My file format is this which i am using as a trajectory and i have another file with same format which i am using for Refrence , 1716384833.801 0.001 0.001 0.0 0.014 -0.01 0.001 0.029 1716384834.776 0.003 -0.001 0.0 0.019 -0.017 0.001 0.039 1716384835.801 0.003 0.003 0.0 0.013 -0.007 0.002 0.025 1716384836.8 -0.001 0.002 0.0 0.013 -0.007 0.002 0.025 1716384837.799 0.002 -0.001 0.0 0.031 0.005 -0.001 0.062 1716384838.8 -0.033 0.016 0.0 0.009 0.036 -0.045 0.014 1716384839.796 -0.081 0.22 0.0 -0.006 0.058 -0.011 -0.013 1716384840.801 0.08 0.393 0.0 -0.011 0.029 -0.038 -0.025 1716384841.773 0.319 0.379 0.0 -0.007 0.009 -0.133 -0.016 1716384842.799 0.618 0.146 0.0 0.004 0.006 -0.164 0.006,

When i tried to plot the trajectory using this command evo_traj tum trajectory_tum.txt --ref=trajectory_ref.txt -p, i can clearly see the results on 3D Image

But when i use the same command with --plot_mode=xz, Then i can see the results like this Incorrect image

Can you please help me to plot this in xz plane

The data is correctly displayed. Why do you use XZ if your data is in XY?

Thank you for quick reply. i was wondering to visualize it on xz plane, now i got the doubt.
Anyways! i have another question :

  1. if i have different trajectories but i want to plot on a single map, can i do that?

Sure, you can open as many trajectories as you want using evo_traj. See the examples in the README and the Wiki.
