### Autoplot Application (20260723a)

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.

Jython scripting "overplotOf" control would keep adding plotElements if reset wasn't called. This bug has been fixed.

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 (2026-07-23):

- 2870: use mapped memory to access data in IDLSave files.
- 2864: correct read of two-element complex array.
- 2827: /tmp/data/data.$s?avail=T properly triggers TimeSeriesBrowse.
- 2860: add escape key to runtime error dialog
- 2863: repeat runs of script without reset and overplotOf would keep adding plot elements. (Code is now enabled)
- 2862: support "print ds[0,-1]" in Jython
- 2864: improve names automatically picked on export to IDLSave.
- incorrect check for fill (Nan==Nan is always false) broke fill value used for times in JUNO/JADE PDS3.
- 2863: repeat runs of script without reset and overplotOf would keep adding plot elements.
- IDLSav of CDF_TT2000 is detected when name contains "epoch". Thanks, Dave!

Older Bugfixes (2026-07-02):

- Completions for IDLSav Y=BSUM_<T> corrected.
- 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.

Features:

- 2867: add routines for realPart and imaginaryPart.
- 877: Allow "https : //..." to be used in the address bar, so that Autoplot URIs are left alone in Outlook.

Less recent features:

- IDLSav of CDF_TT2000 is detected when name contains "epoch". Thanks, Dave!
- 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.
