Python绘制K线图之可视化神器pyecharts的使用

K线图

概念

股市及期货市bai场中的K线图的du画法包含四个zhi数据，即开盘dao价、最高价、最低价zhuan、收盘价，所有的shuk线都是围绕这四个数据展开，反映大势的状况和价格信息。如果把每日的K线图放在一张纸上，就能得到日K线图，同样也可画出周K线图、月K线图。研究金融的小伙伴肯定比较熟悉这个，那么我们看起来比较复杂的K线图，又是这样画出来的，本文我们将一起探索K线图的魅力与神奇之处吧！

K线图

用处

K线图用处于股票分析，作为数据分析，以后的进入大数据肯定是一个趋势和热潮，K线图的专业知识，说实话肯定比较的复杂，这里就不做过多的展示了，有兴趣的小伙伴去问问百度小哥哥哟！

K线图系列模板

最简单的K线图绘制

第一个K线图绘制，来看看需要哪些参数吧，数据集都有四个必要的哟！

import pyecharts.options as opts
from pyecharts.charts import Candlestick
 
x_data = ["2017-10-24", "2017-10-25", "2017-10-26", "2017-10-27"]
y_data = [[20, 30, 10, 35], [40, 35, 30, 55], [33, 38, 33, 40], [40, 40, 32, 42]]
 
(
 Candlestick(init_opts=opts.InitOpts(width="1200px", height="600px"))
 .add_xaxis(xaxis_data=x_data)
 .add_yaxis(series_name="", y_axis=y_data)
 .set_series_opts()
 .set_global_opts(
  yaxis_opts=opts.AxisOpts(
   splitline_opts=opts.SplitLineOpts(
    is_show=True, linestyle_opts=opts.LineStyleOpts(width=1)
   )
  )
 )
 .render("简单K线图.html")
)

K线图鼠标缩放

大量的数据集的时候，我们不可以全部同时展示，我们可以缩放来进行定向展示。

有刻度标签的K线图

我们知道一个数据节点，但是我们不能在图像里面一眼看出有哪些数据量超出了它的范围，刻度标签就可以派上用场了。

K线图鼠标无缩放

前面的是一个有缩放功能的图例代码，但是有时候我们不想要那么修改一下参数就可以了。

大量数据K线图绘制（X轴鼠标可移动）

虽然有时候缩放可以容纳较多的数据量，但是还是不够智能，可以利用这个

K线图的绘制需要有专业的基本知识哟，不然可能有点恼火了。
