地块的多行地块

Question

我想创建一个绘制多行图和最后一行多列图的函数。

    fig = plt.figure()

    ax = plt.subplot(3,1,1)
    ax.plot(self.dfile['test'], label='test', marker='o', markersize=1, linestyle="", zorder=1)
    ax.set_ylabel('test')

    ax1 = plt.subplot(3,1,2)
    qt = self.do_something(self.dfile['foo'])
    ax1.plot(qt, label='foo', marker='x', markersize=1, linestyle="", zorder=1)
    ax1.hlines(y=1,xmin=0, xmax=len(qt),color='r', zorder=2, alpha=0.55, linewidth=0.8)
    ax1.set_ylabel('foobar')
    ax1.set_xlabel('Time (s)')

    ax2 = plt.subplot(3,1,3)
    x = self.dfile['foo'].value_counts().reset_index()

    x1 = self.dfile['foo'][0:150].value_counts().reset_index()
    x2 = self.dfile['foo'][150:300].value_counts().reset_index()
    x3 = self.dfile['foo'][300:450].value_counts().reset_index()
    x4 = self.dfile['foo'][450:600].value_counts().reset_index()

    ax2.scatter(x1['index'], x1['foo'], s=2)
    ax2.set_yticks([0, 10, 20, 30, 40])
    ax2.set_ylabel('Count')
    ax2.set_xlabel('some x label')
    #ax2.grid(linestyle='-', which='both')

    ax3 = plt.subplot(3,2,3)
    ax3.scatter(x2['index'], x2['foo'], s=2)
    ax3.set_yticks([0, 10, 20, 30, 40])
    ax3.set_ylabel('Count')
    ax3.set_xlabel('some x label')

    fig.tight_layout()
    plt.subplots_adjust(wspace=0, hspace=0.15)
    file_name = 'test.png'
    fig.savefig(OUTPUT_PATH + str(file_name), bbox_inches='tight', dpi=DPI, pad_inches=0.1)
    fig.clf()
    plt.close()

这是我的尝试。我要确保最后一行的图多列。 这是一个例子
