[Nfb-science] Accessibility of plots

[Nathanael T. Wales]

Also, I have interacted with plots using the base data, such as in an Excel 
spreadsheet.  Could the data be exported into an Excel spreadsheet?

The software package my team develops has various GUIs. Some of these are 
used for plotting data, usually in the form of two dimensional scatter plots 
or two dimensional histogram plots. The software has the ability to export 
these plots in popular formats, such as jpeg, png, etc. in some cases users 
are able to interact with the GUIs to eg, select a point or set of points.

I'm curious as to what technologies are available that would allow a blind 
user to examine or interact with such plots and/or how the software might be 
modified to make these plots more accessible.

The basic architecture is a set of C++ libraries with a python interface 
layer in the form of command line UI which can be used to launch to 
aforementioned GUIs. Our software runs on 64 bit MacOS and Linux platforms, 
but not Windows.

Thanks for any info or ideas.
