I have a global air-temperature dataset of netCDF-3 format. When I import it into the DG either by directly dragging or by importing gear, I cannot get the full dataset. As you can see, there is not incomplete showing long, lati and time columns with different lengths, lacking air temperature data.
I have consulted a senior expert, but ze has no way at present. I guess there could be others who experienced this as I did, seeking wise from a broader pool.
Thanks.1 month, 2 weeks ago daniel leathersParticipant
I have the same issue with climate data of any type I have tried. I get long/lat and that is it (and not even all of these points). Looking forward to anyone that might have any ideas.1 month, 2 weeks ago petercreateParticipant
The help party is doing on this. We just wait for that coming out. 🙂1 month ago davidModerator
Just uploaded a new beta with improved netCDF import.
Before the only thing that DataGraph picked up were the 1D arrays and they were imported as columns.
The new version imports 2D and 3D arrays as “flattened” arrays. That is, a 3D array like the one you have is imported as four columns, the x, y, z coordinate followed by the value. So a 73x144x12 array is imported as 4 columns with 126,144 numbers each. This is a fairly small number of rows only about half a million numbers total. The 1D arrays are still imported as columns.
Then you can draw this in the scalar field drawing command and use a mask to implement animations.1 month ago daniel leathersParticipant
Many thanks David! Looking forward to trying the new beta.
Thanks for the work on this and thanks for leting us know it is available.

DG does not work well on chipped netCDF files. Here I tested two more files both were chipped from NASA or NCAR database previously.
Hi David, does it have to use so much CPU power when doing the animation?
Thank you, David. It’s great!1 month ago dgteamModerator
Are these files we can get on-line?
We can profile them to see what is causing the slowness.
