Back in the old ETH days, I got used to Matlab, which we used for a variety of tasks, among them data analysis, figure creation and even real-time control. For the task of figure plotting I have recently discovered matplotlib – an open source alternative, which can be used by python scripts. The plotting functions sound very familiar for Matlab users. So I am again amazed by the progress of open source software.
For my current project that deals with testing tools (doing functional and repetitive tests) I will probably make use of the matplotlib functionality to provide some output graphs after tests.
