问题

您好，我希望利用pyecharts生成svg格式，但转换后的svg文件无法显示图片，请问这个是因为没有加入渲染，还是什么问题嘛

Code

from pyecharts import options as opts
from pyecharts import render
from pyecharts.charts import Bar
from pyecharts.globals import RenderType
from pyecharts.render import make_snapshot

from snapshot_phantomjs import snapshot
//from snapshot_selenium import snapshot

def bar_chart() -> Bar:
c = (
Bar()
.add_xaxis(["衬衫", "毛衣", "领带", "裤子", "风衣", "高跟鞋", "袜子"])
.add_yaxis("商家A", [114, 55, 27, 101, 125, 27, 105])
.add_yaxis("商家B", [57, 134, 137, 129, 145, 60, 49])
.reversal_axis()
.set_series_opts(label_opts=opts.LabelOpts(position="right"))
.set_global_opts(title_opts=opts.TitleOpts(title="Bar-测试渲染图片"))
)
return c

make_snapshot(snapshot, bar_chart().render(), "bar0.svg")

bar_chart().render('bar0.html')
make_snapshot(snapshot, 'bar0.html', "bar0.svg")

命令行

通过命令行 snapshot bar0.html svg 方式获取，同样打开是如下格式

SVG打开后：

This XML file does not appear to have any style information associated with it. The document tree is shown below.

<canvas data-zr-dom-id="zr_0" width="900" height="500" style="position: absolute; left: 0px; top: 0px; width: 900px; height: 500px; user-select: none; -webkit-tap-highlight-color: rgba(0, 0, 0, 0); padding: 0px; margin: 0px; border-width: 0px;"/>

运行Example programs报错“IndexError: list index out of range”

`IndexError Traceback (most recent call last)
in ()
11 bar.add("商家B", attr, v2, is_stack=True)
12 bar.render()

我生成了一个动态图表，在以html为格式时可交互也可以动态，但是输出成gif或者svg就不能动态和交互，而且README中的svg示例已经挂了...

When I run a html file using "snapshot render.html svg", what are the some errors ? How to resovle it?

Hi,
I'm trying to run pyecharts-snapshot inside my WSL2-ubuntu env and for this reason there is no browser. Is there any workaround?

在完整的一个ipynb中，需要多次调用make_a_snapshot生成png图片，这导致在程序运行一部分时，电脑内存爆掉，所以希望优化下性能。之前直接利用bar或者line直接生成，未出现此问题，但是导出为PDF不能显示。

测试代码

from pyecharts import options as opts
from pyecharts.charts import Bar
from pyecharts.render import make_snapshot

from snapshot_phantomjs import snapshot

def bar_chart() -> Bar:
    c = (
        Bar()
        .add_xaxis(["衬衫", "毛衣", "领带", "裤子", "风衣", "高跟鞋", "袜子"])
        .add_yaxis("商家A", [114, 55, 27, 101, 125, 27, 105])

i want to use it in python to turn encharts.html into png, how can i do this?

我单独运行命令也不行 这什么原因 phantomjs版本吗

描述：
pyecharts将图片保存成jpeg的时候，背景色变成黑色。
保存成png则没有问题，但是图片没有压缩，9M太大了。

版本：
pyecharts 0.5.11
pyecharts-snapshot 0.1.10

图片：

代码：
bar_image = pyecharts.Bar(”title‘’, width=1200, height=700)
bar_image.add(‘long’, long_interval_array,
long_frequency_array)
bar_image.add('short', short_interval_array,
short_frequency_array)

bar_image.render(path='test.jpeg')

In my python, it seems that the delay wouldn't work. No matter what kinds of number I type in, it just wouldn't work. And the pic it generates is damaged. I can't open it. But the html file is ok. Weird.

在html文件加载完成后的效果：

png文件：

Vector graphics are essential for organizing the figures in manuscript. Can sankey plot be converted to vectorgraph like pdf or SVG file? Thanks a lot!

Windows 7 with Python 2.7, with the latest pyecharts and pyecharts-snapshot from github.

1. Using forward slash in path or any path generated with os.path module won't work. Change it to back slash works.
2. Chinses name in the full absolute file path won't work.

when I run snapshot test.html gif in command line , It gives me a static picture, not a gif, How can I got a dynamic gif file?

