我正试图在Python中向Matplotlib中的图表添加文本。它没有显示-没有任何错误。

fig = plt.figure(figsize=(12, 8))
ax = fig.add_subplot()
dtFmt = mdates.DateFormatter('%d.%m - %H:%M')
plt.gca().xaxis.set_major_formatter(dtFmt)
plt.grid()
ax.set_ylim(bottom=0, top=df.threadswaiting.max()+10)
ax.plot(df.threadsrunning, label='Running Threads', color='blue')
ax.plot(df.threadswaiting, label='Waiting Threads', color='red')
ax.set_title(f'Thread load\nLast {offset}\ncreated: {timestamp}')
ax.set_ylabel('Threads')
ax.set_xlabel('Time')

# Definition of teststring, which is not showing up:
ax.text(1, 1, 'Teststring')

plt.legend()
plt.show()

有人帮忙吗？谢谢！
Dataframe “df”由以下形式的数据组成：

timestamp,memtotal,memfree,memused,mempercentage,threadsmax,threadsrunning,threadswaiting

现在起作用了。但我还是不明白为什么。

ax.text(0.1, 0.876,
    f'Running Mean: {round(df.threadsrunning.mean(), 2)}\n'
    f'Waiting Mean: {round(df.threadswaiting.mean(), 2)}\n'
    f'Running Max: {round(df.threadsrunning.max(), 2)}\n'
    f'Waiting Max: {round(df.threadswaiting.max(), 2)}',
    bbox=dict(facecolor='white', alpha=0.5), fontsize=12, transform=ax.transAxes)
