Client side dynamic graphing problem

[Nevets Steprock]

I am familiar with application programming, but only started web-programming
a month ago. I want to have a graph on a webpage that the client can click
on and interact with. Specifically, I want the client to see a bar chart
with three bars each representing a different quality (for ease of
explanation, lets say they represent green, red and blue). The client can
put the mouse over one of the bars and increase or decrease its value by
either clicking above the bar or below. I want the bar to change
appropriately without having to have the page refresh each time.

Any ideas where I can get examples or other suggestions would be hugely
appreciated. I don't have much spare coin to buy any programs unless they're
cheap, so free solutions would be best.

Thanks.
Steven

You could do something similar (yet, less complex) to this:

Thanks Robbe,

I had a good look at your site. Not only was the article you pointed out
perfect for the application in mind, but I read some other articles that
were relevant for other aspects of what I'm building.

Respectfully,
Steven
