这两个雷达图的橙色位具有相同的数据点,但灰色位的数据点不同。但是,正如您所看到的,它是自动缩放的,并且第二个图表上的橙色位最终会更大,即使它们是完全相同的数据点。有没有办法关闭自动缩放?我也希望 100% 直接到达图表的边缘。

最佳答案
孙博弘的回答是不正确的,但让我意识到解决这个问题是多么容易。这解决了自动缩放问题,现在也达到了边缘。
self.radarChart.yAxis.customAxisMin = 0;
self.radarChart.yAxis.customAxisMax = 1;
关于ios-charts 雷达图关闭自动缩放,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/36432519/
