针对电视剧收视率在播放过程中的影响因素分析需求, 提出一种时空特征可视分析方法. 首先基于热力图映射方法, 展示不同电视剧题材随播出时间变化的收视率时序特征; 并叠加条形图展示相应分类下的收视率均值,用于分类间的对比分析; 然后基于地理位置偏移映射方法, 对电视台的播出量、收视率均值, 以及收视观众人群的性别、年龄、职业分布随地域变化的空间特征进行展示. 以国内具有典型代表性的电视台在2015年3月—2015年12月的收视数据为例进行实验, 结果表明, 该方法能够快速获取不同电视台和电视剧类别在收视率和观众2个方面的对比可视分析, 总结出各目标电视台的差异性特征, 有助于帮助电视台在制作、购买和编排电视剧等方面做出决策.%To analysis the influence factors of the TV drama view ratings, we proposed a visual analytic method for the temporal and spatial feature of broadcasting. Heat map was adopted firstly to show the tem-poral features of the ratings of different TV drama themes. Bar graph was used to compare the average rat-ings of each category. The location offset mapping was introduced to display different TV stations' spatial characteristics such as broadcast volume, average ratings, gender, age and occupational distribution of viewers. We selected the representative TV stations' drama ratings data from March 2015 to December 2015 as an example. The experimental results show that the method can assist efficiently to visual comparison of ratings and viewers for different TV stations and TV drama categories. The method can help making deci-sions in TV drama making, buying and arranging for TV stations.
