Vapor not showing time series using NetCDF file

1

I was trying to make a movie on vapor from my time-sequences of magnetic field vectors. I can successfully create 4D (t, x, y, z) Bx, By, Bz vectors in a single netcdf file. But while reading on vapor I see only single (t=0) frame.

Hi Rahul, ~could you post a sample of your data, or email a sample to pearse@ucar.edu~?

Nevermind, I see it. Hang tight.

Hey Rahul, when I issue ncdump -v time test_0_5_compl.nc I see that there are 5 time steps, but the value for each timestep is 0. The time values need to be monotonically increasing and unique. Let me know if that fixes things for you.

Thank you Scott!
Now I can read all images after fixing the time step values.
