Figure 5-4. Plot with grid and tight axes
Other options for plt.axis are given in Table 5-1, the majority of which have to be
passed as a string object.
Table 5-1. Options for plt.axis
Parameter Description
Empty
Returns current axis limits
off
Turns axis lines and labels off
equal
Leads to equal scaling
scaled
Equal scaling via dimension changes
tight
Makes all data visible (tightens limits)
image
Makes all data visible (with data limits)
[xmin, xmax, ymin, ymax]
Sets limits to given ( list of) values
In addition, you can directly set the minimum and maximum values of each axis by using
plt.xlim and plt.ylim. The following code provides an example whose output is shown
in Figure 5-5:
In [ 7 ]: plt.plot(y.cumsum())
plt.grid(True)
plt.xlim(- 1 , 20 )
plt.ylim(np.min(y.cumsum()) - 1 ,
np.max(y.cumsum()) + 1 )
