In same window (pg.plot() is pyqtgraph.graphicsWindows.PlotWindow) you
initialize and plot new and new pyqtgraph.graphicsItems.PlotDataItem with
pw.plot(). It is better to initialize PlotDataItem first (pl = pw.plot()),
then just set the data it with setData(). Also your way of using of teml
variable is suspicious, but there isn't memory leak currently.
Cheers,
