I have some code:
#!/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() And it gives me that figure: my figure
as You can see, the "step" on axis X is 0.5 but I would like to set it to 1. How to make it?
When I use plt.xticks(1) it gives me errors:
Traceback (most recent call last): File "overflow.py", line 13, in 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()
I use Python 2.6.6 on Ubuntu 10.10 ....

To set axes of the scatter plot, use xlim() and ylim() functions. To plot the scatter graph, use scatter() function. To set label at the x-axis, use xlabel() function. To set label at y-axis, use ylabel() function.
To set labels on the x-axis and y-axis, use the plt. xlabel() and plt. ylabel() methods.
plt.xticks([1, 2, 3, 4, 5]) xticks documentation.
