plotly简单绘制柱状图

代码：

import plotly.offline as pltoff
import plotly.graph_objs as go


 
def bar_charts(name="bar_charts.html"):
    dataset = {'amount  price  avg_cost':['set_slippage / no_slippage'],
        'y1':amount,  # amount
        'y2':price,  # price
        'y3':avg_cost}  # avg_cost
    data_g = []
    
    # amount
    tr_y1 = go.Bar(
        x = dataset['amount  price  avg_cost'],
        y = dataset['y1'],
        name = 'amount')
    data_g.append(tr_y1)
     
    # price
    tr_y2 = go.Bar(
        x = dataset['amount  price  avg_cost'],
        y = dataset['y2'],
        name = 'price')
    data_g.append(tr_y2)
    
    # avg_cost
    tr_y3 = go.Bar(
        x = dataset['amount  price  avg_cost'],
        y = dataset['y3'],
        name = 'avg_cost')
    data_g.append(tr_y3)
    
    layout = go.Layout(title="设置滑点/不设置滑点模拟盘对比",
        xaxis={'title':'amount  price  avg_cost'}, yaxis={'title':'相除后的值'})
    fig = go.Figure(data=data_g, layout=layout)
#     pltoff.plot(fig, filename=name)  # 保存成 html
    plotly.offline.init_notebook_mode()
    plotly.offline.iplot(fig,filename='basic-scatter')
    
 
if __name__=='__main__':
    bar_charts()

# amount  price avg_cost 为列表数值 自己根据需求填充即可
