Autoplot Application (#{tag})

Access from FTP site works again, where the username and password is only entered once. Images from https://www.wftpserver.com/.

Autoplot allows 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 Autoplot v2020a 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.

Run with 4GB of memory (64-bit Java only): autoplot_4GB.jnlp

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

Mac DMG Release is available.

Bugfixes (2020-10-22 r25232):

• NegativeArraySizeException in intermediate state of SeriesRenderer, when log axis is used and plot has not been sized.
• 2290: unbundle filter GUI contained bug which would insert extra quote in the argument.
• recent change to pngWalkTool didn't consider one of the initialization modes.
• datumRange constructor which took two long-backed cdf_tt2000 datums would convert the end datum unnecessarily, introducing numerical noise.
• correction to FTP so that user:pass is only requested once, anonymous ftp is dropped.
• HAPI server transactions should use UTF-8 and not the system default encoding. Thanks, Vincent and Benjamin!
• Tooltip on progress monitor, which is never truncated, shows transfer rate.
• 2295: improvements to automatic variable name selection.
• improve support for huge CDF files (>2G), by removing a check which assumed that the ByteBuffer was a mapping of the entire file. Improve feedback.
• When PNGWalk has roughly the expected number of files, don't count off intervals, which causes problems when 10-day plots start at year boundaries.
• Yearly update of digital signature for JNLP.
• 2292: bugfix in DataSourceUtil.trimScatterToTimeRange, which didn't find the timetags when three timeseries datasets were bundled. Thanks, Allison!
• 2292: correction to the timerange used in the resultant dataset.
• 2292: mashup tool now puts current list of URIs into the recent URIs, for easier to create URIs of that other datasets from the same file. Thanks, Allison!
• 2292: mashup tool now removes timerange from each URI, which was cluttered and confusing.
• rfe425: in MashUp tool, use new guessNameFor which guarantees unique names.
• rfe425: in MashUp tool, leave tree branch unfolded when inserting an operation, to minimize changes.
• graphical ProgressMonitor shows rate in tooltip as well as the status.
• there was a path where the keychain file would get a file for credentials, not the folder the file is within.
• correction to "show error bars" binding, the initial setting should be disabled.
• bugfix: SerializeDelegate was not added for ErrorBarType
• rte_1611550558: index out of bounds in misformatted time resulted in poor error feedback. Thanks dphartley!
• rte_1611550558: old $x for localized m/d/Y or d.m.Y was leftover in old code, which could be confusing.

Older Bugfixes (2020-09-30 r25152):

• 2289: IOException when TAB is pressed in empty data set selector, instead of discovery of types.
• 2274: Handle redirect to authenticated URL. Thanks, Jon N and Kristoff!
• when loading several datasets from CDF into a bundle, all would have the label of the first. Thanks, Warren!
• rfe694: explicitly handle escape in DataSetSelector, so that it doesn't escape the dialog which contains it.
• 2287: handle case where CDF attribute has String for first value and double array for second and third.
• backgroundThick line (used for contrast) would draw with dashes as well, making it unusable with anything other that solid.
• HapiServerDemo, the Autoplot-based HAPI Server, didn't properly handle fill data.
• 1486: swap plot position doesn't move the empheris data.
• drag and drop file onto canvas works again on the Mac DMG release. Thanks, Allison!
• Use new receiver for RTE reports.
• slice2 and slice3 propagate DELTA_PLUS and DELTA_MINUS properties. Thanks, Mike!
• 2282: ASCII table reader would use enumeration units when the first N records were empty fields, even if numeric data followed. Thanks, Joe!
• ASCII column headers can include granny strings for units, like "N_e(cm!a-3!n)"
• 2278: CDF slice1 keyword didn't work when Epoch16 timetags were used. Thanks, Kristoff!

Features:

• create pngwalk shows processing rate based on last 20 images, not the whole run, so that parallel processing is improved.
• Jython editor has new developer->"Convert Mathematica code to Jython" tool.
• create pngwalk checks for lockfile, so that multiple processes can work on pngwalk in concert.

Less recent features:

• rfe425: Mashup will replace parameter names with the names of datasets, so that the tree is valid.
• export to Das2Stream version 2.3 introduced by Chris.
• experimental ColorSeriesRenderer introduced, which allows color along the line.
• Jython-defined renderers can use colorbar.
• add completions for pattern and format for ASCII data source.
• 728: Allow multiple, non-adjacent columns of ASCII table to be plotted. Thanks, In Sook!
• 725: Create PNGWalk has checkbox will remove images where no data is visible. Thanks, In Sook!
• provide GUI to enable and control error bars, used when data contains DELTA_PLUS and DELTA_MINUS. Thanks, Mike!
• File chooser has types alphabetized and now shows only file-based data sources. Thanks, Allison!
• HAPI data source shows events bar when only timetags are requested, useful for availability.
• suppress the legend when the plot width is less than 100 pixels.

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)

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.
