Download as PNG not working for scatter3d network map

[GaborSzalai]

The Download as PNG button produces an error "Sorry there was a problem downloading your png" on a scatter3d visualisation in a shiny app.
App is available here: https://gman-works.shinyapps.io/3D_Mapping/
Tested on Chrome and Opera.

Interesting. Thanks very much for the report.

I copied your graph's data and layout and try the Plotly.downloadImage in our dev playground and it worked.

So I'm thinking there's something up with Plotly.downloadImage that makes it not work in all environments (just as reported in #683).

I had to guess, this issue might be related to commit b0f6230

@GaborSzalai upon further inspection, I noticed that your app is using plotly.js 1.8.0 not the latest (1.14.1 as of today).

The bug you're describing has been fixed since 1.13.0 via PR #604

To image is working fine using in the latest plotly.js release: http://codepen.io/etpinard/pen/XKgObK
