Autoplot Application (20170617a)
Looking at waveform data from old Explorer wave 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 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.
Mac DMG Release is available.
Bugfixes (2017-06-17 r20939):
- 1766: $(Y,end)$m$(d,delta=10) now works.
- 1836: ArrayDataSet.copy used getBack to get the backing array to determine the class, causing runtime error with new mutability checks.
- 1840: display data made a little less confusing.
- correction of templates in das2streams. Thanks, Chris!
- das2stream reader allows yunits to be missing, just print a warning.
- rte_2052946987: index-out-of-bounds caused by failure to update firstIndex, lastIndex when data is reduced and all data is outside of the visible region. Thanks, Kris!
- 1839: append of two rank zero datasets should be a rank 1 dataset. Thanks, Kristoff!
- 1836: revisit mutability of datasets in Jython scripts.
- rte_1917581137: bug which shows with x2go and Ubuntu Mate. Thanks, Kris!
- Jython putProperty correctly uses the mutable dataset.
- digital renderer allows %E for exponential notation.
- colorbar resize control points allow resize of the vertical direction. Thanks, Ivar!
- rte_0153443069: CSV parser editor GUI would fail with NullPointerException because handling was delegated a sloppy code. Thanks, Mimai!
- drag-n-drop from Thunderbird email "save attachment as" dialog fixed.
- rte_2119934227: put a link in the runtime error popup for OutOfMemory errors.
- rte_1890761962: index out of bounds in "near real time" Time range editor.
- allow different credentials to be used on different paths on the same server.
- 1818: getTimeRange( 1990/12/01, 1month ) would fail the pngwalktool because 1990/13/01 was not normalized (via carry).
- 1833: catch bad path when "orbit:file:///" used where "file:///" should have been used. There was code to trap this exception, but the wrong exception type was thrown. Thanks, Ivar!
- 1698: proper support for bundles in qstreams.
- rte_0110509841: old events scheme check (time,deltaTime,color,str) was broken since last production release v2016a_15. Thanks, Chris!
- 1831: hint that something is wrong when URI is rejected in add plot dialog. Thanks, Ivar!
- 1829: check for null when adapting das2streams.
- file:///.../*.png used in PNG Walk tool would clip off the first two characters of each filename's label.
- rte_0424767770: new code didn't account for path where walkImageSequence would be null. Thanks, Ivar!
- DataPoint comparison of non-time values made no sense, causing some points to disappear.
- 1818: pngwalk of Omni DST vs KP skips each December.
- 0656: cancel press in load example script dialog is correctly handled.
- 0595: sftp is now recognized, fixing Jython listDirectory command.
- Data Point Recorder sorting is disabled while data is loaded from a file, for speed.
- 1825: Data Point Recorder drops points when x-axis is not a time axis.
- 1821,0656: load example script dialog cancel didn't work.
- 1697: A second path resulting in waiting threads when FileSystem simultaneously created by multiple threads. Thanks, Seth!
- 1824: -1e30 is treated as fill in DataPointRecorder, to support files from old Das2 applications. Thanks, Darrelle!
- in das2stream reader, buffer capacity now grows on data packet reads as well as header packets. Thanks, Chris!
- '$Y$m$(d,span=4)/P4D' counts off days consistently. Thanks, Masafumi!
- --enableResponseMonitor command line switch function restored, added to AutoplotServlet. Thanks, Seth!
- jnlp needed Codebase attribute to run without complaint.
- 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!
- small round of findbugs cleanup.
- select time by orbit would pick previous orbit if it overlapped slightly.
- 1820: occasional failures of test033, double checking for valid ticks.
- 1723: Wind waves data then dbAboveBackground showed where VALID_MIN was improperly propogated. Thanks, Masafumi!
- 1559: trim getDataSet calls to the time range requested, when the time axis is not visible.
- debug printing for 1814 accidentally left in production release.
- 597: export to wav can now write files containing timetag mapping, to support Larry's animations.
- IDL/Matlab bridge supports bundles of data (coming from HAPI servers, for example).
- IDL/Matlab bridge can now be used with native Python (SciPy), using Python JPype package.
- fftPower of rank 3 join detects when results can be combined to make simpler rank 2 result.
- reducex supports rank 3 join.
- 1840: display data dialog allows copy points to clipboard.
- decimate function added, which keeps every Nth point.
Less recent features:
- formatting events dataset with colors to qstream uses hex format for RGB color.
- das2Server credentials manager has add method for scripts to insert credentials.
- rfe528: Jemmy codes are moved into Autoplot app from VATesting, so that it's easier for any one to create tests.
- Introduce JythonRefactory which will support old names after path names move around in v2017a.
- add FileSystemUtil.unzipFile.
- DataPointRecorder turn off the sorted property as data is loaded, since it is too slow and presumably sorted already.
- display data mouse module keeps track of which renderer was selected, to facilitate comparisons.
- Add action to write PNGWalk as an animated gif.
- Add tools menu to PNGWalkTool, and action to write PNGWalk to PDF file.
- Add handling for yscans without yTags at all, and those that use yTagInterval as well. Thanks, Chris!
- 573: pngwalk tool now supports zoom on image.
- isEventsList now requires that each endTime be greater than or equal to startTime, and is used in guessRenderType, to support (X,Y)->Z where Z can be ordinal data.
- ASCII table reader is able to read in (X,Y)->Z where Z can be ordinal data.
- ASCII table reader where now has matches clause, for example where=sc.matches('.*A')
- Editor panel has switch to turn off arrow annotations for tab, and to allow tab-is-4-spaces instead of completions popup.
- extent filter (which returns min,max of a dataset) added to filters.
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.
