renders pyecharts output as image
Project description
News - 16.04.2019
Since 0.2.0, NO LONGER, phantomjs is required! NO LONGER, it supports python 2.7
BUT, the capability to render pyecharts in a script has been merged into pyecharts 1.0.0. And the dependency on phantomjs has been sprawn as: snapshot-phantomjs .
If you love to use ‘snapshot’ command line, please continue to use this project.
Introduction
pyecharts-snapshot renders the output of pyecharts/echarts.js as a png, jpeg, gif, eps, svg image, raw base64 encoding or a pdf file at command line.
Usage
Get png:
$ snapshot render.htmlAnd you will get:
Get pdf:
$ snapshot render.html pdfAnd you will get:
And here the code to generate it
Get svg:
$ snapshot render.html svgPlease be aware that render.html should have configure echarts to do svg rendering. This library, being stupid, does not make canvas rendered image as svg rendered. Here is an example svg file.
Usage details
Command line options:
$ snapshot output.html [png|jpeg|gif|svg|pdf] [delay] [pixel ratio]
where:
delay tells pyecharts-snapshot to take a snapshot after some time measured in seconds. It is needed only when your snapshot is partial because the chart animation takes long than 1.5 second(default). pixel ratio tells pyecharts-snapshot to use a different pixel ratio when generate the image. It defaults to 2.
Programmatical usage is simple:
...
somechart.render(path='cool_snapshot.png') # delay=1, pixel_ratio=3) 1 second delay, 3 as pixel ratiowhere delay as an optional parameter can be given to specify delay_in_seconds.
Coffee
Please buy me a coffee if you think this library helped.
