someday maybe I can be talked into writing a full article instead of just releasing little bits. I have been looking at different graphing utilities including matplotlib and the newly released pyqtshell (using matplotlib)for the purpose of graphing out columns of csound spreadsheet data. For the most part it these are not that usefull unless you want to generate a wave of some kind and then draw the picture. I did come up with a freeware package that can be coxed into graphing the data from a csound score (with a little help from python you can create spreadsheets of the columns you want to graph ) called es-plot. It is nothing fancy but it is freeware and it can be included with exsisting packages (I am overdue for a new release of dex tracker).

I have released the python script here

If there is anything that can be plotted, or other ways to do it let me know and I will include them.
