Hi Ben,
I should have data the available at once, as I directly read that array
from a netcdf file. The memory requirement for my data is small comparing
to overhead added once plot creation is started. Fabrice's reply includes
most of what you describe except the remove call part. These changes made
big impact to lower my execution times. Thank you again for your
explanation.
