xAxis labels are not aligned with grouped bar, when data is more

[Arunarak]

Hi,

I have an issue, xAxis label are not aligned to grouped bar graph when data is more. some labels are missing and everything seems to be fine when zoomed in.
here is my code

chartView.descriptionText =@"";//dic[kJSONChartTitleKey];
// chartView.noDataTextDescription = @"No available data for the chart.";
[chartView setHighlightPerDragEnabled:NO];
chartView.drawBarShadowEnabled = NO;
chartView.drawValueAboveBarEnabled = YES;
chartView.dragEnabled = YES;
// [chartView setScaleEnabled:YES];
// [chartView setScaleXEnabled:YES];
[chartView setScaleYEnabled:YES];
[chartView setDoubleTapToZoomEnabled:YES];
chartView.pinchZoomEnabled = YES;
chartView.drawGridBackgroundEnabled = NO;
chartView.drawBordersEnabled = NO;
chartView.maxVisibleCount = 200;
chartView.fitBars = YES;

        chartView.autoScaleMinMaxEnabled = YES ;
        [chartView setScaleXEnabled:YES];
      
     //   [chartView zoomWithScaleX:5 scaleY:5 x:0.0 y:0.0] ;
        [chartView fitScreen];

ChartXAxis *xAxis = chartView.xAxis;
[xAxis setLabelPosition:XAxisLabelPositionBottom];
xAxis.labelFont = [UIFont systemFontOfSize:10.f];
xAxis.labelTextColor = [UIColor darkGrayColor];
xAxis.drawAxisLineEnabled = YES;
xAxis.drawGridLinesEnabled = NO;
xAxis.drawLimitLinesBehindDataEnabled = YES;

        xAxis.gridLineWidth = .0;
        xAxis.wordWrapEnabled = YES;
        [xAxis setLabelWidth:1.0];
        [xAxis setWordWrapEnabled:YES];
        [xAxis setWordWrapWidthPercent:2.0];
        xAxis.granularityEnabled = true ;
        xAxis.granularity =  1;
       
        xAxis.avoidFirstLastClippingEnabled = YES;
        xAxis.labelCount = labelArray.count;
        xAxis.labelHeight = 3.0;
        xAxis.centerAxisLabelsEnabled = YES;
        xAxis.labelPosition = XAxisLabelPositionBottom ;

        
 
       chartView.xAxis.axisMinimum =  0.0 ;
  
       chartView.xAxis.axisMaximum = self.dataArray.count  ;

NSMutableArray *xVals = [[NSMutableArray alloc] initWithCapacity:labelsArray.count];

        for (int i = 0; i < labelsArray.count; i++){
            [xVals addObject:labelsArray[i % labelsArray.count]];
        }
        
        NSLog(@" xvals %@", xVals) ;
        
        
        
        xAxis.labelCount = labelsArray.count  ;
        
        IntAxisValueFormatter *format = [[IntAxisValueFormatter alloc]init];
        format.xAxisValues = xVals;
        
        
        NSArray * values = [NSArray array];
        
        if (labelsArray.count) {
            values = [NSArray arrayWithArray:priorArray];
        }
        NSArray * currentValues = [NSArray array];
        
        if (labelsArray.count) {
            currentValues = [NSArray arrayWithArray:currentArray];
        }
        
        NSMutableArray *yVals = [[NSMutableArray alloc] initWithCapacity:values.count];
        NSMutableArray *yCurrentVals = [[NSMutableArray alloc] initWithCapacity:currentValues.count];
        
        for (int i = 0; i < values.count; i++)
        {
            NSInteger val1 = [values[i] integerValue];
            [yVals addObject:[[BarChartDataEntry alloc]initWithX:i  y:val1]];
            NSInteger val = [currentValues[i] integerValue];
            
            [yCurrentVals addObject:[[BarChartDataEntry alloc]initWithX:i  y:val]];

        }
             chartView.xAxis.valueFormatter = format;

    
        BarChartDataSet *set1 ;
        BarChartDataSet *set2 ;
        
      NSMutableArray *dataSets = [[NSMutableArray alloc] init];
        [dataSets addObject:set1];
        [dataSets addObject:set2];
        
        BarChartData *data = [[BarChartData alloc] initWithDataSets:dataSets];

        float groupSpace = 0.3;
        float barSpace = 0.05;
        data.barWidth = 0.3;
        [data groupBarsFromX:0 groupSpace:groupSpace barSpace:barSpace];
   
        chartView.data = data;

I have screenshot too.

1. 
2. 

The first picture is proper and the dataarray is 10.
the second picture doesn't show xAxis label and the data array size is 50+.but if zoom in we could see all the labels.

Please help.

Thank You.

take a look at Chart demos. seems you didn't group bars correctly. the grouped bars width and space sum must be 1.0
