rlocusplot() does not plot the roots

[lucasmsoares96]

I'm having trouble plotting the root locus diagram. He doesn't show my roots.

$$ X(s) = \frac{6s+204}{s^3+10s^2+34s} $$

using ControlSystems
sys2 = tf(
	[6,204],
	[1,10,34,0]
)
rlocusplot(sys2)

The Julia code above draws the following graph:

But the scilab equivalent shows a root close to -35.

How do I show the hidden root?
