Zeros of the derivatives of the Riemann zeta function on the left half plane

The plot shows zeros k of the derivatives $$\zeta^{(k)}(\sigma+it)$$ of the Riemann Zeta function the complex plane. For a table of zeros of $$\zeta^{(k)}$$ on the left half plane see More Zeros of the Derivatives of the Riemann Zeta Function on the Left Half Plane by Ricky Farr and Sebastian Pauli
