您需要对数据进行分组并在图表中以不同的轨迹显示它们。您可以使用DataFrame Subsetting 来执行此操作。做子集的主线就是这样。
df[df['direction'] == 'Increasing']['AAPL.Open']
在df[df['direction'] == 'Increasing'] 部分发生的情况是,我们检查数据帧的direction 列是否等于Increasing 值/类别,如果为真,则对数据帧进行子集化,以便仅存在这些值,然后我们可以通过使用['AAPL.Open']部分选择列来选择要绘制的特定列
请参考以下示例,如果您的问题得到解决,请告诉我!
代码:
import plotly.offline as py
import plotly.graph_objs as go
from plotly.offline import init_notebook_mode, iplot, plot
from plotly import tools
import pandas as pd
import numpy as np
init_notebook_mode(connected=True)
df = pd.read_csv("https://raw.githubusercontent.com/plotly/datasets/master/finance-charts-apple.csv")
opening_increasing = go.Scatter(
x=df.Date,
y=df[df['direction'] == 'Increasing']['AAPL.Open'],
name = "AAPL Opening Price - Increasing",
line = dict(color = '#17BECF'),
opacity = 0.8)
opening_decreasing = go.Scatter(
x=df.Date,
y=df[df['direction'] == 'Decreasing']['AAPL.Open'],
name = "AAPL Opening Price - Decreasing",
line = dict(color = '#7F7F7F'),
opacity = 0.8)
data = [opening_increasing, opening_decreasing]
layout = dict(
title = "Apple Opening Price by Increasing/Decreasing Categories of Direction"
)
fig = dict(data=data, layout=layout)
py.iplot(fig, filename = "Manually Set Range")
输出:
