-- d0 is what you judge as "is at about zero" for your input -- select it such in size, that you don't get an "overflow" or -- such that 1/d0 is your max ± vertical plot value (= clipping)
function f3 x local d0=0.001 if abs(x-3) < d0 then return empty -- don't plot in case of an empty return else return 1/(x-3) end f3 _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
