Hi Hamza, It's missing from the documentation of PlotDataItem (http://www.pyqtgraph.org/documentation/_modules/pyqtgraph/graphicsItems/PlotDataItem.html) but there is a clear() method, which should do what you want. Alternatively, you could probably setData(0).
(I find looking at the source code found behind the green "[source]" link in the documentation can reveal a few useful undocumented features).
