Split value into percentage with a slider

im new to jQuery and searching a way for doing smthing like this:

I have a value [100] and 5 categorys [apple, banana, kiwi, lemon, orange]

What I want is to have for each category a slide开发者_如何学Pythonr (a line with a point on it you can move)

So every category starts with a value of 20 (100 / 5).

When there is more banana than apple and you "slide" banana to the value of 40 the other values should decrase so I've still the full percentage of 100%.

Anyone knows a plugin or has a handy snippet?

Thx in advance!
