base on SQL queries?

Hi,

You can’t use SQL queries but you can import data from a spreadsheet, if you want: https://github.com/Codeinwp/visualizer/wiki/How-can-I-populate-data-from-Google-Spreadsheet%3F

And if you’re into code, you can also populate it from dynamic data: https://github.com/Codeinwp/visualizer/wiki/How-can-I-populate-chart-series-and-data-dynamically%3F

Let me know. 🙂

Hardeep
