我有2門陣列這樣matplotlib散射陣列長度不相同
x_test = [[ 14. 1.] [ 14. 2.] [ 14. 3.] [ 14. 4.] [ 14. 5.] [ 14. 6.] [ 14. 7.] [ 14. 8.] [ 14. 9.] [ 14. 10.] [ 14. 11.] [ 14. 12.]]
y_test = [ 254.7 255.4 476.5 19.5 85.6 352. 238.7 144.8 83.5 278.8 449.6 312.7]
我想這些陣列使用matplotlib顯示散射。
這是我的代碼
plt.scatter(x_test, y_test, color='black')
plt.plot(x_test, y_predict, color='blue', linewidth=3)
plt.xticks(())
plt.yticks(())
plt.show()
,這讓我這個錯誤
Traceback (most recent call last):
File "C:\wamp\www\python\test1.py", line 84, in <module>
plt.scatter(x_test, y_test, color='black')
File "C:\Python34\lib\site-packages\matplotlib\pyplot.py", line 3251, in scatter

raise ValueError("x and y must be the same size")
ValueError: x and y must be the same size
兩個數組的長度是相同的,我不明白這是問題。請幫我謝謝
這是我y_predict陣列
y_predict = [ 91.76428571 103.1 86.85714286 401.44642857 339.69642857
196.83571429 126.38928571 31.41071429 211.67857143 167.35357143
288.53214286 107.36785714]
感謝兄弟,它工作正常。 –
