等），允许子类访问和修改。
DataSrc 是一个公开的字典，用于存储数据源。
ChartModel 是公开的，只读属性，返回当前的图表模型。
GoalLines 也是公开的，只读属性，返回目标线的集合。
