i need some help here, i need to know how to create an array of string retrieved from an array. i'm using powerplot for graph and it only accept float or string array.

i need to create something something like this dynamically. 

NSString \* sourceData[7] = {@"2", @"1", @"4", @"8", @"14", @"15", @"10"};

Below are my code to find out the numbers in strings.

```
NSInteger drunked = [appDelegate.drinksOnDayArray count];
NSMutableArray * dayArray = [[NSMutableArray alloc] init];
NSMutableArray * sdArray = [[NSMutableArray alloc] init];
//float *sdArray[7];

for (int i=0; i<drunked; i++) {
    DayOfDrinks *drinksOnDay = [appDelegate.drinksOnDayArray objectAtIndex:i];
    NSString * dayString= [NSDate stringForDisplayFromDateForChart:drinksOnDay.dateConsumed];
    [dayArray addObject:dayString];
    NSLog(@"%@",[dayArray objectAtIndex:i]);

    drinksOnDay.isDetailViewHydrated = NO;
    [drinksOnDay hydrateDetailViewData];

    NSString * sdString= [NSString stringWithFormat:@"%@", drinksOnDay.standardDrinks];
    [sdArray addObject:sdString];

    NSString *tempstring;
    NSLog(@"%@",[sdArray objectAtIndex:i]);

}

```

thanks for the help :)
