import matplotlib.pyplot as plt import sympy as sp import numpy as np q = [3,5] t,i = sp.symbols('t,i') eq = t**2/(q[1]-(t/q[0])**2) x = np.linspace(0,100,10000) y=x**2 plt.plot(x,y)
Now I want to display the sympy equation “eq” on the plot. I have seen many methods to display the same equation using tex commands, but I specifically want to display the sympy eq. Thanks in advance

You could use sympy’s latex()
function like this:
import matplotlib.pyplot as plt import sympy as sp import numpy as np q = [3,5] t,i = sp.symbols('t,i') eq = t**2/(q[1]-(t/q[0])**2) x = np.linspace(0,100,10000) y=x**2 plt.plot(x,y, label=r"$" + f"{sp.latex(eq)}" + r"$") plt.legend() plt.show()
