pyecharts库绘制：条形图、折线图、饼图、环形图、散点图及相应参数设置

import pyecharts
pyecharts.__version__ #版本检查

import pyecharts.charts as pyec
x=['甲','乙','丙']
y=[300,800,600]

bar=pyec.Bar()
bar.add_xaxis(x)
bar.add_yaxis(series_name='A',yaxis_data=y)
bar.render_notebook()

增加一个数据系列

y1=[344,677,690]
bar.add_yaxis(series_name='B',yaxis_data=y1)
bar.render_notebook()

加一些配置选项-标题

import pyecharts.options as opts
bar.set_global_opts(title_opts=opts.TitleOpts(title='比较图'))
bar.render_notebook()

折线图

x1=['2017','2018','2019']
y1=[300,400,600]
line=pyec.Line()
line.add_xaxis(x1)
line.add_yaxis(series_name='A',y_axis=y1)
line.render_notebook()

增加一条折线

y2=[1300,500,900]
line.add_yaxis(series_name='B',y_axis=y2)
line.render_notebook()

line增加提示项
进行该图的全局参数设置

line.set_global_opts(
title_opts=opts.TitleOpts(title='第一幅图'),
tooltip_opts=opts.TooltipOpts(trigger='axis',axis_pointer_type='cross'))

line.render_notebook()

Line工具箱设置

line.set_global_opts(
title_opts=opts.TitleOpts(title='第一幅图'),
tooltip_opts=opts.TooltipOpts(trigger='axis',axis_pointer_type='cross'),#
toolbox_opts=opts.ToolboxOpts(is_show=True,orient='horizontal')) #工具箱设置 orient=vertical让工具箱水平放置

line.render_notebook()

设置图表大小

x1=['2017','2018','2019']
y1=[300,400,600]
line1=pyec.Line(init_opts=opts.InitOpts(width='500px',height='300px'))
line1.add_xaxis(x1)
line1.add_yaxis(series_name='C',y_axis=y1)
line1.render_notebook()

pie饼图

#构造pie的数据
x_data=['a','b','c','d']
y_data=[345,764,654]
#pie设置指定格式
data_pair=list(zip(x_data,y_data))
print(data_pair)

[(‘a’, 345), (‘b’, 764), (‘c’, 654)]

pie=pyec.Pie()
pie.add(series_name='dfdf',data_pair=data_pair)
pie.render_notebook()

环形图

pie1=pyec.Pie()
pie1.add(series_name='dfdf',data_pair=data_pair,radius=['40%','75%'])

pie1.render_notebook()

散点图

import numpy as np
import matplotlib.pyplot as plt
x=np.linspace(0,10,30)
y1=np.sin(x)
y2=np.cos(x)
plt.scatter(x,y1)

scatter=pyec.Scatter()
scatter.add_xaxis(xaxis_data=x)
scatter.add_yaxis(series_name='y=sin(x)',y_axis=y1,)
scatter.render_notebook()

scatter=pyec.Scatter()
scatter.add_xaxis(xaxis_data=x)
scatter.add_yaxis(series_name='y=sin(x)',y_axis=y1,
                 label_opts=opts.LabelOpts(is_show=False))#设置数据是否展示
scatter.render_notebook()

scatter.add_yaxis(
series_name='y=cos(x)',
y_axis=y2,
label_opts=opts.LabelOpts(is_show=False))

                 
scatter.render_notebook()

控制散点大小

scatter=pyec.Scatter()
scatter.add_xaxis(xaxis_data=x)
scatter.add_yaxis(series_name='y=sin(x)',y_axis=y1,
                 label_opts=opts.LabelOpts(is_show=False),#设置数据是否展示
                 symbol_size=30,#控制散点图点的大小
                 symbol='roundRect',#散点形状
                 )
scatter.render_notebook()
