HorizontalBarChart X axe labels duplicated

[siyu6974]

After #3114, my labels are duplicated.

Here is my configuration

- (void)viewDidLoad
{
    [super viewDidLoad];
    
    _chartView.fitBars = YES;
    NSArray * values = @[@1,@2,@3,@4,@5,@6,@7,@8];
    labels = [NSMutableArray new];
    [values enumerateObjectsUsingBlock:^(id  _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
        NSString *s = [NSString stringWithFormat:@"entries %@", obj];
        [labels addObject:s];
    }];
    [self setChart:self.chartView withLabels:labels AndValues:values];
}

-(void)setChart:(BarChartView *)barChartView withLabels:(NSArray *)labels AndValues:(NSArray *)values{
    
    NSUInteger count = [labels count];
    double barWidth = 7.0;
    double spaceForBar = 10.0;

    ChartXAxis *xAxis = barChartView.xAxis;
    xAxis.labelCount = count;
    xAxis.valueFormatter = self;
    
    NSMutableArray *dataEntries = [[NSMutableArray alloc] init];
    for (int i = 0; i < count; i++)
    {
        NSNumber *value = [values objectAtIndex:i];
        BarChartDataEntry *dataEntry = [[BarChartDataEntry alloc] initWithX:i*spaceForBar y:[value doubleValue]];
        [dataEntries addObject:dataEntry];
    }
    
    BarChartDataSet *chartDataSet = [[BarChartDataSet alloc] initWithValues:dataEntries];
    
    BarChartData *chartData = [[BarChartData alloc] initWithDataSets:@[chartDataSet]];
    chartData.barWidth = barWidth;
    [chartData setValueFont:[UIFont systemFontOfSize:9.f]];
    
    barChartView.data = chartData;
    [barChartView setScaleMinima:1.f scaleY:count/4.0];
}

- (NSString *)stringForValue:(double)value axis:(ChartAxisBase *)axis
{
    return labels[(int)value /10];
}

Some remarks:

• If there are less than 7 entries, the problem wouldn't occur
• Undo Fixed using wrong axis (Issue #2257) #3114 "fix" the problem
• Delete xAxis.labelCount = count; "fix" the problem

add

xAxis.granularity = 1

@thierryH91200 It does not work. In fact I believe 1 is the default value for xAxis.granularity.
However change it to 10 (spaceForBar) fix the problem!
