Support for PNG url?

[Deekor]

Does this gem support the png printing functionality? https://developers.google.com/chart/interactive/docs/printing

I would like to just get the URL of a chart to stick into an email.

The gem supports adding listeners now, see:

• https://github.com/winston/google_visualr/blob/master/lib/google_visualr/base_chart.rb#L55
• https://github.com/winston/google_visualr/blob/master/spec/google_visualr/base_chart_spec.rb

So it could be possible to have the PNG functionality. A convenience helper method can be added to the gem to make that easier too.

However you won't be able to directly use it in your email because most (all?) email clients will not allow JavaScript to run, and hence it's not possible to just use the chart functionality directly in emails.

It will be a two step process where you need to get the URLs manually before putting them in emails.

Hope this answers?

any news? if you could directly turn the chart in PNG, I could add the image to a pdf file ( with Prawn ) or other type of file that does not support javascript

I ended up using Google's deprecated image charts: https://developers.google.com/chart/image/
