The messages you saw are not errors, but merely debug messages. They show that you are missing packages for two of the three available ploting backends: - MatPlotLib - PyQtGraph If they are available pre-packaged for your distribution you can simply install them. If not, at least for PyQtGraph it should be enough the download the source code and put it into your Python path.
Since these two are missing, the least comfortable backend has to be used: QwtDataPlot. This one does not feature auto-scaling and other nice features, which the other two backends have. So if you want this, I suggest installing PyQtGraph.
