Not something I had originally intended and it's far from complete, but an easy feature to add using gnuplot.
Install gnuplot and checkout the code from svn to use this feature.
Eventually will change to a process that prompts for labels and other options and saves the steps as a lua/gnuplot script for easy recreation.
Version 0.7 of luacalc has been released.
This version contains several bug fixes and improvements to the function system including a documenting/listing feature.
This is the first beta release of luacalc since joining sourceforge. You can find the download at:
* Copy/Paste from other spreadsheet programs
* A few simple functions, which you can easily modify/add
There is still a bit of work needed before a 1.0 release such as a built in help mechansism for functions.
