I'm working on a website interaction tool and wondering if anyone can suggest a good plugin to help me build it.
I have a chart of data. I want the website visitor to choose the answers to two variables (predetermined list or entered value within a range), and then the tool would deliver a single answer based on the location in the chart - where the two variables intersect.
For example: Enter "12" and Choose "Blue" and get the answer 0.45. (from the chart. It's not a mathematical formula, and this is a generic version).
Does anyone have any recommendations for a good plugin that can help me build this kind of tool on my Wordpress site? Or am I stuck just putting a link to an ugly PDF chart?
Thanks in advance for your advice.
