Autoplot Application (v2018a_6)

Export to IDLSave now supports rank 2 (spectral) data.

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 Autoplot2018a 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 (2018-06-11 r22512):

• ASCII editor panel would incorrectly set depend0units.
• support for https das2servers. Thanks, Chris!
• 1995: corrections to code which aggregates qstreams containing nominal data.
• 1996: correction to caching code which would fail to unload data from memory to hard disk, causing out-of-memory exceptions.
• rte_0761821100: CDF gui attempts to clarify error message about rank 2 DEPEND_0. Swap description of parameter when X or Y tab is selected.
• drop the render type property when param[:,0] is read.
• minor tweaks to HAPI GUI, to improve transparency.
• output console's click-on URL is too easy to trigger, causing confusion. Make double click.
• GUI logger would get extraneous events because of Autoplot printing thread. Check for these and log with lower verbosity.
• 1994: orbit timerange could not be used as the default timerange in scripts, because it would not recognize the correctly formatted time.
• 1987: remove incorrect warning about width and height parameters used with -v in AutoplotServer.
• AutoplotDataServer hapi-csv response is now properly streamed.
• FormatDataSet properly trims HAPI responses, used by AutoplotDataServer.
• 1861: back off automatic conversion until Jython 2.5 is used, Java 2.2 is too aggressive in using the conversion and old scripts were breaking.
• format to CDF properly supports rank 2 depend 1 and supports rank 4 data.
• HAPI export format properly formats to HAPI 2.0, which requires "Z" in timetags.
• 1871: recent entries of timeranges and operations were lost because of new code that appends the recent file using a move.
• use ISO-8859-1 encoding with Jython output, so that micro symbol paints properly.
• 1988: link command, used all over the place, would always copy Z when link(x,y,Z) was used, wasting tons of space...
• 1989: msec vs ms in testing. Canonical units (e.g. ms) are always displayed.
• "degrees" and "Degrees" are now equivalent.
• 1987: revisit height and width parameters of AutoplotServlet. Thanks, Jon!
• horizontal slicer is now able to "plot above", though there is no way to swap out the label.
• export to HAPI (and AutoplotServlet HAPI output) is properly marked as 2.0.

Older Bugfixes:

• rte_1578811180: "Getting started" dialog was missing image resource since package renamimg. Thanks, Dapit!
• Pngwalk's resizeImage code doesn't resize if the dimensions don't change, which happens often.
• "Run Batch" didn't handle URL-type parameters correctly.
• rte_0176698267: mishandling of URIs in new JythonExtensionDataSource. Thanks, Larry!
• 1984: error in inspecting .vap file would clear the address bar, destroying the scientist's URI.
• rte_0395859275: whoops, new code in branch was never tested for "/home/jbf/<TAB>" where NullPointerException was encountered.
• rfe 545: entries for resourceURI were incorrectly used to create the current directory.
• format to QStream supports events data sets.

Features:

• tweaks to HAPI export, including adding "hapi" in the path and adding documentation to GUI.
• rfe638: export-to-idlsav supports rank 2 data. Thanks, cj2g13!
• tweaks to the static html file created for pngwalks, which improves performance over slow networks.
• logspace function added. Thanks, Kristoff!
• DataServer implemented as servlet to improve performance. Thanks, Bob!
• DataSetBuilder nextRecord supports rank 1 string data.
• clicking on http and https links in the console tab will point the browse (Firefox,etc) to the link.
• Radio JOVE community AJ4CO_RAINBOW colorbar is added, using a subset of its 4096 colors. (4096 color version should be available soon.)
• CSV Data Source supports streaming. AbstractDataSource has "getInputStream" method to support streaming subclasses.
• medianFilter supports rank 2 data, performing the operation on slices of the 1st axis.

Less recent features:

• add units "mjd" (for days since midnight, Nov 17, 1958) as a default for the ascii table data source.
• "overplotOf" added to plot command.
• sps and spd readers have a built-in code in case there is no internet.
• maximum number of bundled datasets allowed is increased to 96 from 50, to include HOPE data. Thanks, Seth!
• jnlp file registers .pngwalk with the desktop.
• QStreams have new "enumerationUnit" tag within packetDescriptor to avoid old kludgey method for encoding nominal datums.
• rfe545: run batch tool shows the success/fail for each task.
• Vertical averager mouse tool has export data function. Thanks, Seth!
• AutoplotUI has getDom() method, to support Jython properties like ap2.dom.timeRange.

Known issues:

• Bugs often have a four-digit ID and can be reviewed with https://sourceforge.net/p/autoplot/bugs/<ID>/.
• Features typically have a three-digit ID and can be reviewed with https://sourceforge.net/p/autoplot/feature-requests/<ID>/.

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:)
• das2servers (vap+das2server:)
• QStreams (.qds), QDataSet on a das2Stream
• Plasma Wave Group das2 Server
• NetCDF files (.nc,.ncml)
• HDF5 files (.h5,.hdf5)
• DODs servers (.dds)
• Cluster Exchange Format files (.cef)
• Fits Format Files
• Images (.jpg, .png, .gif)
• Wav audio files (.wav)

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.
