What's coming in the next release of NCL
The next release of NCL will likely be version 6.5.0, as we are going to include the much requested "elseif" construct to go with NCL's "if" and "end if" statements.
We may be announcing another new major feature soon. Stay tuned!
We're hoping for a release date of mid summer 2017.
- New "elseif" statement added
- New resources
- Function and procedure bugs
- Graphics bugs fixed
- Other bugs fixed
New "elseif" statement added
This version will have the long-requested "elseif" statement!
The old way of using "else if" required you to have an "end if" for every "else if" statement:
a = 5 if (a.eq.1) then a = a + 1 else if (a.eq.2) then a = a + 2 else if (a.eq.3) then a = a + 3 else if (a.eq.5) then a = a + 5 else a = -1 end if end if end if end if print("a = " + a)
The new way, with the use of "elseif" (no spaces) looks like this:
a = 5 if (a.eq.1) then a = a + 1 elseif (a.eq.2) then a = a + 2 elseif (a.eq.3) then a = a + 3 elseif (a.eq.5) then a = a + 5 else a = -1 end if print("a = " + a)
The old way will still work, and both codes above should return:
a = 10
- gsnShadeFillDotSizeF - allows you to
set the dot size if you are using stippling fill when
- gsnShadeFillScaleF / gsnShadeFillScales - allows you to set
the fill scales for pattern fill when
See example "wavelet_3.ncl" on the Contour effects page.
Functions and procedures bugs fixed
- bin_avg - This function expects equal grid spacing for the destination grid. The internal test required exact spacing. However, some grid spacing led to round-off errors which caused the test to fail. More robust testing was used to address this issue.
Graphics bugs fixed
- Fixed a bug that caused
the cnLineLabelFormat resource to
not be recognized by the gsn_csm contouring routines.
- Fixed a bug where if you are adding a different number of X and Y
reference lines to a plot via
the gsnYRefLine and
gsnXRefLine resources, then you may have
gotten a fatal error:
fatal:Number of dimensions on right hand side do not match number of dimension in left hand side fatal:["Execute.c":8640]:Execute: Error occurred at or near line 6014 in file /usr/local/lib/ncarg/nclscripts/csm/gsn_csm.ncl
If you need a fix for this problem, download this gsn_csm_640_fix.ncl file and load it from your own script after any other load commands.
- Fixed a bug where if you are running a script that calls
gsn_panel to panel XY
plots and setting gsnPanelLabelBar
to True, then you would get a fatal error:
fatal:Variable (mono_fill_scl) is undefined fatal:["Execute.c":8640]:Execute: Error occurred at or near line 6100 \ in file $NCARG_ROOT/lib/ncarg/nclscripts/csm/gsn_code.ncl
The gsnPanelLabelBar resource cannot be applied to XY plots anyway, so the solution is to simply not set this resource. In the next release, NCL will produce a warning instead of exiting with an error.
Other bugs fixed
was not working properly if you give it more than two files.
This bug has been fixed. If you need the fix now, you can download this
new version of ncl_convert2nc.
