chartify

chartify copied to clipboard

type: bug

Environment:

• Chartify version(s): 2.6.0
• Operating System(s): Windows
• Python version(s): 3.7.1

What happened:

The PNG version of the charts always generate a white square image. The HTML works normally.

What you expected to happen: It was expected to generate the png of the graphic.

How to reproduce it (as minimally and precisely as possible): Install the chrome driver and pipefy and try to generate any chart as png with jupyter

+1 I have the same issue. Can anyone help solving it? Saving to html does work though.

I have the same issue, still not able to figure it out.

+1.

Got this on my Ubuntu server 20.04

Wanted to do a bit debugging here.

screenshot of Chrome debugger connected to webdriver (added options.add_argument('--remote-debugging-port=9222'))

To enable webdriver logs, do this (edit source code for chartify):

driver = webdriver.Chrome(
    options=options,
    # add this
    service_args=[
        "--verbose",
        "--log-path=/home/ubuntu/melcharter/webdriver.log",
    ],
)

webdriver logs:

[1632007907.997][DEBUG]: DevTools WebSocket Command: Page.navigate (id=16) 3A8C277E36F2C399656DAAE2ADBEFBC5 {
   "url": "file:////tmp/chartifyp70vb2rl.html"
}
[1632007908.003][DEBUG]: DevTools WebSocket Response: Page.navigate (id=16) 3A8C277E36F2C399656DAAE2ADBEFBC5 {
   "errorText": "net::ERR_FILE_NOT_FOUND",
   "frameId": "3A8C277E36F2C399656DAAE2ADBEFBC5",
   "loaderId": "BB149E8D4D35D3D49671161BD4FA9881"
}

So, chromium says that there is no such file, but simple stat /tmp/chartifyp70vb2rl.html shows that there is it.

If I change chart path right within chartify sourcecode from /tmp to /home, it works.

This code was patched https://github.com/spotify/chartify/blob/5ac3a88e54cf620389741f396cc19d60fe032822/chartify/_core/chart.py#L433-L471

The reason is snap.

So I just fixed my issue with plots by uninstaling chromium snap version and installing unsnapped version:

• sudo snap remove --purge chromium
• Go to https://askubuntu.com/questions/1204571/how-to-install-chromium-without-snap
