摘要
常规统计分析软件在聚类分析谱系图的自动成图上,受算法和成图方式局限,成图质量较低,有时出现偏差,程序可读性和可操作性较差,硬件资源占用率偏高。虽前人对此进行了一定的研究,并提出了链式算法,但缺少成图的实施方法。本文运用模块化的软件设计思想,在链式算法的基础上,以循环迭代方式,改善了样品纵向排序方式,并用顺序归并标记的方法提取了谱系图中各线段的顶点数据,大幅简化了谱系图的绘制。解决了用字符代替线段、并类线头无法置中等问题。使得成图在质量、速度上得到了较大的提升,对硬件资源的占用率也大大降低。
The conventional statistical analysis software is limited in dendrogram of cluster for the arithmetic and drawing style. And the program＇s readability and maneuverability are not good. Meanwhile they cost more hardware resource. Although previous work put forward a new method for improving and proposed the chain＇s algorithmic, it is still lack of operational methods of drawing. Linking with the plotting of the dendrogram by handcraft＇s characteristic we use modularization and reform the sorting style for samples in portrait. Moreover, the data of segment for dendrogram are picked up. It simplifies the drawing of dendrogram greatly, solving the problem that segment is replaced by character, thrums can not be set in middle and so on. Finally it makes drawing perfect, rapid and occupies less hardware resource.
