我有一些代码:
#!/usr/bin/env python
import matplotlib
matplotlib.use("Agg")
import matplotlib.pyplot as plt
x = [1,2,3,4,5]
y = [1.2,1.9,3.1,4.2,4.8]
plt.plot(x,y)
plt.xlabel('OX')
plt.ylabel('OY')
plt.savefig('figure1.png')
plt.close()
它给了我那个数字:
正如您所看到的,X轴上的“步长”为0.5,但我想将其设置为1。该怎么做?
当我使用plt.xticks(1)
时,它会给我报错:
Traceback (most recent call last): File "overflow.py", line 13, in <module>
plt.xticks(1) File "/usr/lib/pymodules/python2.6/matplotlib/pyplot.py", line 998, in xticks
locs = ax.set_xticks(args[0]) File "/usr/lib/pymodules/python2.6/matplotlib/axes.py", line 2064, in set_xticks
return self.xaxis.set_ticks(ticks, minor=minor) File "/usr/lib/pymodules/python2.6/matplotlib/axis.py", line 1150, in set_ticks
if len(ticks) > 1: TypeError: object of type 'int' has no len()
我在Ubuntu 10.10上使用Python 2.6.6。
