Autoplot Application (20170705c)

Fun with the mash up tool, plotting the left and right channels of a stereo wav file.

Autoplot attempts to allow plotting of data from many data sources, including remote CDF files and OpenDAP servers. Datasets are identified with URIs, and by the URI's extension, data are loaded into the internal data model. Data are then displayed by guessing the rendering method and axis ranges to provide a reasonable, useful view of the data. Data can then be additionally processed with other operations like smooth and FFT, and Jython scripting provides a capable programming environment.

This is the Autoplot2017a branch. This is an update to the production version containing bugfixes and minor new features. Java 7 is now required. Java 8 will be required sometime soon.

Single-jar version, autoplot.jar, can be run without network access and from the command line.

Mac DMG Release is available.

Bugfixes (2017-07-05 r21092):

• 1854: clean up code which relied on file.toString to construct URLs for the NetCDF library, which would break on Windows. Thanks, Kristoff!
• rte020756902: old bug where getAllUnits() once returned array of strings now returns array of units showed with recent refactoring. Thanks George!
• rfe528: old references to org.virbo.autoplot.AutoplotUI were not supported in jumbojar, because there were no direct references to the routine.

• TimeParser ISO8601-deriving code would fail because it dropped the Z.
• DataPointRecorder support for old digitizing files is improved.
• 1823: PNGWalkTool QC needs, including show just QC records. Thanks, Kris and Craig!

This completes the feature set for the new production branch. No major features will be added before branching this version. A production branch will be started in a couple of weeks, and the "Start Autoplot" link at the top of autoplot.org will run this version. Feedback on the function and quality of this release is greatly appreciated!
