K线图

Python绘制K线图之可视化神器pyecharts的使用

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()

  yaxis_opts=opts.AxisOpts(

   )
  )
 )

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。
