当您在取消对plt.vlines(hcoord,0,4)的注释时运行代码时,您应该会收到一个异常:
fig = plt.figure()
hcoord = np.arange(0,1,23)
v2=np.datetime64('2019-09-13T03:30')
v1=np.datetime64('2019-09-13T05:40')
# Adding Stations V5 / V3 / SAS5 / SAS3
plt.hlines("GA",v1,v2,"grey","dotted")
plt.hlines("SAS3",v1,v2,"grey","dotted")
plt.hlines("SAS5",v1,v2,"grey","dotted")
plt.hlines("V3",v1,v2,"grey","dotted")
plt.hlines("V5",v1,v2,"grey","dotted")
plt.vlines(hcoord,0,4)
plt.show()
ValueError:视图限制最小值-36865.76180555556小于1,并且
是无效的Matplotlib日期值。如果你通过考试,这种情况经常发生
具有日期时间单位的轴的非日期时间值
用日期时间值替换hcoord
时,工作正常:
fig = plt.figure()
hcoord = np.arange(0,1,23)
v2=np.datetime64('2019-09-13T03:30')
v1=np.datetime64('2019-09-13T05:40')
# Adding Stations V5 / V3 / SAS5 / SAS3
plt.hlines("GA",v1,v2,"grey","dotted")
plt.hlines("SAS3",v1,v2,"grey","dotted")
plt.hlines("SAS5",v1,v2,"grey","dotted")
plt.hlines("V3",v1,v2,"grey","dotted")
plt.hlines("V5",v1,v2,"grey","dotted")
plt.vlines(v2,0,4)
plt.show()
不幸的是,我不明白您试图用
hccord=np.arange(0,1,23)
绘制什么,因为此指令返回[0]
。您必须找出如何以日期时间单位生成正确的hcoord
数组,以获得所需的绘图。您的代码没有任何未注释的调用plt.vlines
。具体来说,当你尝试这样做时会出现什么问题?问题是当我从plt.vlines(hcoord,0,4)中删除#时,我只得到一条垂直线,而水平线消失了。Diziet,你就是那个人!泰:你把我想做的东西修好了吗。我不知道HCOORD的值是什么。如果你的问题被解决了,请考虑点击左边的检查标记来关闭主题。
