Question

http://code.google.com/intl/pl/apis/chart/interactive/docs/quick_start.html

Is possible add simply counter to legends?
In this example:

Mushrooms (3)
 Onions (1)
Olives (1)
Zucchini (1)
Pepperoni (2)

Is possible to make? If yes, how?

Answer 1

You can do that easily by including the counter at the end of the legend string. Let’s suppose your values come from an object with a structure such as:

var data = {
    'Mushrooms': 3,
    'Onions': 1,
    'Olives': 1,
    'Zucchini': 1,
    'Pepperoni': 2
}

What you can do is generate a rows array like:

var rows = [];
for (ingredient in data) {
    rows.push([
        ingredient + " (" + data[ingredient] + ")",
        data[ingredient
    ])
}
