有沒有辦法給頂部添加填充\偏移量？看屏幕。數字是裁剪如果LimitLine是在頂部：

我有同樣的問題，很多的搜索想通後也沒有什麼直接的獲得額外空間的方法。這是我如何做的：

//dont start at zero 
yaxis.setStartAtZero(false); 
//look at your dataset and set the min and max values of the y-axis at runtime 
//keep the range with some extra space - as you want 
yaxis.setAxisMinValue(4); 
yaxis.setAxisMaxValue(8); 

代碼不被用作-是：上述4和8是適合我的目的號碼 - 更改值，按您的數據點
