以Fermi卫星数据为例对Fits文件的数据处理对fits文件（Fermi卫星数据）处理需要用到python的三个库：astropy、numpy、matplotlib。通过astropy库来打开和查看fits文件，numpy库用来做数组的变换，matplotlib库用来呈现图像。因此在操作前需调用库：import numpy as npimport matplotlib.pyplot a.........

matplotlib库坐标轴的设置1.改变x轴 y轴长度添加标签import matplotlib.pyplot as pltimport numpy as npx = np.linspace(-3,5,100)y1 = 3*x+5y2 = x**2plt.figure(num=6,figsize=(7,7))plt.xlim(-10,10)##ylim用来改变y轴长度pl...

matplotlib库的基本使用import matplotlib.pyplot as pltimport numpy as npx = np.linspace(-1,5,50)y = x**3plt.plot(x,y)plt.show()```pythonimport matplotlib.pyplot as pltimport numpy as npx = np.l...
