iPhone Tapku Graph, how can I use dates instead on numbers?
<p>I've found Tapku Graph <a href="http://duivesteyn.net/2010/03/07/iphone-sdk-implementing-the-tapku-graph-in-your-application/?utm_source=twitterfeed&amp;utm_medium=twitter" rel="nofollow">http://duivesteyn.net/2010/03/07/iphone-sdk-implementing-the-tapku-graph-in-your-application/?utm_source=twitterfeed&amp;utm_medium=twitter</a></p>

<p>... which looks cool and fairly simple to implement</p>

<pre><code>- (void) thread{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

srand([[NSDate date] timeIntervalSince1970]);

for(int i=0;i&lt;100;i++){
    //int no = rand() % 100 + i;
    int no = 10 + i;
    //I've changed the above value to prove that heres 
    //where you supply your data 
    GraphPoint *gp = [[GraphPoint alloc] initWithID:i value:[NSNumber numberWithFloat:no]];
    [data addObject:gp];
    [gp release];
}
    //Heres where the data is drawn
    - (void) drawXAxisLabelsWithContext:(CGContextRef) context{
</code></pre>

<p>However I'd like to have dates on the horizontal axis instead of numbers...<img src="http://i.stack.imgur.com/vuiQT.png" alt="alt text"></p>

<p>Any ideas?</p>
