在 Core-Plot 中设置 axisConstraints 崩溃并出现错误 'The orthogonalRange was nil in '
Setting axisConstraints in Core-Plot crashes with error 'The orthogonalRange was nil in '
我正在 Objective-C 中使用 Core-Plot 1.6 开发一个旧应用程序。我在 Y 上有左右轴。我正在尝试向 Right-Y 访问添加标签，但只有当我像这样设置 axisConstraint 属性 时它才会崩溃：
rightY.axisConstraints = [CPTConstraints constraintWithUpperOffset:0];
这是我要执行的操作的完整代码。
CPTXYAxis *rightY = [[CPTXYAxis alloc] init];
// Configure the right y-axis
rightY.labelingPolicy = CPTAxisLabelingPolicyNone;
rightY.title = NSLocalizedStringFromTable(@"Time (Sec)", @"Scores", @"Time in seconds label for scores");
rightY.titleTextStyle = axisTitleStyle;
rightY.titleOffset = 23.0f;
rightY.axisLineStyle = axisLineStyle;
rightY.tickDirection = CPTSignPositive;
rightY.labelingPolicy = CPTAxisLabelingPolicyNone;
rightY.labelOffset = 4.0f;
rightY.majorTickLineStyle = axisLineStyle;
rightY.majorTickLength = -5.0f;
rightY.minorTickLength = -2.5f;
rightY.axisConstraints = [CPTConstraints constraintWithUpperOffset:0];
NSInteger rightMajorIncrement = 1;
NSInteger rightMinorIncrement = 1;
CGFloat rightYMax = 12; // should determine dynamically based on max price
NSMutableSet *rightYLabels = [NSMutableSet set];
NSMutableSet *rightYMajorLocations = [NSMutableSet set];
NSMutableSet *rightYMinorLocations = [NSMutableSet set];
for (NSInteger j = rightMinorIncrement; j <= rightYMax; j += rightMinorIncrement) {
NSUInteger mod = j % rightMajorIncrement;
if (mod == 0) {
CPTAxisLabel *label = [[CPTAxisLabel alloc] initWithText:[NSNumberFormatter localizedStringFromNumber:@(13 - j) numberStyle:NSNumberFormatterNoStyle] textStyle:rightY.labelTextStyle];
NSDecimal rightLocation = CPTDecimalFromInteger(j);
label.tickLocation = rightLocation;
label.offset = 2;
if (label) {
[rightYLabels addObject:label];
}
[rightYMajorLocations addObject:[NSDecimalNumber decimalNumberWithDecimal:rightLocation]];
} else {
[rightYMinorLocations addObject:[NSDecimalNumber decimalNumberWithDecimal:CPTDecimalFromInteger(j)]];
}
}
rightY.axisLabels = rightYLabels;
当我将 rightYLabels 添加到 axisLabels 时，它在上面的行上崩溃了。

缺少的是在分配 axisLabels 之前分配 plotSpace。
所以将这行代码移到标签分配上方解决了这个问题。

if (mod == 0) {
CPTAxisLabel *label = [[CPTAxisLabel alloc] initWithText:[NSNumberFormatter localizedStringFromNumber:@(13 - j) numberStyle:NSNumberFormatterNoStyle] textStyle:rightY.labelTextStyle];
NSDecimal rightLocation = CPTDecimalFromInteger(j);

缺少的是在分配 axisLabels 之前分配 plotSpace。
所以将这行代码移到标签分配上方解决了这个问题。
rightY.plotSpace = rightAxisPlotSpace;
这是上面的完整代码。
CPTXYAxis *rightY = [[CPTXYAxis alloc] init];
// Configure the right y-axis
rightY.labelingPolicy = CPTAxisLabelingPolicyNone;
rightY.title = NSLocalizedStringFromTable(@"Time (Sec)", @"Scores", @"Time in seconds label for scores");
rightY.titleTextStyle = axisTitleStyle;
rightY.titleOffset = 23.0f;
rightY.axisLineStyle = axisLineStyle;
rightY.tickDirection = CPTSignPositive;
rightY.labelingPolicy = CPTAxisLabelingPolicyNone;
rightY.labelOffset = 4.0f;
rightY.majorTickLineStyle = axisLineStyle;
rightY.majorTickLength = -5.0f;
rightY.minorTickLength = -2.5f;
rightY.axisConstraints = [CPTConstraints constraintWithUpperOffset:0];
rightY.plotSpace = rightAxisPlotSpace;
NSInteger rightMajorIncrement = 1;
NSInteger rightMinorIncrement = 1;
CGFloat rightYMax = 12; // should determine dynamically based on max price
NSMutableSet *rightYLabels = [NSMutableSet set];
NSMutableSet *rightYMajorLocations = [NSMutableSet set];
NSMutableSet *rightYMinorLocations = [NSMutableSet set];
for (NSInteger j = rightMinorIncrement; j <= rightYMax; j += rightMinorIncrement) {
NSUInteger mod = j % rightMajorIncrement;
if (mod == 0) {
CPTAxisLabel *label = [[CPTAxisLabel alloc] initWithText:[NSNumberFormatter localizedStringFromNumber:@(13 - j) numberStyle:NSNumberFormatterNoStyle] textStyle:rightY.labelTextStyle];
NSDecimal rightLocation = CPTDecimalFromInteger(j);
label.tickLocation = rightLocation;
label.offset = 2;
if (label) {
[rightYLabels addObject:label];
}
[rightYMajorLocations addObject:[NSDecimalNumber decimalNumberWithDecimal:rightLocation]];
} else {
[rightYMinorLocations addObject:[NSDecimalNumber decimalNumberWithDecimal:CPTDecimalFromInteger(j)]];
}
}
rightY.axisLabels = rightYLabels;
