  • Added MiscPlot object to plot circles, markers and text at lat, lon locations: circle:lat:lon:radius, text:lat:lon:label
  • Changed how plot attributes are managed.  Now there is no default.  So specifying setText( attr, size ) won't set text size if height attribute not set.  You must use setTextHeight explicitly before the setText call to initialize height.  This is the same with marker size.

  • Fixed a bug in GridPlot where parameters not carried over on reinitialization (with panels specifically)
  • Fixed layer specifications in GridPlot so that grids read in properly, functions used right grids and output used proper grids
  • Moved function computations in GridPlot outside of plotting loop. Functions are now done before any plotting which simplifies code and eliminates several bugs
  • Fixed bug in plotting of vector grids in GridPlot.  In some cases, the U and V grids were not properly referenced
  • Added group specification to GridPlot so that it can be used to specify simple labels for complex overlay plots

  • Added resize function to Grids so that grids can expand if needed
  • Fixed issue with constant pointers in IngestFile, MapPlot and Scanp
  • Fixed several options where it now checks for "=" in option setting. This avoids confusion between co= and cod= and between fi= and fill=

Programs
  • Added MiscPlot object to plot and figure programs
  • Added several key resources to input processing by plot and figure
  • Fixed a bug in plot where multiple plots using the same object were literally using the same object.  This meant parameters would not get set because the parameters from the second would override the first.  Now each plot allocated is allocated so that multiple instances of the same object are unique and distinct

New in version 6.60 (August 2009)

Features
  • Added the concept of a value grid.  This is a 1x1 grid used by various functions to represent a constant value grid.  This is mostly used by GridMath to add a value to a grid or scale a grid.

  • Added UpaPlot::setLevel
  • Fixed several bugs in UpaRaw
  • Added UpaRaw::setLevel
  • Added code to UpaTool::decodeTTAA to handle special levels (surface, trop, max wind).  Somehow the indices to these levels were not getting set
  • Fixed a bug in UpaWxpFile where invalid data could corrupt further input reading.  So added a test to skip to end of report if there is a problem
  • Fixed a bug in writing in mandatory level data.  If somehow the data is invalid, it still tries to write it
Includes
  • Added inline functions to Plot to set data type, time sync, date for labeling

New in version 6.59 (June 2009)

Note:  6.58 was an internal release

Features
  • Added new ingest and decoder programs: ingest, sfcdec, mdrdec, rcmdec, upadec
  • Added "sync" parameter to plot objects to target that object as the time and loop sync.  Rather than using the first plottable object, you can specify an object as the time sync with the "sync" parameter.  The base time and loop increment are based on that object.   This is useful for overlaying radar on satellite.   Without sync, the plot would use the latest satellite image and update every 15 minutes.   With sync, the plot will use the latest radar plot and update every 6 minutes.
  • Added quote delimiting to strings parsing.   This means a string won't be broken on "," if a parameter is quoted:

    OLD:   -pa=x,y,va=a,b,c,cod=white
    NEW:  -pa=x,y,"va=a,b,c",cod=white

    In the old version, b,c would be individual parameters and not variable specifications.   With the parameter delimiting, "va=a,b,c" is preserved for variable parsing.
  • To simplify and make consistent the parameter specification, the "plot_param" resource has been replaced with just "parameter".  Most objects have a setParam method and the parameter resource is passed to this method.
  • Some functions were reworked to work on 64 bit platforms.  RHEL5 64 bit versions are now available.

