plotly基于dataframe数据绘制柱状图（bar plot）

# 构建仿真pandas数据；

# 绘制条形图；

import plotly as py # 导入plotly库并命名为pyimport plotly.graph_objs as goimport pandas as pdimport numpy as np# -------------pre defpyplt = py.offline.plotN = 40x = np.linspace(0, 1, N)y = np.random.randn(N)df = pd.DataFrame({'x': x, 'y': y})df.head()data = [go.Bar(x=df['x'], # x可以是 DataFrame 的某一列y=df['y'])]url = pyplt(data, filename=r'basic_bar.html')
