### Autoplot Application (20260630a)

Single-Jar : .jar files can be launched on Windows and Mac, and contain a shell script for launching on Unix computers.
dmg: a self-contained installer for Mac computers.
exe: a self-contained installer for Windows computers.
Built with Install4J multi-platform installer builder and deb and rpm are available as well. Thanks, Install4J!

On 32-bit systems, use the single-jar release and a 32-bit version of Java. These systems will be limited to 1GB of memory. Other Autoplot versions are available for about a year.

Autoplot allows plotting of data from many data sources, including remote CDF files and HAPI servers. Datasets are identified with URIs, and by the URI's extension, data are loaded into one uniform data model. Data are then displayed by determining the rendering method and axis ranges to provide a useful display with interactive axes and mouse actions. The data can then be further processed with other operations like smooth and FFT, and Jython scripting provides a capable programming environment.

This is the Autoplot v2026a branch. This is an update to the production version containing bugfixes and minor new features. Java 8 is required.

Autoplot's development is guided by feedback from those using it. Thanks for your feedback!

Bugfixes (2026-06-24):

- 2856: "Horizontal Interval Average" wasn't removed after Spectrogram→Series, resulting in clutter and memory leak.
- 182: Keep track of data reduction and render error bars to show extent of the data in each pixel column. Thanks, Jaya!
- 182: Das2's SeriesRenderer object "simplifyPaths" switch can be used to disable incorrect simplification with Juno data.
- 2854: Correct where ne logic for CSV and ASCII files. Thanks, Sadie!
- Correct completion of QDataSe<T>.
- 2847: 1D and 2D binAverage routines properly handle edges.
- 2849: properly handle events list in old scheme without cache tag.
- rte_0437651749: Das2Server client code assumed DEPEND_0 was non-null.
- 2819: add tooltip about shift+reset.

Older Bugfixes (2026-06-08):

- 2825: remove strange code which unnecessarily flipped Jupiter image. (Allow the xtags to be monotonic decreasing.) Thanks, Masafumi!
- Jython errors were printed twice to the console.
- 2824: don't print the Jython exception extra times.
- Starting up a bunch of CPUs with run batch could trigger race condition where one would fail. Now the guests wait for the host to finish setting up.
- Add kludge to support public GitLab filesystems on research-git.uiowa.edu. Rewrite much of GitLab support to work properly.
- Detect when two script parameters have the same name, instead of strange and inconsistent behavior.
- TimeParser properly supports $(x;name=band) where the extra map will contain "band"
- Properly handle commas in HAPI CSV quoted strings, as with https://cottagesystems.com/server/esac/hapi/data?start=2001-01-01T00:00:00.000Z&stop=2008-07-01T00:00:00.000Z&dataset=C4_CQ_ASP_CAVEATS
- New code for glob to regex added ^ and $ constraints, which the old implementation did not.

Features:

- 181: DasAxis now allows tickLabeller object to be specified, for drawing custom ticks.
- 2850: formatDataSet/export will make the directory if it doesn't exist.
- 2846: script addTopDecoration and addBottomDecoration allow PlotElements to be used.

Less recent features:

- 2845: completions like p.getController().<T>.
- 873: add full reset which is shift+reset.
- 872: try to keep metadata folders open as focus switches.
- Add File->"Open Local .jy Script..." to menubar.
- Support $s (integer number of seconds since 1970-01-01T00:00Z) in aggregations.
