Hi,I am quite new to paraview, I’d like to use paraview for visualizing bathymetry data.  
I have a netCDF file containing the lat, lon, and elevation ,  
Like in this picture, I also want to do this.,

I use the‘Warp by scalar’,  
However, this is not the same as I expected.  
This is the result I got:

This is my nc file：  
[GEBCO\_2019\_131.0\_35.0\_134.0\_32.0.nc](https://www.dropbox.com/s/f6mptbtcqmokj0o/GEBCO_2019_131.0_35.0_134.0_32.0.nc?dl=0)

Can I get the results I expected with my current data?  
I’m sorry for bad English.  
Can you help me understand if this is possible.  
Thanks for the help! 😃

I see two differences:

- color
- surface height

Are there other differences you see?

For the first problem, I recommend following Chapter 2 of the [ParaView Tutorial](https://www.paraview.org/paraview-downloads/download.php?submit=Download&version=v5.7&type=data&os=Sources&downloadFile=ParaViewTutorial-5.7.0.pdf), which addresses how to change the color map and gives you a very thorough understanding of how to use ParaView’s basic features.

For the second problem, adjust the _Scale Factor_ setting in the _Properties Panel_ to make it bigger or smaller.
