I wrote the code to plot and display a simple graph in Python:
import matplotlib.pyplot as plt
import numpy as np
from matplotlib import interactive
interactive(True)
x = np.arange(0,5,0.1)
y = np.sin(x)
plt.plot(x,y)
plt.show
And all I got is a blank screen.
And when I remove the "interactive" thing it shows no error but diplays nothing.
How can I display the graph?
(P.S: I use Python 2.7)
Remove these lines, they are not for a simple graphic:
from matplotlib import interactive
interactive(True)
And you're missing the () in the plt.show()
plt.show()
There is a syntax error. Replace plt.show with plt.show()
Just a note for others for future reference the full code should also include plt.figure() with the interactive elements removed.
Here what I came up with.
import matplotlib.pyplot as plt
import numpy as np
plt.figure()
x = np.arange(0, 5, 0.1)
y = np.sin(x)
plt.plot(x, y)
plt.show()
But this may be a 3.5 problem I've not tried in 2.7
You can also plot graphs with pyformulas.
First pip install pyformulas, then
import pyformulas as pf
import numpy as np
x = np.linspace(-10,10,100)
y = x**2 + x*np.e**(np.cos(x)**2)
pf.plot(x, y)
