核心图：增加 x 轴刻度之间的间距？

我有这段代码用于在 x 轴上制作刻度线和标签：

    CPTAxis *x = axisSet.xAxis;
    x.title = @"Hour of Day";
    x.titleTextStyle = axisTitleStyle;
    x.titleOffset = 15.0f;
    x.axisLineStyle = axisLineStyle;
    x.labelingPolicy = CPTAxisLabelingPolicyNone;
    x.labelTextStyle = axisTextStyle;
    x.majorTickLineStyle = axisLineStyle;
    x.majorTickLength = 4.0f;
    x.tickDirection = CPTSignNegative;
    CGFloat dateCount = [timestamps count];
    NSMutableSet *xLabels = [NSMutableSet setWithCapacity:dateCount];
    NSMutableSet *xLocations = [NSMutableSet setWithCapacity:dateCount];
    NSInteger i = 0;
    for (NSString *date in timestampStrings) {
        CPTAxisLabel *label = [[CPTAxisLabel alloc] initWithText:date textStyle:x.labelTextStyle];
        CGFloat location = i++;
        label.tickLocation = CPTDecimalFromCGFloat(location);
        label.offset = x.majorTickLength;
        if (label) {
            [xLabels addObject:label];
            [xLocations addObject:[NSNumber numberWithFloat:location]];
        }
    }
    x.axisLabels = xLabels;
    x.majorTickLocations = xLocations;

我想知道是否可以扩大每个刻度之间的距离，因为现在它看起来就像是一堆压在一起的混乱，与点不对齐。有什么办法可以在每个刻度之间留出更多空间，比如 10 个像素吗？谢谢！

我查了一下，一切都在CGFloat location = i++;。我将其更改为我想要的（5，以像素为单位），如下所示：

CGFloat location = i+=5;

这奏效了。
