中文摘要:

      目的 研究在观察时间受限制的条件下，条形图和圆环图在映射数据占总体比值关系时的优势。方法 实验设计了3种尺寸(占屏幕7.5%，15%，22%)和3种映射取值(1，1/2，1/3)的条形图和圆环图，被测对象对图形映射的数据占比进行判断，以获得2种形态的判断时间均值和错误率均值。实验使用计算机化实验生成系统E-prime收集数据，使用SPSS进行数据统计和分析。结果 映射取值为1、1/2、1/3条件下，条形图的3种尺寸判断时间均值均低于圆环图;条形图判断错误率均值为2.51%，低于圆环图的错误率4.03%;2种图的映射取值越小，判断的速度越慢。结论 条形图的映射判断速度和准确性比圆环图更具有优势，更适合应用于时空受限制的场景，有助于数据可视化设计时减少因数据堆集而导致的信息过载。

英文摘要:

      Under the condition of limited observation time, the advantages of bar graphs and doughnut graphs in mapping data to the overall ratio relationship are studied. The experiment designed bar graphs and doughnut graphs of three sizes (7.5%, 15%, 22% of the screen) and three mapping values (1, 1/2, 1/3), the percentage of data is used for judgment to obtain the average value of the judgment time and the average error rate of the two forms. The experiment uses the computerized experiment generation system E-prime to collect data, and uses SPSS for data statistics and analysis. When the mapping value is 1, 1/2, 1/3, the average value of the judgment time of the three sizes of the bar graph is lower than that of the donut chart; the average judgment error rate of the bar graph is 2.51%, which is lower than that of the donut chart The error rate is 4.03%; the smaller the mapping value of the two graphs, the slower the judgment speed. The speed and accuracy of the mapping judgment of the bar graph is more advantageous than that of the doughnut graph, and it is more suitable for use in time- and space-constrained scenarios, which helps to reduce the information overload caused by data accumulation in the data visualization design.
