| 摘 要： | 归纳和总结了定位统计图表表达的理论,给出了定位统计图表的数学模型,并根据统计图表的坐标系维度对其进行了分类。通过统计图表的定位方式抽象出定位图元的几何类型,并相应给出了定位参数的计算方法。最后程序化地实现了直方图、柱状图、扇形图、饼状图、玫瑰图等基础图表的几何定位和自动构建,极大地提高了定位统计地图的设计水平和制作效率。

| Abstract: | This article summarizes the theory of positioning statistical chart expression and presents the mathematical models, at the same time the classification is carried out according to the dimension of the coordinate system used by the chart. Meanwhile, the geometric types of location shape are abstracted from positioning methods of statistical charts, and the calculation methods of location parameters are given accordingly. Finally, this paper realizes the geometric location and automatic construction of basic figures, such as histogram, bar chart, fan chart, pie chart and rose chart, which greatly improves the design level and production efficiency of positioning statistical map. |
