核心情节：轴标题随机显示，并不总是有效
我试图显示我的 X 和 Y 轴标题，但它们似乎并不总是有效：
CPXYAxisSet *axisSet = (CPXYAxisSet *)graph.axisSet;
CPXYAxis *x = axisSet.xAxis;
x.orthogonalCoordinateDecimal = CPDecimalFromFloat(min);
x.title = [NSString stringWithFormat:@"Distance %@", distLabel];
x.titleLocation = CPDecimalFromFloat(7.5f);
x.titleOffset = 55.0f;
CPXYAxis *y = axisSet.yAxis;
y.orthogonalCoordinateDecimal = CPDecimalFromFloat(minDist);
y.title = @"Altitude";
y.titleOffset = 95.0f;
y.titleLocation = CPDecimalFromFloat(150.0f);
有时 X 标题会显示，但 Y 轴标题永远不会显示。为什么他们不显示？是填充物吗？
plotAreaFrame.paddingLeft = 50;
plotAreaFrame.paddingTop = 10;
plotAreaFrame.paddingRight = 20;
plotAreaFrame.paddingBottom = 50;
I am trying to get my X and Y axis titles to show, but it seems they are not always working:
CPXYAxisSet *axisSet = (CPXYAxisSet *)graph.axisSet;
CPXYAxis *x = axisSet.xAxis;
x.orthogonalCoordinateDecimal = CPDecimalFromFloat(min);
x.title = [NSString stringWithFormat:@"Distance %@", distLabel];
x.titleLocation = CPDecimalFromFloat(7.5f);
x.titleOffset = 55.0f;
CPXYAxis *y = axisSet.yAxis;
y.orthogonalCoordinateDecimal = CPDecimalFromFloat(minDist);
y.title = @"Altitude";
y.titleOffset = 95.0f;
y.titleLocation = CPDecimalFromFloat(150.0f);
Sometimes the X title will show, but the Y axis title NEVER shows. Why are they not showing? Is it the padding?
plotAreaFrame.paddingLeft = 50;
plotAreaFrame.paddingTop = 10;
plotAreaFrame.paddingRight = 20;
plotAreaFrame.paddingBottom = 50;

您需要增加底部和左侧的填充。您的标题偏移量大于两个轴上的偏移量，因此标题被隐藏。
You need to increase your bottom and left padding. Your title offsets are more than that on both axes so the titles are hidden.
