常見例句Stacked bar charts are therefore an alternative representation for quantitative multiset data. 堆疊柱形圖應(yīng)此可以是多集數(shù)據(jù)的替代表現(xiàn)形式。Use a multiset bar chart to display various datasets of quantitative data items within one diagram. 在一個圖表中使用多重柱形圖來顯示不用的數(shù)量數(shù)據(jù)集。Multiset bar charts allow the user to compare the magnitude of data items by two separate discrete parameters. 多重柱形圖允許用戶比較兩個不同部分的重要數(shù)據(jù)。For multimap and multiset the process is more complicated: the element may be present many times. 但對于multimap或multiset,該過程就復(fù)雜多了:某鍵對應(yīng)的元素可能出現(xiàn)多次。As a result, when a multimap or multiset has multiple instances of a given key, those instances will be adjacent elements within the container. 因此,在multimap和multiset容器中,如果某個鍵對應(yīng)多個實例,則這些實例在容器中將相鄰存放。std::multiset items(compare); 比較器類型---->具體的比較函數(shù) 返回 multiset
