Hi,

I think you can create your own branch, and implement this feature, it should not be very difficult. You can create a merge request for me after you finish, I'd be happy to accept this feature.

Cheers,

- (void)moveRight
   {
if (nil == _dataSource)
{
    NSLog(@"Important!! DataSource Not Set!");
    return;
}
NSInteger index = _rightMostIndex - 5 * DIRECTION;
NSInteger totalColumnsRequired = [_dataSource numberOfColumnsInEColumnChart:self];
NSInteger test = totalColumnsRequired - _rightMostIndex;
NSInteger count = 0;
if (test >= 5) {
    count = 5;
}
else {
    count = test;
    index = totalColumnsRequired-1;
}

EColumnDataModel *eColumnDataModel = [_dataSource eColumnChart:self valueForIndex:index];
if (nil == eColumnDataModel)
    return;
 _leftMostIndex = _leftMostIndex - 5 * DIRECTION;
_rightMostIndex = _rightMostIndex - count * DIRECTION;

//    _leftMostIndex = _leftMostIndex - 5 * DIRECTION;
//    _rightMostIndex = _rightMostIndex - 5 * DIRECTION;


for (int i = 0; i < totalColumnsRequired; i++)
{
    EColumn *eColumn = [_eColumns objectForKey:[NSNumber numberWithInteger:_rightMostIndex + i * DIRECTION]];
    EColumn *nextEColumn = [_eColumns objectForKey:[NSNumber numberWithInteger:_rightMostIndex + (i + 5) * DIRECTION]];
    EColumnChartLabel *eColumnChartLabel = [_eLabels objectForKey:[NSNumber numberWithInteger:_rightMostIndex + i * DIRECTION]];
    EColumnChartLabel *nextEColumnChartLabel = [_eLabels objectForKey:[NSNumber numberWithInteger:_rightMostIndex + (i + 5) * DIRECTION]];


    eColumnChartLabel.frame = nextEColumnChartLabel.frame;
    eColumn.frame = nextEColumn.frame;
    /** Do not inlclude animations at the moment*/
    //        [UIView animateWithDuration:0.5 delay:0 options:UIViewAnimationOptionCurveLinear animations:^{
    //            eColumn.frame = nextEColumn.frame;
    //        } completion:nil];

     }

       [self reloadData];
   }
