zplot's profile - activity

Thank you very much Lisandra. It worked!

Using sage inside a Python program with PyCharm if I write:

q = sage.all.plot(lambda x: x*x, 1, 10)
q.show()

I get in Python console: "Graphics object consisting of 1 graphics primitive" and the program ends well, but the graphic is not shown. On the other hand if I write:

import matplotlib.pyplot as plt
plt.plot([i*i for i in range(10)])
plt.show()

Graphic is perfectly shown in Plots window inside PyCharm. So matplotlib plots are perfectly shown but sage plots are not.

¿How could I get sage plots using PyCharm?

Thank you.

Thank you very much Lisandra. It worked!

Graphic not shown in PyCharm Using sage inside a Python program with PyCharm if I write: q = sage.all.plot(lambda x: x*

If I define J(x) function as:

def J(x):
    sum = 0
    print(int(log(x)/log(2)))
    for i in range(1, int(log(x)/log(2)) + 1):
        sum = sum + 1 / i * prime_pi(x**(1/i))
    return(N(sum))

when I try to plot it using:

p = plot(J(x), (x, 1, 20))
show(p)

I get the message:

cannot convert log(x)/log(2) to int

but if try J function acting on any float number I get a perfect value like:

sage: J(123.456789)
34.0333333333333

I have tried to replace int by floor but with the same result. Any help to solve the plotting problem will be welcome. Thank you.

Thank you very much, Samuel. It worked perfectly.
