但如果您绘制自己的图形或文本，则为了避免随意的文本截断，必须查询适当的系统度量。
But if you draw your own graphics and text, the appropriate system metrics must be queried in order to avoid arbitrary text truncation.
通过使用图形方法与数字方法的合并，我们就能够对数据集作出其他的质量度量了。
By using a combination of graphical and numerical methodologies, we are able to make additional qualitative assessments on the dataset.
一种考虑这个问题的办法是，如果你还觉得，二重积分是求体积的话，那这个度量的，就是函数1的图形下的体积。
One way to think about it, if you're really still attached to the idea of double integral as a volume what this measures is the volume below the graph of a function one.
