plotly绘制简单图形<10>--金字塔图
为了参照对比,我们一般需要画类似金字塔形状的图表来展示数据,
下面我们那一个例子来看一下效果
import plotly.plotly as py import plotly.graph_objs as go import numpy as np women_bins = np.array([-600, -623, -653, -650, -670, -578, -541, -411, -322, -230]) men_bins = np.array([600, 623, 653, 650, 670, 578, 541, 360, 312, 170]) y = list(range(0, 100, 10)) layout = go.Layout(yaxis=go.layout.YAxis(title='Age'), xaxis=go.layout.XAxis( range=[-1200, 1200], tickvals=[-1000, -700, -300, 0, 300, 700, 1000], ticktext=[1000, 700, 300, 0, 300, 700, 1000], title='Number'), barmode='overlay', bargap=0.1) data = [go.Bar(y=y, x=men_bins, orientation='h',#水平条形图需设置,竖直条形图不用设置 name='Men', hoverinfo='x', marker=dict(color='#808080')#设置颜色 ), go.Bar(y=y, x=women_bins, orientation='h',#水平条形图需设置,竖直条形图不用设置 name='Women', text=-1 * women_bins.astype('int'),#women的数据标签 hoverinfo='text', marker=dict(color='seagreen') )] py.iplot(dict(data=data, layout=layout))
