Python数据可视化
利用pyecharts做数据大屏dashboard
首先做一个折线图
代码语言：javascript复制import os
from pyecharts import options as opts
from pyecharts.charts import Line
from pyecharts.globals import ThemeType
from main import tbsi_total
def Line_todayfund():
r = tbsi_total() # 取出我的基金持仓并计算
attr = [i[0] for i in r]
v1 = [round(i[1], 2) for i in r]
# 主题调成紫色 报表id设置是为了后面整体布局用
line = (Line(init_opts=opts.InitOpts(theme=ThemeType.PURPLE_PASSION, chart_id=1))
# 添加横坐标
.add_xaxis(attr)
# 添加数据
.add_yaxis("", v1, is_smooth=True, is_symbol_show=False,
markpoint_opts=opts.MarkPointOpts(
data=[
opts.MarkPointItem(type_="max", name="最大值"),
opts.MarkPointItem(type_="min", name="最小值"),
]
),
markline_opts=opts.MarkLineOpts(
data=[opts.MarkLineItem(type_="average", name="平均值")]
),
)
.set_global_opts(title_opts=opts.TitleOpts(title="实时收益", subtitle="基金收益"),
# 鼠标悬浮显示数值 纵坐标
axispointer_opts=opts.AxisPointerOpts(
is_show=True, link=[{"xAxisIndex": "all"}]
),
# 鼠标悬浮显示数值 横坐标
tooltip_opts=opts.TooltipOpts(trigger="axis"),
# 增加横坐标区域缩放
datazoom_opts=[
opts.DataZoomOpts(
is_show=True,
is_realtime=True,
# 起始范围
range_start=0,
# 结束范围
range_end=100
)
],
))
return line
line = Line_todayfund()
line.render('line.html')
os.system('line.html')获取数据部分不是重点我这边就不展示了
饼图
代码语言：javascript复制import os
from pyecharts import options as opts
from pyecharts.charts import Pie
from pyecharts.globals import ThemeType
from main import fund_count
def Pip_fundcount():
r = fund_count() # 取出我的基金持仓并计算
x_data = [i[0] for i in r]
y_data = [abs(i[1]) for i in r]
data_pair = [list(z) for z in zip(x_data, y_data)]
# 为了好看先排序了一下
data_pair.sort(key=lambda x: x[1])
# 主题调成紫色 报表id设置是为了后面整体布局用
pie = (Pie(init_opts=opts.InitOpts(theme=ThemeType.PURPLE_PASSION, chart_id=2))
.add(
"",
data_pair,
# 是否玫瑰图 有两种 radius：扇区圆心角展现数据的百分比，半径展现数据的大小
# area：所有扇区圆心角相同，仅通过半径展现数据大小
rosetype="radius",
# 图表圆形半径
radius="55%",
# 距离左右距离
center=["50%", "50%"],
)
# 数据整体样式
.set_global_opts(title_opts=opts.TitleOpts(
title="持仓分布",
pos_left="center",
# 距离标题距离
pos_top="25",
),
# 最上方图例组件隐藏
legend_opts=opts.LegendOpts(is_show=False),
)
)
return pie
pie = Pip_fundcount()
pie.render('pie.html')
os.system('pie.html')
柱状图
代码语言：javascript复制import os
from pyecharts import options as opts
from pyecharts.charts import Bar
from pyecharts.globals import ThemeType
from main import fund_count
def Bar_fundactral():
r = fund_count() # 数据准备
x_data = [i[0] for i in r]
y_data = [abs(i[1]) for i in r]
bar = (
# 主题调成紫色 报表id设置是为了后面整体布局用
Bar(init_opts=opts.InitOpts(theme=ThemeType.PURPLE_PASSION, chart_id=3))
# 添加横坐标
.add_xaxis(x_data)
# 纵坐标数据
.add_yaxis("收益", y_data)
# 旋转横纵坐标
.reversal_axis()
.set_global_opts(
# 横坐标放不下数据 旋转字体
# xaxis_opts=opts.AxisOpts(axislabel_opts=opts.LabelOpts(rotate=-40)),
# 标题 副标题
title_opts=opts.TitleOpts(title="持有收益", subtitle="昨日净值算"),
# 纵坐标范围筛选
datazoom_opts=opts.DataZoomOpts(orient="vertical",
# 起始范围
range_start=0,
# 结束范围
range_end=100
),
# 最上方图例组件隐藏
legend_opts=opts.LegendOpts(is_show=False),
)
.set_series_opts(
label_opts=opts.LabelOpts(position="right"),
)
)
return bar
bar = Bar_fundactral()
bar.render('bar.html')
os.system('bar.html')
水球图
代码语言：javascript复制import os
from pyecharts import options as opts
from pyecharts.charts import Liquid
from pyecharts.commons.utils import JsCode
from pyecharts.globals import ThemeType
def Liquid_limit():
liquid = (
Liquid(init_opts=opts.InitOpts(theme=ThemeType.PURPLE_PASSION, chart_id=4))
.add(
"",
[0.3254],
label_opts=opts.LabelOpts(
font_size=50,
formatter=JsCode(
"""function (param) {
return (Math.floor(param.value * 10000) / 100) '%';
}"""
),
position="inside",
),
)
.set_global_opts(title_opts=opts.TitleOpts(title="剩余额度"))
)
return liquid
liquid = Liquid_limit()
liquid.render('liquid.html')
os.system('liquid.html')
词云图
代码语言：javascript复制import os
from pyecharts import options as opts
from pyecharts.charts import WordCloud
from pyecharts.globals import ThemeType
from api.bk_api import bk_word
def wordcloud_fund():
data = bk_word() #数据获取
word = (
WordCloud(init_opts=opts.InitOpts(theme=ThemeType.PURPLE_PASSION, chart_id=5))
.add(series_name="热点分析", data_pair=data, word_size_range=[6, 66])
.set_global_opts(
title_opts=opts.TitleOpts(
title="热点分析", title_textstyle_opts=opts.TextStyleOpts(font_size=23)
),
tooltip_opts=opts.TooltipOpts(is_show=True),
)
)
return word
word = wordcloud_fund()
word.render('word.html')
os.system('word.html')
结合在一起
代码语言：javascript复制def Page_total():
page = (
Page(layout=Page.DraggablePageLayout)
.add(
Line_todayfund(),
Pip_fundcount(),
Bar_fundactral(),
Liquid_limit(),
wordcloud_fund(),
)
)
page.render('page.html')
Page_total()
os.system('page.html')把图表拖拉成自己想要的样式和位置 然后保存成json格式的文件
def Page_total():
page = (
Page(layout=Page.DraggablePageLayout)
.add(
Line_todayfund(),
Pip_fundcount(),
Bar_fundactral(),
Liquid_limit(),
wordcloud_fund(),
)
)
page.render('page.html')
Page.save_resize_html('page.html',
cfg_file='chart_config.json',
dest='dashboard.html')
Page_total()
os.system('dashboard.html')
这就是运行好后的数据大屏 （数据来源:天天基金网）
