Python 2.7 修改地物布局后，将suptitle置于居中位置

我有一个包含2x2子地块的图形。顶部和底部子图具有与我锚定到左侧图相同的图例，修改了我的全局地物布局，如下所示：

但我的标题不再居中！我在使用此命令进行所有修改后执行此操作：

f.suptitle('Background Efficiency', fontsize=20)

有人知道如何使它居中吗？我尝试了tight_布局方法，但它修改了所有布局，并没有达到我想要的效果

用于绘制所有内容的函数：

def customplot( plots ):
    i=0
    titles=plots.keys()
    figs={}
    # Create all the figures needed (1 per test efficiency)
    while i<len(plots):
            # Create the figure that will contain 4 subplots
            f, axarr = plt.subplots(2, 2)

            # Get the figures data to plot from the 'plots' dictionary
            mywindow=plots[titles[i]]

            # Get curves names (either 'k' or 'filtering') from the 'mywindow' dictionary
            curves_names=mywindow.keys()
            # Get xaxis varying parameter (either 'ratios' or 'dbsizes') from the 'mywindow' dictionary
            x_names=mywindow[curves_names[0]].keys()

            j=0
            while j<len(curves_names):
                    # Get the data to plot in a single subplot from the 'mywindow' dictionary
                    toplot=mywindow[curves_names[j]]
                    k=0
                    while k<len(x_names):
                            # Get the data of a single curve to plot from the 'toplot' dictionary
                            tosubplot=toplot[x_names[k]]

                            # The previous data is a dictionary containing int keys (curves to draw) and strings (xaxis or fixed parameters). We are saving them
                            ints=list()
                            strings=list()

你能发一封邮件吗？我的代码很大。。。我可以提供打印所有内容的函数，但您肯定可以将问题简化为更改子绘图布局和打印suptitle的代码？我添加了该函数。我有点喜欢python，所以我可能做错了。好吧，我知道你在做什么。也许你可以使用f.subplots\u adjustwspace=x在子地块之间创建空间，而不是手动将右侧的两个子地块向右移动0.08，其中x是你找到的某个数字，为你提供了正确的空间？
