So I can easily reset these with the macro call ~@gbt~. The =gbt(col)= function also allows setting grid and border to some other color, but needs to be called using eval, e.g. ~eval(gbt("black"))~. +#+begin_src gnuplot +# grid border tics settings +# call @gbt for defaults +# call eval(gbt("color")) to use color instead of default +gbt(col)=sprintf("set tics nomirror; set border 3 back lc '%s'; set grid back lw 1 lc '%s'",col,col) +gbt="set tics nomirror; set border 3 back lc 'gray50'; set grid back lw 1 lc 'gray50'" +@gbt +#+end_src * Interactive Label Placement [[http://www.gnuplotting.org/interactive-label-placing/][Source]]. I adapted the =label_loop= function to newer gnuplot syntax & added functionality for multiple arguments. The function call to -=label_loop= is stored inside a string and can then be executeds as a -macro like this: src_gnuplot{@iLabel "label1" "label2"}. +=label_loop= is stored inside a string and can then be executed as a +macro like this: ~@iLabel "label1" "label2"~ #+begin_src gnuplot iLabel = "call '~/git/projects/dotfiles/tangle/label_loop.gp " |