Objects
  • Added buffered decompression in BZlib object (see Buffer object)
  • Added Buffer object for use of buffered data

  • Removed "plot_param" resource and replaced with "parameter"
  • Added Date::fix to zero out missing date elements
  • Added Date::printSeconds

  • Fixed several bugs related to passing missing values to Domain::tran.  This makes sure that if missing values are passed to it, missing values are returned
  • Added getSync to Drawing protoype so that drawings can return whether they are the time sync
  • Reworked time specification in Figure object.  It now only uses file time for base date is current is set to "la" (it would have to then).  Now, for other current specifications, it uses time based on current time
  • Added time sync parameter to Figure so that base date and loop parameters are based on the object with "sync" set and not on the first available object
  • Added buffered read (Buffer object) to File
  • Added FileTool::checkPath which adds a path to a specified filename and checks for existence

  • Added Grid::setLevel, setForeTime and setVar where strings can be passed to set parameters.  This is useful with Perl
  • Added GridCont::initPlot to initialize just the contouring parameters
  • Added check in GridMath::remap to make sure domain is set, otherwise do a null remap (i.e. copy)
  • Fixed several bugs in Hash object related to mulitple keys.  The Hash object had been set up to store all objects entered into it, even duplicates.  This made it difficult to find matching data to update in the hash, such as updating decoded METAR data.  Now only duplicates are saved if at least one of the hash keys is different.
  • Fixed bug in Hash where first item in each table entry was never used
  • Fixed some initialization bugs in ImagePlot
  • Added map specification to ImagePlot so that it can plot a map like other plot objects

  • Reworked NidsFile to use buffered input for decompression.  This fixes several bugs related to the decompression of TDWR data and simplifies the decompression process
  • Changed label of Dbz to dBZ in NidsPlot
  • Changed distance rings in NidsPlot to KM rather than NM.  A new "distm" parameter added to handle rings in NM
  • Changed option in NidsPlot to plot comp reflectivity attribute table to "table" from "graph" (holdover from WXP 5)

New in version 6A37 (June 2006)

In an effort to continue to work on the new object oriented version of WXP.  About 70% of the WXP library is now rewritten in C++.  WXP6 will have a different look and feel in that monolithic programs like sfcwx, rad and grbcalc go away.  WXP6 eliminates the need for wxploop as plotting can be directly scripted.  But WXP6 programs can still plot to a wxploop window for backward compatibility. 

Plotting as objects

WXP6 uses a simple object for plotting, not a monolithic program.  Resources can still be set through a function interface or by using the old resource settings.  Objects are initialized using the WXP resource settings.

Plot and Figure objects

WXP6 has a Plot and Figure object.  Plot is used when a simple plot is needed.  This is ideal for outputing to GIF images.  The Figure object will cause the plot to act more like WXP5 with rescaling, zoom and query capabilities.

Perl and Python interfaces

WXP6 is scriptable using Perl and Python.  This will replace the need for complex scripts like we have today with WXP5.  Objects can be created in these scripting environments and reused.

Low level programming

This will allow the user to access the WXP library and do more with the data. The hope here is to eliminate the problems associated with monolithic programs.  You can read in raw files and plot them how you want them rather than burying the plotting attributes in the raw file.  DatumPlot allows you to add annotation without having to create a raw file.  A new ImagePlot object will allow you to read in images with imbedded projection information and display them.  The MapPlot object will use "mdb" files to plot specific pieces of map data including filled in areas such as specific counties or zones. 

New in version 6.0A18 (February 2005)

GRIB2 additions

Added support for DRS templates 1,2 and 3 to handle NDFD grids.  Added support for DRS template 40 (same as 40000 for Jpeg2000 compression).  Changed the grid type specification for lat-lon grids to be more representative of the actual values.  Added support for Mercator grids.  Added support for "max" and "min" time ranges in GRIB2.

Added support for multiple grids in a single product.  CONDUIT grids put U and V wind in the same GRIB2 product.

Bug Fixes:

  • Fixed GDS lat-lon domain problems for GRIB2.  This allows the use of CONDUIT grids.
  • Fixed bug in forecast time determination for GRIB2.
  • Fixed several bugs in vertical level determination for GRIB2.
  • Fixed redbook file read for LDM data files.  The redbook program improperly read in the WMO header and got into infinite loop. Added check for bad redbook headers to notify user if not a redbook product.
