核心情節不顯示標籤（但它顯示的圖形和細軸）

Question

我試圖動用我的OS X應用程序的圖形，我已經成功地繪製圖形和軸：

數據（看趨勢）和y軸蜱似乎是正常的。但是如上所見，任一軸上都沒有標籤，X軸上也沒有刻度。

這裏是我的代碼：

graph = [[CPTXYGraph alloc] initWithFrame:self.mainGraph.bounds]; 
graph.plotAreaFrame.paddingLeft = 50; 
graph.plotAreaFrame.paddingBottom = 60; 
graph.plotAreaFrame.paddingTop = 10; 
graph.plotAreaFrame.paddingRight = 16; 
self.mainGraph.hostedGraph = graph; 
CPTXYPlotSpace *plotSpace = (CPTXYPlotSpace*)graph.defaultPlotSpace; 
NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init]; 
numberFormatter.numberStyle = NSNumberFormatterNoStyle; 
NSTimeInterval oneDay = 60 * 60 * 24; 
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; 
dateFormatter.dateStyle = NSDateFormatterShortStyle; 
CPTTimeFormatter *timeFormatter = [[CPTTimeFormatter alloc] initWithDateFormatter:dateFormatter]; 
timeFormatter.multiplier = @(oneDay); 

NSDate *refDate = [graphDates firstObject]; 
timeFormatter.referenceDate = refDate; 
CPTXYAxisSet *axisSet = (id)graph.axisSet; 
CPTMutableLineStyle *lineStyle = [CPTMutableLineStyle lineStyle]; 
lineStyle.lineColor = [CPTColor grayColor]; 
lineStyle.lineWidth = 1.0f; 

axisSet.yAxis.axisConstraints = [CPTConstraints constraintWithLowerOffset:0]; 
axisSet.yAxis.title = @"Followers"; 
axisSet.yAxis.titleOffset = 0; 
axisSet.yAxis.majorIntervalLength = CPTDecimalFromInt(1000); 
axisSet.yAxis.minorTicksPerInterval = 9; 
axisSet.yAxis.majorTickLineStyle = lineStyle; 
axisSet.yAxis.minorTickLineStyle = lineStyle; 
axisSet.yAxis.minorTickLength = 4; 
axisSet.yAxis.majorTickLength = 10; 
axisSet.yAxis.tickDirection = CPTSignNone; 
axisSet.yAxis.labelFormatter = numberFormatter; 

axisSet.xAxis.axisConstraints = [CPTConstraints constraintWithLowerOffset:0]; 
axisSet.xAxis.majorIntervalLength = CPTDecimalFromInt(oneDay * 7); 
axisSet.xAxis.minorTicksPerInterval = 6; 
axisSet.xAxis.majorTickLineStyle = lineStyle; 
axisSet.xAxis.minorTickLineStyle = lineStyle; 
axisSet.xAxis.labelFormatter = timeFormatter; 
axisSet.xAxis.labelRotation = M_PI/4; 
axisSet.xAxis.majorTickLength = 10; 

我也試過標籤分配政策，但無濟於事（最好我能得到也失去了我的Y軸蜱太）。

且將數據刷新（包括初始負載），這個代碼後：

graphMax = followers * 1.1; 
graphMin = 0; 
CPTXYPlotSpace *plotSpace = (CPTXYPlotSpace*)graph.defaultPlotSpace; 
NSTimeInterval intervalSpan = [[graphDates lastObject] timeIntervalSinceReferenceDate] - [[graphDates firstObject] timeIntervalSinceReferenceDate]; 
plotSpace.xRange = [CPTPlotRange plotRangeWithLocation:CPTDecimalFromDouble(0) length:CPTDecimalFromDouble(intervalSpan)]; 
plotSpace.yRange = [CPTPlotRange plotRangeWithLocation:CPTDecimalFromInt(graphMin) length:CPTDecimalFromInt(graphMax)]; 

凡graphDates保持最小，在一個有序最大的日期，也就是現在分別幾天就回來，只是在我的情況。

我的圖形和我的繪圖區框架在各個方面都有很多填充，所以它似乎不是常見的填充問題。還有什麼導致標籤不顯示？

這個問題是特定於El Capitan和Core Plot的，它由框架解決。
