一般会使用循环来添加,例如for x in arange(start, end, step)。 其中arange, 是来自numpy的函数。 这个函数比range好,因为支持float浮点数(range不支持)。 这里展示下上面四种类型的plotting objects的效果,如下 对应代码为 fromvpythonimport*# changed from 3GraphVP.pygraph(align='left', title="gcurve sho...
In addition to IDs, vertex and edges can have attributes such as a name, coordinates for plotting, metadata, and weights. The graph itself can have such attributes too (e.g. a name, which will show in print or :meth:`Graph.summary`). In a sense, every :class:`Graph`, v...
