使用 pyecharts 渲染成圖檔一直是開發者比較關心的功能,pyecharts提供了 selenium、phantomjs 和 pyppeteer 三種方式。

首先需要安裝上snapshot-selenium
pip install snapshot-selenium -i http://pypi.douban.com/simple --trusted-host pypi.douban.com
複制
測試代碼如下:
from pyecharts.render import make_snapshot
from snapshot_selenium import snapshot
from pyecharts import options as opts
from pyecharts.charts import Sankey
sankey = Sankey(
init_opts=opts.InitOpts(
width='1000px',
height='600px',
bg_color='#fff'
)
)
sankey.add(
'',
nodes,
links,
node_gap=0,
node_width=80,
pos_right='5%',
node_align='justify',
focus_node_adjacency=True,
linestyle_opt=opts.LineStyleOpts(curve=0.5, opacity=0.2, color="source"),
label_opts=opts.LabelOpts(position='inside', color='white'),
itemstyle_opts=opts.ItemStyleOpts(border_color="#fff"),
)
print(":".join(["CSDN葉庭雲", "https://yetingyun.blog.csdn.net/"]))
# sankey.render("./results/009.html")
make_snapshot(snapshot, sankey.render(), "Pyecharts生成圖檔.png")
複制
關鍵代碼:
from pyecharts.render import make_snapshot
from snapshot_selenium import snapshot
# 渲染的html儲存為png圖檔
make_snapshot(snapshot, sankey.render(), "Pyecharts生成圖檔.png")
複制
結果如下:
