我正在绘制 Unix 时间戳与权重,因此我的 x 轴范围例如是:1380330622 到 1382696991
Y轴是:83到86左右...
有40个条目。
我的绘图范围基本上设置为每个的最小值<->最大值,并且图形数据显示得很好......但我根本无法让我的 Axes 出现......
最初,高 x 轴数导致分配大量主要刻度,这已解决,但没有轴:
-(void)configureAxis{
graph.plotAreaFrame.axisSet.borderLineStyle = [CPTLineStyle lineStyle];
// Line styles
CPTMutableLineStyle *axisLineStyle = [CPTMutableLineStyle lineStyle];
