Error when running ArmNavigation/rrt_star_seven_joint_arm_control/rrt_star_seven_joint_arm_control.py

When I run ArmNavigation/rrt_star_seven_joint_arm_control/rrt_star_seven_joint_arm_control.py, I get an error:

TypeError: The first argument to axis() must be an iterable of the form [xmin, xmax, ymin, ymax, zmin, zmax]

Seems to be a simple bug with one of the matplotlib functions

I have proposed a fix in: https://github.com/AtsushiSakai/PythonRobotics/pull/1022
