*Hi,

I am trying to plot a 3D surface plot. I have a list of x,y,z values. They are all of different dimensions.

```
y1 y2 y3 y4...
```

x1 z11 z12 z13 z14

x2 z21 z22 z23 ....

x3 .................

x4

x5

.

.

.

etc..*

```
import csv
from mpl_toolkits.mplot3d import Axes3D
from matplotlib import cm
import matplotlib.pyplot as plt
import numpy as np
import datetime as dt
import time
import pylab as p
import mpl_toolkits.mplot3d.axes3d as p3
fname = "C:\Users\Desktop\Temperature.csv"
depth_list = []
tempr_list = []
with open(fname) as fin:
for ix, line in enumerate(fin):
line = line.rstrip()
line_list = line.split(';')
if ix == 0:
time_list = line_list[1:]
else:
depth_list.append(float(line_list[0]))
tempr_list.append([float(t) for t in line_list[1:]])
plt.plot(depth_list, tempr_list)
fig = plt.figure()
ax = fig.gca(projection='3d')
#ax.plot_trisurf(time_list, depth_list, tempr_list, cmap=cm.jet, linewidth=0.2)
plt.show()
timelist = []
for i in range(len(time_list)):
timelist = time.mktime(time.strptime(time_list[i], "%d.%m.%Y %H:%M:%S"))
ax.plot3D(depth_list, tempr_list, timelist)
```

The error I get, I'll just paste the entire thing:

ValueError: setting an array element with a sequence.

I tried converting the timelist to string, but its not working.. Not quite sure what to do:(
