Try my Veusz plotting app and library - <a href="http:&#x2F;&#x2F;home.gna.org&#x2F;veusz" rel="nofollow">http:&#x2F;&#x2F;home.gna.org&#x2F;veusz</a> - it has a nice interactive GUI, is python scriptable and extensible via plugins. It&#x27;s based around Python, Qt and numpy. It can export to PDF, EPS, SVG and bitmap formats.
