趋势线
---- 有句话怎么说来着,“只有趋势才是你的朋友”。
---- 对任意一点可以辨认它所处的趋势。算法保证如果 A 点和 B 点的趋势起点都在 O,那么 A、B 之间任意一点的趋势起点也在 O 点。
用 Python / Matplotlib 画出来的股票 K线图 (三)

---- 就像上回说的,新内容加进来。除此之外,与上一版代码相比最大的改动就是内部重构过,子图全部定义成 class。图中一共包含 5 个子图,从上到下依次是: 基本信息(就是那些文字)、历史价格、历史换手率、价格、换手率。通过输入的绘图数据进行控制,任何一个子图都可以关闭,关闭子图可以节省绘图时间和存储空间。本来还有一个财务信息子图要加进去,但是现在想暂时告一段落,先弄点其它的。
---- 作为输入的 Python pickle file 在 这里。
---- 最后是脚本,仍然是 Python 2 的:

用 Python / Matplotlib 画出来的股票 K线图 (二)
---- 最新的在这里: 用 Python / Matplotlib 画出来的股票 K线图 (四)
---- 下一篇在这里: 用 Python / Matplotlib 画出来的股票 K线图 (三)
---- 上一版的改进,双股同列 + 无数细小改进,如下图。dpi= 300。明的一条是个股走势,暗的是同期的指数走势。这大概是近期最强的一只。
---- 要想培养对走势的感觉,采用固定比例尺的图形是必须的。一般股票软件里的图形都为显示方便而做了变形处理,用处不大。
---- 图形感觉差不多了,告一段落。接下来的目标是 股本结构、历史分配、行业板块、股东研究 这些信息,还包括个股资讯。实时的数据仍然暂时不碰。
---- 源码贴出来。因为 Matplotlib 还不支持 Python3, 所以单写了一个 Python2 脚本。注意绘图数据是用 pickle file 传递的。
[补记:我决定放弃线性坐标了。这个脚本只支持对数坐标。]
