上两篇文章《基于Pyecharts可视化大屏案例一（1）》《基于Pyecharts可视化大屏案例一（2）》已经为大家详细展示了大屏大致的制作过程以及可视化大屏的布局，接下来继续完善。我们先来回顾下完整的精美大屏：

请看下本文在上两文基础上制作左上图形的最终效果：

放大展示（注意放大后需要F5刷新一下）：

接下来，就开始漫长的......

1. 加载一箩筐的库

from pyecharts.charts import Page,Bar,Line,Grid,Pieimport pyecharts.options as optsfrom pyecharts.globals import ThemeTypefrom pyecharts.faker import Fakerfrom pyecharts.commons.utils import JsCodeimport pandas as pdimport numpy as npimport randomfrom bs4 import BeautifulSoup

2. 生成随机数据

names = ['店员_'+str(i) for i in range(1,51)] #生成n个店员的名字sales = [random.randint(10,100) for _ in range(50)] #随机生成n个数字，代表店员销售额df = pd.DataFrame() #生成一个空DataFrame()df['店员'] = names df['销售额'] = salesdf.sort_values(by='销售额',ascending=False,inplace=True) #按销售额从小到大排序data_pair = [] #生成画图需要的数据格式for i,j in zip(df['店员'],df['销售额']):    list_ = [i,j]    data_pair.append(list_)

3. 不加任何参数绘制饼图

# 画图pie = ( Pie() .add( series_name='店员销售额', data_pair=data_pair, )).render('test.html')

4. 去掉legend和设置标题

# 画图pie = (    Pie()    .add(        series_name='店员销售额',        data_pair=data_pair,    )    .set_global_opts(        title_opts=opts.TitleOpts(            title='导购员成交销售额',            pos_left='center',            pos_top='0%',            title_textstyle_opts=opts.TextStyleOpts(color='pink',font_size = 20,),        ),        legend_opts=opts.LegendOpts(            is_show = False,        ),    )).render('test.html')

5. 设置饼图类型为南丁格尔玫瑰图、圆心位置，以及空心的大小

# 画图pie = ( Pie() .add( series_name='店员销售额', data_pair=data_pair, rosetype='radius', #类型为南丁格尔玫瑰图 radius=['10%','60%'], center=['center', 'center'], #设置圆心位置 ) .set_global_opts( title_opts=opts.TitleOpts( title='导购员成交销售额', pos_left='center', pos_top='0%', title_textstyle_opts=opts.TextStyleOpts(color='pink',font_size = 20,), ), legend_opts=opts.LegendOpts( is_show = False, ), )).render('test.html')

6. 设置标签，加上百分比

# 画图pie = (    Pie()    .add(        series_name='店员销售额',        data_pair=data_pair,        rosetype='radius', #类型为南丁格尔玫瑰图        radius=['10%','60%'],        center=['center', 'center'], #设置圆心位置    )    .set_global_opts(        title_opts=opts.TitleOpts(            title='导购员成交销售额',            pos_left='center',            pos_top='0%',            title_textstyle_opts=opts.TextStyleOpts(color='pink',font_size = 20,),        ),        legend_opts=opts.LegendOpts(            is_show = False,        ),    )    .set_series_opts(        label_opts=opts.LabelOpts(formatter='{b}: {c}万'),        tooltip_opts=opts.TooltipOpts(            trigger='item', formatter='{a} <br/>{b}: {c}万 ({d}%)'        ),    )).render('test.html')

7. 通过grid()设置背景

grid = ( Grid( init_opts=opts.InitOpts( theme = ThemeType.WONDERLAND #设置主题 ) ) .add(pie, grid_opts=opts.GridOpts(pos_left='0%',)) #调整位置).render('test.html')

8. 添加到大屏上

def get_grid_3():    names = ['店员_'+str(i) for i in range(1,101)] #生成100个店员的名字    sales = [random.randint(10,100) for _ in range(100)] #随机生成100个数字，代表店员销售额    df = pd.DataFrame() #生成一个空DataFrame()    df['店员'] = names     df['销售额'] = sales    df.sort_values(by='销售额',ascending=False,inplace=True) #按销售额从小到大排序    data_pair = [] #生成画图需要的数据格式    for i,j in zip(df['店员'],df['销售额']):        list_ = [i,j]        data_pair.append(list_)        # 画图    pie = (        Pie()        .add(            series_name='店员销售额',            data_pair=data_pair,            rosetype='radius', #类型为南丁格尔玫瑰图            radius=['10%','60%'],            center=['center', 'center'], #设置圆心位置        )        .set_global_opts(            title_opts=opts.TitleOpts(                title='导购员成交销售额',                pos_left='center',                pos_top='0%',                title_textstyle_opts=opts.TextStyleOpts(color='pink',font_size = 20,),            ),            legend_opts=opts.LegendOpts(                is_show = False,            ),
        )        .set_series_opts(            label_opts=opts.LabelOpts(formatter='{b}: {c}万'),            tooltip_opts=opts.TooltipOpts(                trigger='item', formatter='{a} <br/>{b}: {c}万 ({d}%)'            ),        )    )        grid = (        Grid(            init_opts=opts.InitOpts(                theme =  ThemeType.WONDERLAND #设置主题            )        )        .add(pie, grid_opts=opts.GridOpts(pos_left='0%',)) #调整位置    )        return grid
def get_page():    grid3 = get_grid_3()        page = (        Page()        .add(grid3)    )
    return page
if __name__ == '__main__':    page = get_page()    page.render('test.html')        with open('test.html', 'r+', encoding='utf-8') as html:            html_bf = BeautifulSoup(html, 'lxml')        divs = html_bf.select('.chart-container')        divs[0]['style'] = 'width:550px;height:400px;position:absolute;top:540px;left:30px;border-style:solid;border-color:#444444;border-width:0px;'                body = html_bf.find('body')        body['style'] = 'background-color:#07645D;' #设置网页背景颜色        div_title='<div align=\'center\' style=\'width:1824px;\'>\n<span style=\'font-size:64px;font face=\'黑体\';color:#66FFFF\'><b>2020年销售数据分析</b></div>'    #修改页面背景色、追加标题        body.insert(0,BeautifulSoup(div_title,'lxml').div)
        html_new = str(html_bf)        html.seek(0, 0)        html.truncate()        html.write(html_new)        html.close()

9. 最后附上含三张图片的可视化大屏代码
