Autoplot release announcement

Autoplot [1] is an interactive browser for data on the web; given a URL of a data file, it tries to create a sensible plot of the contents in the file. Autoplot was developed to allow quick and interactive browsing of scientific data files that are often encountered on the web. Interactive and stylized special views of data that combine data from multiple resources can be saved and shared as bookmarks.

A large suite of bookmarks containing multiple panels using data from many data providers is available by selecting from a list of bookmarks in the Autoplot folder of the Bookmarks menu.

This release introduces three types of bookmarks:

1. Raw - Selecting a raw bookmark will result in an automatic single-panel display of data from a given data provider. (Some GUI interaction may be required for some bookmarks.) Click the right or left arrows to view the day after or day before the day in view.

2. Special Views - Stylized plots using data from many data providers. For examples, see the ViRBO sub-folder. Examples of Data Views include stack plots of measurements from Polar, Cluster, ACE, THEMIS, and NPOES. Data Views are generally created by scientists using the Expert GUI mode and Raw Bookmarks and then contributed to ViRBO's Special Views repository. A tutorial for creating special views will be presented at the Summer 2012 GEM workshop.

3. Overviews - A data set for which the initial view is of the full time range of available data. Draw a box on a time range to zoom in on a specific time interval.

To try Autoplot, click this link, which initiates a ~10-second installation process that works on most operating systems and browsers.

See http://autoplot.org/help#Installation for browser-specific installation hints, http://autoplot.org/help for usage instructions, and send email to http://groups.google.com/group/autoplot for help.

When the installation is complete, browse bookmarks by selecting a bookmark under the Bookmarks menu item (the bookmarks may take a few seconds to appear after Autoplot starts). To see more information about a bookmark, select Bookmarks->Browse and Manage and click the button labeled Detailed Description.

Autoplot was developed under the NASA Virtual Observatories for Heliophysics program in a collaborative effort among several institutions, including support or code contributions from ViRBO, VMO, RBSP-ECT, and the Radio and Plasma Wave Group at The University of Iowa.

## 2.2. Issues

This shows a bug in the cgi script:

but this works

• Jeremy will change so that bookmarks inherit parent folders description-url if one is not specifed.
• Aggregation across zip files does not work. Bug will be fixed.
• ftp://virbo.org/POES/n15/$Y/poes_n15_$Y$m$d.cdf.zip/poes_n15_$Y$m\$d.cdf? results in 550 Failed to change directory error.
• Need some indication for how to un-grey the Data Set selector in basic mode? Or, should data set selector switch you to expert mode? (to discuss)
• 2010-01-01 shows up in Time Range bar (Should say "Select bookmark or File->Add Plot From"?)
