我正在尝试从 FITS 文件中绘制一些数据,我想知道是否有人知道如何关注绘图轴的某些区域?这是一些示例代码:
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)
我怎么能只从[1.3 to 4]
x 轴绘制区域?
