I guess M-x eldoc RET will choke because the first line of a docstring
should shorter.  Other than this nitpick, please feel free to commit,
as you are org-plot.el maintainer.

Thanks

[PATCH] Refresh inline plotted images

[Timothy]

Hi All,

This patch improves the result of running org-plot in the following
situation

#+plot: ... file:"somefile.png"

[[file:somefile.png]]

Previously, when somefile.png is re-plotted the [[file:]] inline image
did not refresh. With this patch, after plotting, overlays of the
replotted image are refreshed.

Subject: [PATCH] org-plot: Refresh inline images after plotting

* lisp/org-plot.el (org-plot/redisplay-img-in-buffer): New function
which searches the current Org buffer for overlays of a certain image,
and refreshes those overlays.
(org-plot/gnuplot): Use `org-plot/redisplay-img-in-buffer' after
plotting to redisplay any associated inline images.
