默认左边和底部只有两个轴,我想在右边和底部添加另一个牵引轴,以显示相同的刻度和标签。
提前致谢。
答案 0 :(得分:2)
在制作轴时可以使用约束
CPTXYAxis *x = [self _makeDefaultAxis];
x.coordinate = CPTCoordinateX;
x.axisConstraints = [CPTConstraints constraintWithLowerOffset:0.0];
x.tickDirection = CPTSignPositive;
// ...
CPTXYAxis *y = [self _makeDefaultAxis];
y.coordinate = CPTCoordinateY;
y.axisConstraints = [CPTConstraints constraintWithLowerOffset:0.0];
y.tickDirection = CPTSignPositive;
// ...
CPTXYAxis *y2 = [self _makeDefaultAxis];
y2.coordinate = CPTCoordinateY;
y2.axisConstraints = [CPTConstraints constraintWithUpperOffset:0.0];
y2.tickDirection = CPTSignNegative;
// ...
CPTXYAxis *x2 = [self _makeDefaultAxis];
x2.coordinate = CPTCoordinateX;
x2.axisConstraints = [CPTConstraints constraintWithUpperOffset:0.0];
x2.tickDirection = CPTSignNegative;
这给出了类似的东西,
因此,还要显示调整填充等所需的标签。
