Pyplot Zooming In

I am trying to plot some data from FITS files and I wanted to know if anyone knows how to focus on certain regions of a plot's axis? Here is some example code: import pyfits from m

Solution 1:

Use the plt.axis() function with your limits.

plt.axis([x_min, x_max, y_min, y_max])

where x_min, x_max, y_min, and y_max are the coordinate limits for both axes.

Solution 2:

This question has nothing to do with how you manipulate pyfits, but simply a matter of adding

plt.xlim(1.3, 4.0)

to your code before plt.show()
