MultipleBarChart barSpace does not work

[ricpi]

In a group bar, barSpace does not work, two bars overlap.

This is my MultipleBarChart:

This is how my MultipleBarChart set up:

self.detailValuationBarChart.delegate = self;

self.detailValuationBarChart.descriptionText = @"";
self.detailValuationBarChart.drawValueAboveBarEnabled = YES;
self.detailValuationBarChart.rightAxis.enabled = NO;
self.detailValuationBarChart.leftAxis.enabled = NO;
self.detailValuationBarChart.legend.enabled = NO;
self.detailValuationBarChart.gridBackgroundColor = [UIColor whiteColor];
self.detailValuationBarChart.userInteractionEnabled = NO;

ChartYAxis *yAxis = self.detailValuationBarChart.leftAxis;
yAxis.labelTextColor = UIColor.whiteColor;
yAxis.labelPosition = YAxisLabelPositionInsideChart;
yAxis.drawGridLinesEnabled = NO;
yAxis.axisLineColor = UIColor.whiteColor;
yAxis.axisMinimum = 0;

ChartXAxis *xAxis = self.detailValuationBarChart.xAxis;
xAxis.labelPosition = XAxisLabelPositionBottom;
xAxis.labelFont = [UIFont systemFontOfSize:10];
xAxis.drawLabelsEnabled = YES;
xAxis.drawAxisLineEnabled = NO;
xAxis.drawGridLinesEnabled = NO;
xAxis.valueFormatter = self;
xAxis.labelCount = 3;

[self setBarChartData:self.detailValuationModel];

This is how my MultipleBarChart data set:

NSNumberFormatter *pFormatter = [[NSNumberFormatter alloc] init];
pFormatter.numberStyle = NSNumberFormatterPercentStyle;
pFormatter.maximumFractionDigits = 1;
pFormatter.multiplier = @1.f;
pFormatter.percentSymbol = @"万";

float barSpace = 0.06;
float barWidth = 0.25;
float groupSpace = 1 - (2 * barWidth) - (2 * barSpace);

NSMutableArray *yValA = [[NSMutableArray alloc] init];
NSMutableArray *yValB = [[NSMutableArray alloc] init];

for (NSInteger i = 0; i < model.condgradeBValueModel.vBuyResidualValueArr.count; i++) {
    [yValA addObject:[[BarChartDataEntry alloc]
                      initWithX:i
                      y:[model.condgradeBValueModel.vBuyResidualValueArr[i] floatValue]]];
}
for (NSInteger i = 0; i < model.condgradeBValueModel.vSellResidualValueArr.count; i++) {
    [yValB addObject:[[BarChartDataEntry alloc]
                      initWithX:i
                      y:[model.condgradeBValueModel.vSellResidualValueArr[i] floatValue]]];
}

BarChartDataSet *set1 = nil, *set2 = nil;
if (self.detailValuationBarChart.data.dataSetCount > 0)
{
    set1 = (BarChartDataSet *)self.detailValuationBarChart.data.dataSets[0];
    set2 = (BarChartDataSet *)self.detailValuationBarChart.data.dataSets[1];
    set1.values = yValA;
    set2.values = yValB;
    
    BarChartData *data = self.detailValuationBarChart.barData;
    [data setValueFont:[UIFont fontWithName:@"HelveticaNeue-Light" size:12.f]];
    [data setValueFormatter:[[ChartDefaultValueFormatter alloc] initWithFormatter:pFormatter]];
    
    [self.detailValuationBarChart.data notifyDataChanged];
    [self.detailValuationBarChart notifyDataSetChanged];
}
else
{
    set1 = [[BarChartDataSet alloc] initWithValues:yValA label:@"Company A"];
    [set1 setColor:COLOR_RGB(254, 183, 192)];
    
    set2 = [[BarChartDataSet alloc] initWithValues:yValB label:@"Company B"];
    [set2 setColor:COLOR_RGB(182, 215, 253)];
    
    NSMutableArray *dataSets = [[NSMutableArray alloc] init];
    [dataSets addObject:set1];
    [dataSets addObject:set2];
    
    BarChartData *data = [[BarChartData alloc] initWithDataSets:dataSets];
    [data setValueFont:[UIFont fontWithName:@"HelveticaNeue-Light" size:12.f]];
    [data setValueFormatter:[[ChartDefaultValueFormatter alloc] initWithFormatter:pFormatter]];
    data.barWidth = barWidth;
    [data groupWidthWithGroupSpace:groupSpace barSpace:barSpace];
    
    self.detailValuationBarChart.data = data;
}

I can't see screenshot.
check #1801, could solve your issue. Also check out multiple bar chart in ChartsDemo.

@liuxuan30
#1081 is different from my question，my question is two bar overlap, the barSpace does not work.
This is my screenshot:

as I said, I can't see your screenshot. It's broken. Have you checked ChartsDemo and play around?
