元组索引在散点图中超出范围
我想散点图一个两列数据看起来如下(打印)
0 0.195871-0.008693j 0.117586+0.001306j
1 0.219024+0.003791j 0.132911-0.007069j
2 0.271063-0.009686j -0.135223+0.007258j
3 0.279217-0.010561j 0.174209-0.004157j
4 0.194862+0.017081j 0.108965+0.007829j
... ... ...
9994 0.398795+0.035182j -0.068538+0.017619j
9995 0.540517+0.059227j -0.250704+0.027940j
9996 0.218166-0.010739j 0.131059-0.008267j
9997 0.285605+0.035444j -0.051080+0.018130j
9998 0.185130+0.009470j 0.113928+0.009426j
[9999 rows x 2 columns]
我不知道上面j是什么意思。无论如何,我写道:
plt.xlabel('LD1')
plt.ylabel('LD2')
plt.scatter(
X_lda.iloc[:,0],
X_lda.iloc[:,1],
c=1,
cmap='rainbow')
但它将:
/usr/local/lib/python3.6/dist-packages/matplotlib/axes/_axes.py in _parse_scatter_color_args(c, edgecolors, kwargs, xshape, yshape, get_next_color_func)
4262 try: # First, does 'c' look suitable for value-mapping?
4263 c_array = np.asanyarray(c, dtype=float)
-> 4264 n_elem = c_array.shape[0]
4265 if c_array.shape in [xshape, yshape]:
4266 c = np.ma.ravel(c_array)
IndexError: tuple index out of range

表格有7列，insert只给了4个值。
insert(self, index, *args) Similar to Tkinter.Listbox.insert(), except that instead of one string a number of strings equal to the number of columns must be given as arguments. It is an error to specify more or fewer arguments than the number of columns. Returns the ID of the newly created item, as returned by item_create().
