Some visual progress....

Okay so now I have the octave console done, and now I am working on getting a nice GUI around the plotting stuff.... Well it seems the authors of GNUPlot are better at making graphs than writing code...

Needless to say I now have a Qt widget that wraps GNUPlot.

Currently I have only the basics covered. Plot works for most simple cases, and you can set the scales and axis titles. No 3D options yet, or export features... but at least now I can give a nice integrated plotting utility in my Octave wrapper. The goal is to allow a more pleasant interface to manipulate the plot once its been generated by the script...

In completely unrelated news, the basement has been mostly cleaned in preparation of the KDE Halloween party on Friday the 29th, followed by a hackfest Saturday.

Yeah, nice one! That seems easy enough to use, although maybe not so much when you just have raw data.

Maybe now we need Gnuplot to export graphs with transparent backgrounds... :)

PS Anyone know why kdedevelopers.org does not remember my login?

... i am using this to plot raw data from gnuplot. the function input is just an example.

also, gnuplot can do transparency in graphs since 1998(?). Its an option on the png/gif export.

although I'm probably going to use kimageio to handle the pixmap based plots, and gnuplot to handle vector formats. This should give a very flexible set of export options.

is the source on-line somewhere? gnuplot is great, and a karm user actuall submitted an awk script to plot historical time card data.

sorry i'll miss you guys on halloween.

... i hope to have an early release of my Octave IDE stuff this winter here. Currently I can only plot functions, and data files with only limited options. I need to cleanup and streamline the code, then it will be genericly usable. if you want to help drop me a line, and ill get some cvs setup.
