Question

我似乎无法在matplotlib中获得子图的键间距。我希望x轴上的按键排列到条形图的位置。在某些情节中，y轴上的标记也会以一种奇怪的方式被微调，我似乎无法找到解决方案。以下是为参考而生成的代码和图表。

EX. {'daniel': [#shares, #views, #comments, #likes, #total_engagement]}

def plotUserEngagement():

    keys = top_users.keys()
    f, metrics = plt.subplots(3, 2)

    for graph_data in [(0, 0, 'shares', 0), (0, 1, 'views', 1), (1, 0, 'comments', 2), (1, 1, 'likes', 3), (2, 0, 'Total Engagement', 3)]:
        x = graph_data[0]
        y = graph_data[1]
        engagement_metric = graph_data[2]
        index = graph_data[3]

        graph = metrics[x, y]
        graph.set_title('User ' + engagement_metric)
        user_metric_data = [engagement_by_user[user][index] for user in top_users]
        graph.bar(range(len(top_users)), user_metric_data)
        if [x,y] == [2,0]:
            graph.set_xticklabels(keys, rotation = 'vertical')

    metrics[2,1].set_xticklabels(keys, rotation = 'vertical')
    f.tight_layout()

在上面的示例中，我希望在底部x轴上看到10个用户名，每个10个条线都有一个。我验证了这些键＆＃39;变量实际上包含10个项目。

我有类似的问题在下面的图表中沿着x轴显示表情符号，我期待10个表情符号，每个栏一个： keys = [emoji.decode（＆＃39; utf-8＆＃39;）for top_emojis中的表情符号] f，metrics = plt.subplots（2,2）

def plotEmojiData():
    for graph_data in [(0, 0, 'Appearances', 0), (0, 1, 'Comments', 1), (1, 0, 'Likes', 2)]:
        x = graph_data[0]
        y = graph_data[1]
        emoji_characterictic = graph_data[2]
        index = graph_data[3]

        graph = metrics[x, y]
        graph.set_title('Emoji ' + emoji_characterictic)
        characteristic_data = [top_emojis[emoji][index] for emoji in top_emojis]
        graph.bar(range(len(top_emojis)), characteristic_data)
        graph.set_xticklabels(keys, fontname='symbola', fontsize=20)

plotEmojiData()

engagement_graph = metrics[1, 1]
engagement_graph.set_title('Emoji Total Engagement')
totalEngagement = [appearances[i]+comments[i]+likes[i] for i in range(len(top_emojis))]
engagement_graph.bar(range(len(top_emojis)), totalEngagement)
engagement_graph.set_xticklabels(keys, fontname='symbola', fontsize=20)

f.tight_layout()
plt.show()

如果您希望显示所有标签，则需要明确设置正确的刻度数：

graph.bar(range(len(top_users)), user_metric_data)        
graph.set_xticks(range(len(top_users))  # <<<<<<<<<<<<<<<<<<<<<<<
graph.set_xticklabels(keys, rotation = 'vertical')

子图matplotlib上的x和y轴刻度线间距
