Support for Drupal 7 is ending on 5 January 2025—it’s time to migrate to Drupal 10! Learn about the many benefits of Drupal 10 and find migration tools in our resource center.
Tested with Views 3 beta 3. For fields values, rendered values from views object, have been used. It makes problem if some numerical fields formatters are turned on (like 'Thousand marker' or 'Place a colon after the label').
January 17 Google visualization API compatibility. Number of numerical chart fields now is 20 instead 5 BUT VIEWS OBJECT COMPATIBILITY WITH PREVIOUS VERSIONS IS NOT PRESERVED!!!
So, use this version for new Drupal installation or if you rely need to visualize more then 5 different variables on the chart. If you updating module you must set Date fields (in the charts which use it - motion chart, Annotated Time Line...) in previous views styles again after update.
Chart in the same language as the website, use json_encoding function to get options from PHP into JavaScript (all options now are in $csa array), some scale options for annotated timelines are implemented (Thanks to Cyberwolf for very useful suggestions).
"Table" and "Treemap" was added but without customization options at the moment.
Version for old Google Visualization API. Motion chart time format option. Fixed some bugs concerning date fields in Motion Chart and Annotated Time Line (thanks to vacilando and Cyberwolf).
