Hi, I'm using SageMath version 9.3, Release Date: 2021-05-09 If I write in my terminal :

print('hello')
x = var('x')
f(x)= x**2
plot(f,-4,4)
print('hello 2')

The 2 hello are printed and also the graphic in a png. If I write these 5 rows in a file .sage and use 'load' or 'attach', only the 2 hello are printed but no png graphic ... Thanks for your help.

There are two ways to go:

  • use show to make the png display in the default viewer
  • use save to save it to a file

Try with:

plot(f, -4, 4).show()
plot(f, -4, 4).save('plot_square_function.png')
