2. Parts of a Figure 现在,让我们更深入地了解Matplotlib图的组件。 Figures A figure can contain any number ofAxes, but will typically have at least one. The easiest way to create a new figure is with pyplot: fig = plt.figure() # an empty figure with no Axes fig, ax = plt.subplots(...
fignum : None or int or False If *None*, create a new figure window with automatic numbering. If a nonzero integer, draw into the figure with the given number (create it if it does not exist). If 0, use the current axes (or create one if it does not exist). .. note:: Becaus...

Plots in matplotlib reside within a Figure object. You can create a new figure by: importmatplotlib.pyplotaspltfig=plt.figure() plt.figure() has a number of options; notably, figsize will guarantee the figure has a certain size and aspect ratio if saved to disk. ...
使用Matplotlib库进行绘图的第一句话通常为plt.figure(),正如官网所说“Create a new image or activate a existed image.”。 函数原型: matplotlib.pyplot.figure(num=None, figsize=None, dpi=None, facecolor=None, edgecolor=None, frameon=True, FigureClass=<class 'matplotlib.figure.Figure'>, clear=False...
