我有一个包含一些事件和我期待的情节和与图表的事件细节注释计数下面的熊猫数据框:诠释优雅与大熊猫情节的文本不重叠

我使用下面的代码绘制数据帧(DF)M: - 日期时间 - 由于数据帧包含重复
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()
指标,注释文本即将在一个重叠的方式:
是否有更好的显示方式?
可能的解决办法: 想想我设法随机化的xytext得到一个确定的值阴谋
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看起来像它带走,特别是如果你使用的是静态值旋转overalapping文本的问题来进行。即使有随机值,它看起来也不太好:'ax.annotate(z [i] +''+'Volume:'+ str(v [i]),(mdates.date2num(x [i]),y textcords ='偏移点',arrowprops = dict(arrowstyle =' - |>''),rotation = randint(4.5,9)* 10)'xytext =(1,1), ' – user3499276
