I need to do a presentation of a product with charts (Pie and Bar charts).
I use LibreOffice for documentation, but charts are not very beautiful.
Someone could recommend any software to generate charts ?
It's very important that charts will be beautiful, with 3D effect, gradients, etc.
Thanks
R has very good charting capabilities (click here for a gallery of examples with sources).
It is free and installable from the repositories. The main package is
r-base
, several additional packages are also available.Note that R is not a spreadsheet. It is a programming environment -- a bit of work is necessary to obtain what you want. There are, however, several tutorials (this and this for pies).
I recently discovered gnuplot is not as difficult as I thought. New version can output in HTML5. As per piecharts try circles. http://gnuplot.sourceforge.net/demo_4.4/circles.html
Not sure about the 3D effects but you can output it as an SVG and have a play around with an vector graphics editor like inkscape.
Make sure you tried mathgl too. It's specifically made for nice 3D charts.
