Question

我想在每次迭代后在一个子图中绘制两个内部循环的结果而不关闭它，这将放在外部循环中，并且在每次外部循环迭代之后，我将保存图。但不幸的是，它只是绘制了每个循环中的最后一组数据。我怎么能设法将它们全部绘制出来？

     shape=['.','s','^']
     colors=['r','b','m','c']    
     for l in range(len(rg)):
        for ii in range(len(ANISO_POLY)):
            for iii in range(len(ST_INT)):
                rc('text', usetex=True)
                rc('font', family='serif')
                fig = plt.figure(figsize=(5,7.5))
                ax = fig.add_subplot(2,1,1)
                ax.set_xscale('log')
                #m, mean_D1, stdev_D1, mean_D2 and stdev_D2 are generated in the inner loop each time
                ax.errorbar(m, mean_D1, yerr=stdev_D1, color=colors[ii], ecolor=colors[ii], fmt=shape[iii], capsize=0, elinewidth=1.0,linestyle='dashed' ,label=ANISO_POLY[ii]+','+ST_INT[iii])
                ax.set_xlabel(r'$\Theta$', fontsize=15)
                ax.set_ylabel(r'$D_1^{+}$', fontsize=15)
                fontsize=10
                for tick in ax.xaxis.get_major_ticks():
                    tick.label1.set_fontsize(fontsize)
                for tick in ax.yaxis.get_major_ticks():
                    tick.label1.set_fontsize(fontsize)            
                ax = fig.add_subplot(2,1,2)
                ax.set_xscale('log')
                ax.errorbar(m, mean_D2, yerr=stdev_D2, color=colors[ii], ecolor=colors[ii], fmt=shape[iii], capsize=0, elinewidth=1.0,linestyle='dashed',label=ANISO_POLY[ii]+','+ST_INT[iii] )
                ax.set_xlabel(r'$\Theta$', fontsize=15)
                ax.set_ylabel(r'$D_2^{+}$', fontsize=15)
                fontsize=10
                for tick in ax.xaxis.get_major_ticks():
                    tick.label1.set_fontsize(fontsize)
                for tick in ax.yaxis.get_major_ticks():
                    tick.label1.set_fontsize(fontsize)
        lg=ax.legend(numpoints=1,loc="upper right", ncol=1,fontsize=8)
        lg.draw_frame(False)
        plotfile='A226_R.ellip'+rg[l]+'.pdf'
        plt.savefig(plotfile, dpi=50, bbox_inches='tight')
        plt.close()

这是我的代码，我不知道我错在哪里!!! ??

如果我尝试保存的每个图形的设置都保留在外部循环中，则图表不会每次更新。

colors = cm.rainbow(np.linspace(0, 1, 12))
for l in range(len(rg)):
    color_count=0
    rc('text', usetex=True)
    rc('font', family='serif')
    fig = plt.figure(figsize=(5,7.5))
    ax1 = fig.add_subplot(2,1,1)
    ax1.set_xscale('log')
    x0,x1 = ax1.get_xlim()
    y0,y1 =ax1.set_ylim(-2e-4,2e-4)
    ax1.set_yticks((-2e-4,-1.5e-4,-1e-4,-0.5e-4,0.0,0.5e-4,1e-4,1.5e-4,2e-4))
    ax1.set_yticklabels([r'$-2\times 10^{-4}$',r'$-1.5\times 10^{-4}$' ,r'$-1\times 10^{-4}$',r'$-0.5\times 10^{-4}$' , r'$0.0$', r'$0.5\times 10^{-4}$',r'$1\times 10^{-4}$',r'$1.5\times 10^{-4}$',r'$2\times 10^{-4}$'])
    ax1.set_xlabel(r'$\Theta$', fontsize=15)
    ax1.set_ylabel(r'$D_1^{+}$', fontsize=15)
    fontsize=10
    for tick in ax1.xaxis.get_major_ticks():
        tick.label1.set_fontsize(fontsize)
    for tick in ax1.yaxis.get_major_ticks():
        tick.label1.set_fontsize(fontsize)            
    ax1.set_aspect((x1-x0)/(y1-y0))
    ax2 = fig.add_subplot(2,1,2, aspect=1)
    ax2.set_xscale('log')
    ax2.set_ylim(-2e-4,4e-4)
    ax2.set_yticks((-2e-4,-1e-4,0.0,1e-4,2e-4,3e-4,4e-4))
    ax2.set_yticklabels([r'$-2\times 10^{-4}$',r'$-1\times 10^{-4}$' , r'$0.0$', r'$1\times 10^{-4}$',r'$2\times 10^{-4}$',r'$3\times 10^{-4}$',r'$4\times 10^{-4}$'])
    ax2.set_xlabel(r'$\Theta$', fontsize=15)
    ax2.set_ylabel(r'$D_2^{+}$', fontsize=15)
    fontsize=10
    for tick in ax2.xaxis.get_major_ticks():
        tick.label1.set_fontsize(fontsize)
    for tick in ax2.yaxis.get_major_ticks():
        tick.label1.set_fontsize(fontsize)
    for ii in range(len(ANISO_POLY)):
        for iii in range(len(ST_INT)):
            ax1.errorbar(m, mean_D1, yerr=stdev_D1, color=colors[color_count], ecolor=colors[color_count], fmt='.', capsize=0, elinewidth=1.0,linestyle='dashed' ,label='Poly. or.:'+ANISO_POLY[ii]+',St. int.:'+ST_INT[iii])
            ax2.errorbar(m, mean_D2, yerr=stdev_D2, color=colors[color_count], ecolor=colors[color_count], fmt='.', capsize=0, elinewidth=1.0,linestyle='dashed',label='Poly. or.:'+ANISO_POLY[ii]+', St. int.:'+ST_INT[iii])
            color_count+=1
    lg=ax2.legend(numpoints=1,loc=4, ncol=3,fontsize=5)
    lg.draw_frame(False)
    plotfile='A226_R.ellip'+rg[l]+'.pdf'
    plt.savefig(plotfile, dpi=50, bbox_inches='tight')
    plt.close()

如何在循环中绘制一组子图并将每个子图保存在外循环中？
