I built a survey within Drupal, using webform and some other modules to enhance the webform - like to make it multiple pages.
Now I want to establish a simple report, e.g. to show a bar chart, comparing the added data (from the webform submit) with existing data from the sql database (Benchmark).
So my question is, how is the best way to do so?
I found the following solutions:
- Using a report module (e.g. Forena)
- Using the chart module / google chart api
- Using BIRT
- Using SQL / Php Statements.
