Hi there,

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.

But I'm not sure what way would be best. Do you have example pages / tutorials?
It would be very nice if someone could give me a hint :)

Kind regards and thank you
Thorsten
