A spotlight on the Google Sheets connector

Written by Richard Heyes, RGraph author, on 23rd July 2018
This article introduces the RGraph connector for Google Sheets and gives you some example code for it. You can read more by viewing the Google Sheets documentation page.

This news article shines a spotlight on the svg Google Sheets connector (there's one for canvas too). Using this you can connect the charts that are displayed on your website directly to a spreadsheet in the online Google Sheets application - without any intervention on your part or having to export it first.

This way you can update a value in your spreadsheet and your website is updated immediately.

Initially, the Google Sheets connector was created for use with RGraph but it's designed so that there are few dependencies - only a few functions in the RGraph core library and for the next release this will be removed from both the canvas and the svg versions of the library.

So if you want to use this connector with your own code then you can - and it's going to be easier as of the next release.
