Autoplot Application (20170304a)
ACE electron channels data used to verify features.
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 Autoplot2016a 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.
Experimental Mac Release is available.
Bugfixes (2017-03-04 r20460):
- addDataPoint.jy script updated to use DataPointRecorder (not DataPointRecorderNew), and supports keystroke mode.
- log "ImageIO used to create" at less than info, to avoid clutter in server logs.
- rte_1490216564: don't throw runtime error when taskSize is zero, just ignore it.
- 1785: unable to format bundle to CDF. (Append is now handled properly.) Thanks, Kristoff!
- 1789: PngWalkTool correct feedback about writing to writable fs. The code didn't distinguish between Read-Only and Read-Write, and assumed that local filesystems were read-write. Thanks, Sebastian!
- rte_0147649225: fall back after failing to find "field6" in bundleDescriptor, because HAPI metadata was mistaken for Rich ASCII.
- rte 0857617456: Null pointer when selecting time field type but time format column has never been set. Thanks, Shiva!
- corrections to format to .wav gui, which wasn't initialized properly to indicate automatic scaling.
- digitizer DataPointRecorder "new" operation fires dataset update event. Thanks, Kris!
- bugfix: vap+cdaweb:ds=IM_K0_SIE&id=SI_PIXELS had image>THUMBSIZE>50 for the RENDER_TYPE, which Autoplot doesn't support as "image"

- check for vap+internal:data_1,data_2 when switching to mash-up
- 1754: Correctly support http://autoplot.org/data/AMSR_E_L3_SeaIce6km_B06_20070307.hdf.gz

- improvements to command line history.
- DownloadResourceAsTempFile never properly indicated progress, showing progress bar with incorrect position.
- Script panel would ask if you want to reload script when time stamp changed, even if the contents did not change.
- 1754: explicitly close Network connections, and call System.gc while interacting with CDAWeb.
- 1754: cache metadata requests so that the metadata for a given file is only retrieved once every ten seconds.
- 1754: corrections to 301 redirects to support old URLs pointing to CDAWeb.
- 1754: Use https to access CDAWeb. Java 1.8.0r102 is now required to access CDAWeb.

- 995: colorbar with color scatter now appears consistently.
- corrections to labels when X,Y->Z is used. Thanks, Babtiste!
- 1191: restore mousewheel behavior to the secondary mouse module.
- 1769: make sure event things happen on the event thread DataPointRecorder
- rte_1889988765: null pointer path in DataPointRecorder load
- bug 1770, catch the NullPointerException and print it to stderr
- clean up DataPointRecorder new so that it provides all the function of DataPointRecorderNew.
- rte_0809841297: Sebastian noticed this harmless runtime exception, which occurs when the last guy listening to the service was closed.
- don't warn about empty script editor which has been modified.
- Some loggers were still logging at INFO, which shows up in web logs and could cause problems.
- 1765: properly handle carots in URIs. Thanks Ivar!
- 1764: vap+inline GUI with events corrected, so that you can re-enter the GUI.
- 1749: GUI generated supports (kinda) positional parameters

- 1762: add support for URL argument types.
- 1760: remove "here" from rebinning code, which would hang the Mac release with stdout noise. Thanks, Sebastian!
- corrections to scatterRebinner to support more data types.
- 1730: correct code for adding label when slice1=i is used. Thanks, Tami!
- file:///tmp/foo.zip/Chipmunks.wav wouldn't work because wav file wasn't accessed properly within the zip file.

Feedback on the function and quality of this release is greatly appreciated!
