核心繪圖，自定義標籤和刻度標記

Question

我正在使用核心繪圖alpha版本0.2並生成具有自定義標籤的繪圖。標籤出現在正確的位置，但我沒有刻度線。我已嘗試這些設置的每個組合：

x.majorIntervalLength = [[NSDecimalNumber decimalNumberWithString：@「5」] decimalValue]; x.minorTicksPerInterval = 0; x.majorTickLineStyle = lineStyle; x.minorTickLineStyle = lineStyle; x.axisLineStyle = lineStyle; x.minorTickLength = 5.0f; x.majorTickLength = 7.0f; x.tickDirection = CPSignNegative;

我使用還添加填充，以曲線圖的底部：

graph.plotAreaFrame.paddingBottom = 10.0;

它具有將X軸向上移動的效果，但不會顯示刻度標記。這看起來應該很簡單，在自定義標籤的位置生成一個刻度標記。但我看不出有任何辦法可以做到這一點。

想法？

** * *下面是我使用生成的標籤和刻度線，你需要提供的代碼，沒有運氣*

for (int i = 0; i < [xAxisLabels count]; i++) { 
    NSDictionary * labelDict = [xAxisLabels objectAtIndex:i]; 
    NSString *label=[labelDict valueForKey:@"element"]; 

    NSNumber *offset=[labelDict valueForKey:@"x"]; 

    float location=[offset floatValue]*multiplier; 
    CPAxisLabel *newLabel = [[CPAxisLabel alloc] initWithText: label textStyle:labelStyle]; 
    newLabel.tickLocation = CPDecimalFromFloat(location); 
    newLabel.offset = x.labelOffset + x.majorTickLength; 
    [customTicks addObject:[NSDecimalNumber decimalNumberWithDecimal:CPDecimalFromFloat(location)]]; 
    [customLabels addObject:newLabel]; 
    [newLabel release]; 
} 
x.axisLabels = [NSSet setWithArray:customLabels]; 
[x setMinorTickLocations:[NSSet setWithArray:customTicks]]; 
[x setMajorTickLocations:[NSSet setWithArray:customTicks]]; 
[customTicks release];

隨着CPAxisLabelingPolicyNone勾號位置（minorTickLocations和majorTickLocations）。
