When I see line style is only lines or Billboards with kinetic version ROS. I have many states and I would like to present every state by specific color.

The full code:

#!/usr/bin/env python
import rospy

from nav_msgs.msg import Path
from nav_msgs.msg import Odometry
from geometry_msgs.msg import PoseStamped

path = Path()

def odom_cb(data):
    global path
    # path = Path()
    path.header = data.header
    pose = PoseStamped()
    pose.header = data.header
    pose.pose = data.pose.pose


# odom_sub = rospy.Subscriber('/odom', Odometry, odom_cb) 

odom_sub = rospy.Subscriber('/odom_ekf', Odometry, odom_cb)
path_pub = rospy.Publisher('/path', Path, queue_size=10)

if __name__ == '__main__':

Let me answer what I think you asked:

"Can I use another style for the Path Display than Lines or Billboard?"

No, only those two are implemented. AFAIR, this is the same for melodic and noetic. So you'd need to implement any other visualization yourself.

Please clarify?

Thanks, I understood how to do it but there are some issues because c++, I am not good in c++. So, I skipped it.
