## Command to make an exponential basis

define ebasis curve = min : max
   local temp
   basis temp = log($min) : log($max)
   temp = 10^temp
   splice $curve = temp : temp
enddef



## Define an alternate syntax for EBASIS command

define [after] ebasis curve = max   ## [after] = add this defn after old one
   ebasis $curve = 1 : $max         ## Can define the command in terms of
enddef                              ##   a different form it itself!



## Add exponential bases as an option to normal BASIS command

define [before] basis "[exp]" curve = min : max
   ebasis $curve = $min : $max
enddef