我已经照着安装了，怎么还有bug？
1.安装了 node.js 环境
2.安装 phantomjs
npm install -g phantomjs-prebuilt
3.安装 pyecharts-snapshot
pip install pyecharts-snapshot
4.引入 pyecharts-snapshot
from pyecharts_snapshot.main import make_a_snapshot
make_a_snapshot('render.html', 'snapshot.png')’

I use python2.7.10 run this https://github.com/pyecharts/pyecharts-snapshot/blob/master/examples/pdf.py file , can't get right pdf file, change output file name to *.html ,then can see the right graph. no errors. i installed pyecharts-snapshot, pyecharts and phantomjs.

how can I get right file? thank your.

mac os phantomjs already setup. python3.7

画图代码为：
file_path="{}/".format(os.path.dirname(os.path.abspath("./echarts.min.js")))
def scatter3d() -> Scatter3D:
c = (
Scatter3D(init_opts = opts.InitOpts(width='900px',height='700px', js_host=file_path))

)
return c

scatter3d_png = os.path.join(od_path, "Scatter3D_vdj_pairs.png")
make_snapshot(snapshot, scatter3d().render(), scatter3d_png)
生成的PNG是空的。

我把echarts.min.js下载到linux，Sankey图按照这个模式是可以生成PNG 和PDF的，但是Scatter3D不知道为什么不行

盼复

在分布式场景下，只能直接返回图片，能否添加一个函数，直接返回图片base64的编码？ 最好不要复用render 方法

我的一个ipynb中，多次利用了make_a_snapshot，前面的十几个图片可以截图成功，到13张图片的时候，就开始报错No phantomjs found in your PATH. Please install it!

An exception has occurred, use %tb to see the full traceback.

SystemExit: 1

我的phantomjs已经安装好了，前面的截图也已经成功了，不知道为什么中途就出问题了

@chfw Have you updated this on pypi yet?

File "grid.py", line 4, in
from pyecharts import Bar, Grid, Line, Scatter, EffectScatter

在issue 23看到跟我同样报错的信息，看到作者提交了commit和终止了问题后
我把作者的回复操作试了一遍
但是发现还是没有成功解决我的 问题
这是我的错误信息

使用的是有我自己的代码和作者的案例代码，还有尝试了作者说的引擎方式，但都是同样的错误
无论是这个案例

还是这个案例
`from pyecharts import Bar, Line
from pyecharts.engine import create_default_environment

bar = Bar("我的第一个图表", "这里是副标题")
bar.add("服装", ["衬衫", "羊毛衫", "雪纺衫", "裤子", "高跟鞋", "袜子"], [5, 20, 36, 10, 75, 90])

line = Line("我的第一个图表", "这里是副标题")
line.add("服装", ["衬衫", "羊毛衫", "雪纺衫", "裤子", "高跟鞋", "袜子"], [5, 20, 36, 10, 75, 90])

env = create_default_environment("html")

为渲染创建一个默认配置环境

create_default_environment(filet_ype)

file_type: 'html', 'svg', 'png', 'jpeg', 'gif' or 'pdf'

env.render_chart_to_file(bar, path='bar.html')
env.render_chart_to_file(line, path='line.html')`
都是报了同一个错误
我的尝试结果是，如果不用引擎的方式，我可以生成html文件，但是png文件始终无法生成

我的python版本是3.6
使用的是sublime text编辑器
版本信息有
pyecharts==0.5.11
pyecharts-javascripthon==0.0.6
pyecharts-jupyter-installer==0.0.3
pyecharts-snapshot==0.1.7
PyInstaller==3.3.1

以上是我的问题详细内容，跪求作者翻牌，谢谢大佬

pyecharts-snapshot 0.1.10 everything is ok.

hello,every friends, I have a problem now, who can help me? thanks very much~
when I create a html file the legend is intact, but when I use the snapshot to create a png/gif, the title、the lables and the legend are all disappear.

怎么正确在Gauge(init_opts=opts.InitOpts(bg_color="white"))中opts_InitOpts添加js_host使得代码能运行？

如题，不然会出现截图缺失问题，就不提交 PR 了，你自己修改就行了 @chfw

如题，不过make_a_snapshot的方法可以使用。

I used snapshot to generate a chart, png format, the file size is about 12M+. Is there any approach to reduce the file size? Thank you!
