在Python中不反转的热图的y轴

Question

我使用子图形生成4个热图，并且要求y轴反转。我正在使用ax[i].invert_yaxis()，但它似乎没有工作。的代码的一个例子是下面：

everything = [data_y_axis, data_length, data_roundness, data_y_SDev] 
legend = ['title1', 'title2', 'title3', 'title4'] 

fig, ax = plt.subplots(nrows = 1, ncols = 4, sharex = False, sharey = True, figsize = (13,3)) 

ax = ax.flatten() 

for i, v in enumerate(everything): 

    heatmap = ax[i].pcolor(v, cmap=plt.cm.Blues) 

    ax[i].invert_yaxis() 
    ax[i].xaxis.tick_top() 
    ax[i].set_xticks(np.arange(v.shape[1])+0.5, minor=False) 
    ax[i].set_xticklabels(column_labels, minor=False) 
    ax[i].set_yticks(np.arange(v.shape[0])+0.5, minor=False) 
    ax[i].set_yticklabels(row_labels, minor=False, fontproperties = titlefont) 
    ax[i].set_xticklabels(column_labels, minor=False, fontproperties = titlefont) 

    cb = fig.colorbar(heatmap, orientation='horizontal', pad=0.02, ax = ax[i]) 
    cb.set_label(label = legend[i], fontproperties = titlefont) 
    cb.outline.set_linewidth(2) 

在everything的项目只是np.arrays，它们都具有相同的形状（4,6）。

它目前正在生产这样的地图：，应该看起来像这样：。

我做了什么明显错误？

Answer 1

啊哈。我解决了它。我从for循环中删除了ax[i].invert_yaxis()，并将其卡在最后。它现在的作品：

for i, v in enumerate(everything): 

    heatmap = ax[i].pcolor(v, cmap=plt.cm.Blues) 

    ax[i].xaxis.tick_top() 
    ax[i].set_xticks(np.arange(v.shape[1])+0.5, minor=False) 
    ax[i].set_xticklabels(column_labels, minor=False) 
    ax[i].set_yticks(np.arange(v.shape[0])+0.5, minor=False) 
    ax[i].set_yticklabels(row_labels, minor=False, fontproperties = titlefont) 
    ax[i].set_xticklabels(column_labels, minor=False, fontproperties = titlefont) 

    cb = fig.colorbar(heatmap, orientation='horizontal', pad=0.02, ax = ax[i]) 
    cb.set_label(label = legend[i], fontproperties = titlefont) 
    cb.outline.set_linewidth(2) 

ax[0].invert_yaxis()
