Autoplot Application (20130328a)

Add ticks from dialog now keeps its own history.

Autoplot attempts to allow plotting of data from many data sources, including local files and OpenDAP servers. Datasets are identified with URIs, and by the URI's extension a module is used to load the data into the internal data model. Data is then displayed by guessing the rendering method and axis ranges to provide a reasonable, useful view of the data.

This is the Autoplot2012b branch. This is an update to the production version containing bugfixes and minor new features. Java 6 is now required.

Single-jar version, autoplot.jar, can be run without network access and from the command line. Note CDFs are only supported via the Java-based reader and Autoplot will attempt to use it when the C-based version is not available.

Bugfixes:

fix problem where save vap before load vap would leave Craig in a strange folder
Leonard pointed out case where CAA would return CDFs that didn't properly mark fill and would cause RTE.
Reiner had RTE caused by URL having "user@" inserted automatically when authorization was needed
Bugfix when output of rank 2 where was used to index dataset.
Non-ascii check in ascii parser didn't account for tabs (ascii=9)
trace function restored when developing jython scripts.
downloadResourceAsTempFile cleanup policy changed to support multiple processes and Tomcat servers
history dialog takes timezone into account when listing today, yesterday, etc
recent change broke BUNDLE in rank 3 datasets from CDF file.
sprocess was called twice when exporting the processed data.
3608830: disable export options that won't work.
rte_1825469520: URL doesn't contain authority (http:///autoplot.org/)
recent history takes current timezone into account when listing today and yesterday's URIs
v2013b_23 had a bug that broke slice1 keyword for C-based reader
status bar at the bottom no longer truncates.
autohistogram/autoranging would fail sometimes with log, picking linear instead.
Larry pointed out that "|hanning(1024)|fftPower(1024)" was briefly broken.
run script dialog would sometimes hang on Windows 7. This is fixed by starting the dialog on the event thread.
3607777: dialogs should be resizable. FilterChainPanel would clip okay button on small displays.
Ascii parser can now handle files with three ISO8601 timetags
Provide a more precise error message when a reference to a plugin is found but plugin is not available.
bugfix: test025 showed where Bx**2 was dropping depend_0 after recent changes.
3606898: completions based on local listings are always displayed along FS completions
reset FS memory caches off of the event thread.
JythonDataSource checks for CancelledOperationException, which shouldn't produce popup.
3607312: improve feedback when ds[0,:] is used on rank 1 dataset
progress monitors and long warning messages were not erased properly for short plots.
minor logging cleaning
small findbugs cleanup
bugfix: annotations for error wouldn't clear when editing
AutoplotDataServer would truncate datasets when an exception was encountered.
wave[DEP0[sec]]*window[] now preserves DEPEND_0
fftPower function now normalizes for window
getFrequencyDomainTags now handles case for FFT of RBSP Mag data where Hz is a better unit than KHz.
rte0014594906: bad format code "v" in completion
preserve log setting when overplotting a linear on log axis when linear data could fit on log
Old versions of Java webstart (1.6u16) would fail to start because of mediawiki improperly reporting fail status.
minor cleanup of PNGWalk tool, add new default bookmarks
turn on tooltips for bookmarks, showing location.
3605590: Java CDF reader no longer holds on to open files, this caused problems, and now we close after 10 seconds.
3606197: NN spectrograms fixed for rank 2 DEPEND_1.
recent changes to Jython eq and ne infix ops broke Jython code like (ds!=None)

Older Bugfixes:

3605224: major ticks don't line up when one axis of stack has labels.
3605415: CDF type "spectrogram>noauto", and user pref for spectrogram
3605230: jython rank zero result of gt ought to be a boolean
3604997: color scatter not connected to colorbar
3604985: CDF DELTA_PLUS/DELTA_MINUS define bins for NN Spectrogram
3604265: partial load of timeseries when scanning around.
3599689: agg sometimes not loading when two on same plot
3604489: double check of isLocal in WebFileSystem results in failure
3603701: Preserve DatumRange types (orbit:...) with built-in axis scan,history
3604777: agg completions missing when tab is pressed in address bar
3587261: white-trace-on-white background is allowed again, because trace on top of spectrogram. A warning is displayed now.

new three-argument |fftPower(512,2,'Hanning') function allows slide and window selection.
add "copy to clipboard" popup menu item to pngwalk tool, so users can easily copy an image to an email.
allow autoplot.emailrte=T in properties to allow emailing RTE from networks that don't allow POST
request processor thread limit is upped to 8 from 6, which was a kludgy fix.
ascii parser has new format spec, e.g. format='f8,i2,i2,i2'
add controls for label and title in ASCII URIs.
record source of scripts installed in tools menu.

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!

Data is input from:

ASCII files (.dat,.txt)
CSV files (.csv)
Binary files (.bin)
CDF files(.cdf)
Excel spread sheets (.xls)
das2Streams (.d2s or .das2Stream)
ViRBO's TSDS server
CDAWeb data server (vap+cdaweb:)

This is not complete, and limitations include:

Quantities of rank 3 dimensionality (e.g. flux(Time,Energy,pitch) are plotted by slicing.
Quantities of rank 4 dimensionality (e.g. flux(Time,Energy,azimuth,sector) are plotted by slicing twice.
