Sorry I’m fairly new to using these softwares and data formats so I apologize if this is a rather simple question, but I’m importing a .nc file that’s taken at a fixed y-coordinate slice. The dimensions of data variables are [time, x, y, z] with lengths [481, 386, 1, 1152]. When I import it, I make sure not to change any of the scenes or appearance so the bounds of the graph aren’t messed up.

I try adding a render (Contour, not sure if this is the best one but TwoDData is not available) for temperature but nothing shows up. I try checking at different time indices and also have verified there actually is temperature data via the Appearance tab and looking at the distribution.

Hi @ezx, in order to import a .nc file, it needs to be NetCDF-CF complaint. You can find a guide on ensuring you data conforms here: [Non CF-Compliant NetCDF — 3.9.2 documentation](https://ncar.github.io/VaporDocumentationWebsite/dataFormatRequirements/netCDF/nonCompliantNetCDF.html)

One additional note on your data specifically is you appear to have 2D data stored in 3 dimensions with one of the dimensions being one. Vapor supports earth sciences data primarily which would typically store this in [time, x, y]. I would recommend transposing your data so the Z dimension has a length of one and then removing it.
