WebK is called the upper bound of A. Every number greater than K is also an upper bound of A. A set A ⊂ R is bounded from below if there exists a number k such that. k ≤ x ∀ x ∈ A. k is called the lower bound of A. Every number smaller then k is also a lower bound of A. A set is called a bounded set if it is bounded from above as well as ... Webggplot2 - set lower bound greater than lowest point 由于某种原因，我可以使用的 ggplot2 函数扩展到y轴之外，即使可以获取的最小值为零。因此，在尝试将下限限制为零时，我注意到似乎不能仅设置下限以致省略数据点(显然是预测点)。
