如何设置 Coreplot axisLabels 宽度？

Question

我正在处理 axisLabels，需要并排制作标签，中间没有 space。但是，标签似乎已根据文本自动调整大小。有没有办法设置标签的宽度？

CPTXYAxisSet *axisSet         = (CPTXYAxisSet *)self.weightHistoryChart.axisSet;
CPTXYAxis *x                  = axisSet.xAxis;
x.labelingPolicy = CPTAxisLabelingPolicyNone;
NSArray *customTickLocations = [NSArray arrayWithObjects:@1.0, @3.0, @5.0, nil];
NSMutableSet *customLabels   = [NSMutableSet setWithCapacity:3];

for ( NSNumber *tickLocation in customTickLocations ) {

    CPTTextLayer *layer = [[CPTTextLayer alloc] initWithText:@"label"];
    CPTAxisLabel *newLabel = [[CPTAxisLabel alloc] initWithContentLayer:layer];
    newLabel.tickLocation = tickLocation;
    newLabel.offset       = 0;
    [newLabel.contentLayer setBackgroundColor:[UIColor lightGrayColor].CGColor];
    [customLabels addObject:newLabel];
}

x.axisLabels = customLabels;

与space:

删除space:

您可以在 CPTTextLayer 上设置左右填充，以便在文本周围留下额外的 space。但是，如果您只想要标签后面的实心矩形，那么在标签后面添加图层注释可能会更好看。
