我需要绘制两个独立的列：第一个代表数据，第二个代表时间：
All_packets= df.select("ip_adr_src","asn_val","timestamp")
EB_packets=All_packets.filter("asn_val is not NULL")
EB_packets.show()
plotdf=EB_packets.select("asn_val","timestamp")
我想绘制ans_valgroup by ip_adr_src per time。如果我有 6 ip_adr_src，我希望有 6 条曲线。
+--------------------+---------------------------------+-------------+
| ip_adr_src |asn_val | timestamp|
+--------------------+---------------------------------+-------------+
|14:15:92:cc:00:01...| 707|1539071748441|

|14:15:92:cc:00:00...| 6060|1539071850129|
|14:15:92:cc:00:05...| 6262|1539071855046|
|14:15:92:cc:00:00...| 6969|1539071872523|
|14:15:92:cc:00:07...| 6969|1539071872528|
|14:15:92:cc:00:08...| 7171|1539071877609|
但是，我所有的测试都是错误的，我有这个错误：
Dataframe doesn't have an object `'plot'`
如果你能帮助我，我将不胜感激。
我不确定我是否理解您要绘制哪一列，但我怀疑您需要有关如何绘制的帮助。这就是我如何ans_val针对一列绘制一列timestamp：
import matplotlib.pyplot as plt
y_ans_val = [val.ans_val for val in df.select('ans_val').collect()]
x_ts = [val.timestamp for val in df.select('timestamp').collect()]
plt.plot(x_ts, y_ans_val)
plt.ylabel('ans_val')
plt.xlabel('timestamp')
plt.title('ASN values for time')
plt.legend(['asn_val'], loc='upper left')
plt.show()
如果需要绘制其他列，请plt.plot(x,y)多次调用该命令，并在plt.legend(your_cols, loc='upper left')函数中添加每个名称。
