[LON-CAPA-users] gnuplot and option response

[Stuart Raeburn]

Hi Hon-Kie,

> The figures are not in the right place for the option selections.

I expect you have already resolved this.

Anyway, I found that eliminating the 'align="left"' string from the  
contents of the $gnuplot scalar assigned in the script block resulted  
in alignment of a select box to the left of each dynamically generated  
gnuplot image for each foil, with the foils themselves stacked  
vertically.
