Follow-up Comment #9:

As shown in this gnuplot bug report:

https://sourceforge.net/p/gnuplot/bugs/1135/

I made the following change in Octave:


diff --git a/scripts/plot/util/private/__gnuplot_draw_axes__.m
b/scripts/plot/util/private/__gnuplot_draw_axes__.m
--- a/scripts/plot/util/private/__gnuplot_draw_axes__.m
+++ b/scripts/plot/util/private/__gnuplot_draw_axes__.m

         titlespec{data_idx} = "title \"\"";
         usingclause{data_idx} = sprintf ("binary array=%dx%d scan=yx
origin=(%.15g,%.15g) dx=%.15g dy=%.15g using %s",
             x_dim, y_dim, x_origin, y_origin, dx, dy, format);
-        withclause{data_idx} = sprintf ("with %s;", imagetype);
+        withclause{data_idx} = sprintf ("with %s failsafe;", imagetype);
 
       case "line"
         if (strcmp (obj.linestyle, "none")


In short, adding the keyword "failsafe" to the "with image" command.

This created a much larger svg file without the embedded png file. The svg
image loads fine in eog and firefox.

No idea if this change is safe for all terminals or if logic needs to be added
to apply it only to the svg terminal.
