GTK+ Forums

I have developed a plotting library (currently only has linear x-y and polar types) as I am a scientist and unhappy with the way a lot of data visualisation programs do graphing (e.g. Matlab/Scilab/Origin; all produce laughably unprofessional plots). Cairo graphics being vector based offered a good solution to the resolution issues in taking screenshots of these plots. I also wanted it to be fast as I often deal with sets of 64k data points and had seen major performance lags in other plotting modules (e.g. in OpenOfficeCalc).

The source code can be obtained from https://github.com/pchilds/GtkPlot/downloads

I have a version for gtk2 and for gtk3 in order to set which one gets built run from the command line where x is either 2 or 3.
For those on a debian based system there is also a debian branch containing the packaging scripts. After reversioning just run from the command line in order to build the .deb binaries.
Otherwise use the standard autotools based installation (instructions in the INSTALL file)

Screenshots are below from test programs (included in the code as TestPlotLinear and TestPlotPolar). I welcome all comments about my ignorance and how to improve the program/packaging. Please let me know if you have any features you'd like from it. the more people that use it and the more feedback I get, the better it can become.

Features:
* Multiple Plots (data from a 2d array is selected by index, length and stride to allow flexible formats)
* Automatic axis rescaling to nice neat integer * power of 10 values through the _update_cale_pretty functions.
* Cut axes (i.e. a wiggle is inserted if the range doesn't include the origin) to both maximise the view and avoid confusion (e.g. if axes don't cross at the origin).
* utf support through pangocairo
* display configurability (points&|lines, linewidth, pointsize, colour)
* Can print the graph to png, svg and eps (useful for those who use latex).
* zoomable ranges (in single click or drag; horizontally, vertically or both -- radially /azimuthally for the polar case)
* signal emission for cursor coordinates
* accessibility support (in progress)
* and lastly - bloody fast! (due to the painful way in which I code)

Paul,
while trying to install this project, I am facing problem:




I am using fedora 17


But as I cant (probably because I shouldn't...not sure though) attach config.log, can you make any guess where I am goung wrong?

I must have forgotten to include math.h from the configure.ac script. Ran automatically on my system so I never noticed. Sloppy mistake. I'll try to fix it with my next commit.

ok should work but haven't tested on an rpm distro yet.
Latest news is I have also got binaries for running it on a raspberry pi as well and it works quite nicely even given the slower processing speed.
I'm keeping the binaries in http://members.iinet.net.au/~childs/packages/ at the moment.
Rudra, if you still can't get it to install let me know. I think there are utilities that can convert between rpms and debs that work in most simple cases so you might be able to use a .deb.

Paul,
I failed to convert the debs to rpm. Will you mind send me a tar-ball of the source code? (github is not showing any option of downloading the full package)
