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 matplotlib import pyplot as plt from matplotlib import pylab from pylab import * #Assuming I have my data in the current directory a = pyfits.getdata('fits1.fits') x = a['data1'] # Lets assume data1 is the column: [0, 1, 1.3, 1.5, 2, 4, 8] y = a['data2'] # And data2 is the column: [0, 0.5, 1, 1.5, 2, 2.5, 3] plt.plot(x,y)
How could I only plot the region from
[1.3 to 4] in the x-axis?
plt.axis() function with your limits.
x(y)min/max are the coordinate limits for both axes.
This question has nothing to do with how you manipulate
pyfits, but simply a matter of adding
to your code before
