figures:存放实例代码生成的图片 scripts:存放实例代码 初级绘制 这一节中,我们将从简到繁:先尝试用默认配置在同一张图上绘制正弦和余弦函数图像,然后逐步美化它。 第一步,是取得正弦函数和余弦函数的值: from pylab import * X = np.linspace(-np.pi, np.pi, 256,endpoint=True) C,S = np.cos
→ fig.savefig(”figure.pdf”, transparent=True) … clear a figure? → ax.clear() … close all figures? → plt.close(”all”) … remove ticks? → ax.set_xticks([]) … remove tick labels ? → ax.set_[xy]ticklabels([]) … rotate tick labels ? → ax.set_[xy]ticks(rotation=90...
methods of the Figure class Additionally, theFigureclass provides methods for clearing figures. I'll assume in the following thatfigis an instance of aFigure: fig.clf()clears the entire figure. This call is equivalent toplt.clf()only iffigis the current figure. fig.clear()is a synonym for...

Figures and Subplots fig = plt.figure() 1 ax1 = fig.add_subplot(2,2,1) 1 ax2 = fig.add_subplot(2,2,2) ax3 = fig.add_subplot(2,2,3) fromnumpy.randomimportrandn plt.plot(randn(50).cumsum(),'k--') [<matplotlib.lines.Line2Dat0x28e7668cb38>] ...
You’ll want to explicitly close each of them after use to avoid a MemoryError. By itself, plt.close() closes the current figure, plt.close(num) closes the figure number num, and plt.close('all') closes all the figure windows: Python >>> plt.close('all') >>> get_all_figures(...
ax和fig没有close用法,只有plt.close(),其针对的关闭对象为最后一个figure plt.close(figure_number)# 如果有多个figure,不输入默认关闭最后一个,也可选择关闭某个figure 可能良好的习惯是在show之后close所有的figures plt.show() plt.close("all")
