条形图和直方图非常相似,但又有所区别.它们都是用来描述数据的,但侧重点不同:条形图突出各组的具体数据,侧重比较数据之间的差别,而直方图侧重表示各组频数的分布情况,用于判别各组之间的频数的差别.从图表上看,条形图横轴上的数据是孤立的,而直方图上,横轴上的数据是连续的;条形图中,各长方形是分开的,而直方图中,各长方形是靠在一起的. Bar charts are very similar to, but different from, histograms, all of which are used to describe data, but with a different emphasis: bar charts highlight specific data for each group, focusing on comparing differences between the data and histograms Focus on the frequency distribution of each group, used to determine the difference between the frequency of the group.From the chart, the bar chart horizontal axis data is isolated, and the histogram, the horizontal axis of the data is continuous ; Bar chart, the rectangles are separated, and the histogram, the rectangles are together.
