merging arrays

[Bush will disarm all workers next]

I'm new to JavaScript. So please excuse my mistakes.
I need help on merging two arrays into a third one.
There is an array a = {188, 180, 159, 67 }
There is another array b={'Rio de Janeiro', 'Sao Paulo', 'Brasilia',
'Belo Horizonte'}
How can I merge them to produce an array that is equivalent to this:
bg.xValues[0] = [188,'Rio de Janeiro'];
bg.xValues[1] = [180,'Sao Paulo'];
bg.xValues[2] = [159,'Brasilia'];
bg.xValues[3] = [67 ,'Belo Horizonte'];

Thanks
Dakshin

I assume you meant

a = [ 188, 180, 159, 67 ];
b = [ 'Rio de Janeiro', 'Sao Paulo', 'Brasilia', 'Belo Horizonte' ];

Braces ({}) denote object literals, brackets ([]) denote array literals.

bg.xValues[0] = [188,'Rio de Janeiro'];
bg.xValues[1] = [180,'Sao Paulo'];
bg.xValues[2] = [159,'Brasilia'];
bg.xValues[3] = [67 ,'Belo Horizonte'];

function mergeArrays( x, y ) {
var t = [], n = Math.min( x.length, y.length );

for( var i = 0; i < n; ++i ) {
t[ i ] = [ x[ i ], y[ i ]];
}
return t;
}

bg.xValues = mergeArrays( a, b );

If you can guarantee that "a" and "b" will always have the same length,
you can reduce the assignment to "n" to

n = x.length; // or y.length

Hope that helps,
Mike

Thanks for the reply. I tried the code you've posted without success I used
for(i=0; i < a.length; i++)
bg.xValues[i]=[a[i], b[i]];

and also
for(i=0; i < a.length; i++)
bg.xValues[i]=[eval(a[i]), eval(b[i])];

The bg object is a strange beast that expects atomic values like 145 or 'test'.
Any thoughts?

Using eval() certainly won't do any good (there are very few reasons to
*ever* use eval()).

Unless you can point to some documentation that explains what the bg
object is, I haven't got a clue.

Sorry,

Here is the link that has Javascript that uses bg at the bottom of the
page. I've the Graph.js downloaded on another machine. I'll post the
details soon.
