我有一個包含一些事件和我期待的情節和與圖表的事件細節註釋計數下面的熊貓數據框:詮釋優雅與大熊貓情節的文本不重疊

我使用下面的代碼繪製數據幀(DF)M: - 日期時間 - 由於數據幀包含重複
import matplotlib.pyplot as plt
import matplotlib.dates as mdates
temp=df[df['Count'].notnull()]
#temp=temp[temp['Importance']=="High"]
x = temp.index
y = temp.Count
z = temp.Event
g = temp.Importance
v = temp.Volume
fig, ax = plt.subplots(figsize=(15,8))
ax.plot_date(x, y, linestyle='--')
for i in range(len(x)):
if g[i]=="Medium":
ax.annotate(z[i]+' '+'Volume: '+str(v[i]), (mdates.date2num(x[i]), y[i]), xytext=(15, 15),
textcoords='offset points', arrowprops=dict(arrowstyle='-|>'))
fig.autofmt_xdate()
plt.show()
指標,註釋文本即將在一個重疊的方式:
是否有更好的顯示方式?
可能的解決辦法: 想想我設法隨機化的xytext得到一個確定的值陰謀
ax.annotate(z[i]+' '+'Volume: '+str(v[i]), (mdates.date2num(x[i]), y[i]), xytext=(5+randint(1,50), 5+randint(1,50)),
textcoords='offset points', arrowprops=dict(arrowstyle='-|>'), rotation=0)
does not看起來像它帶走,特別是如果你使用的是靜態值旋轉overalapping文本的問題來進行。即使有隨機值,它看起來也不太好:'ax.annotate(z [i] +''+'Volume:'+ str(v [i]),(mdates.date2num(x [i]),y textcords ='偏移點',arrowprops = dict(arrowstyle =' - |>''),rotation = randint(4.5,9)* 10)'xytext =(1,1), ' – user3499276
