support always refers to the Google help site which is rather useless as you can’t see how the two systems are connecting.
It sounds like you didn’t bother reading the plugin FAQ, which reads:
How do I change the default settings, like can I turn paging off? Can I change the page length? Can I change the sort order?
All of these DataTables options are accessible through shortcode attributes. The shortcode attribute is an underscore-separated version of the DataTables’s CamelCase’ed option name, prefixed with datatables_. For instance, to turn off paging, you need to set the DataTables paging option to false, so you would use a shortcode like this:
[gdoc key=”ABCDEFG” datatables_paging=”false”]
and for charts integration:
How do I customize my chart?
Using specific shortcode attributes, you can choose from a huge number of configurable options to customize the look and feel of your chart. The specific shortcode attributes available to you depend on the type of chart you chose. Refer to the Google Chart API documentation to learn which configuration options are available for which type of charts.
Each configuration option is accessible through a shortcode of a similar name. For instance, the colors configuration option is accessible to you through the chart_colors attribute. It accepts a list of colors, which you supply to the shortcode in a similar way as you might provide a class value:
[godc key=”ABCDEFG” chart=”Pie” chart_colors=”red green”]
Maybe it would be easier for you to use if you, y’know, read that, since that explains exactly “how the two systems are connecting.”
As for documentation lacking configuration examples, there are examples all over the FAQ, the support forum, and each possible attribute is documented in the Other Notes page.
It seems like this thread is mostly just about your issue with negative values going unanswered, which you conveniently omitted from your 1-star “review.” And I gotta say, I’m a lot less motivated to look into your issue now than before.
