Is there a way to make gnuplot plots from tables as per:
#+PLOT: title:"Grades in Physics and Mathematics" ind:2 deps:(3 4) type:2d with:histograms set:"yrange [0:]" set:"xlabel 'Student'" set:"ylabel 'grades'"
|---+--------+-------------+---------|
| | Grades | Mathematics | Physics |
|---+--------+-------------+---------|
| # | Ben | 9.2 | 9.9 |
| # | Tom | 6.7 | 7.7 |
| # | Tim | 7.5 | 6.7 |
| # | Dean | 8.0 | 7.0 |
...automatically show the image of the plot when you export to HTML?
