I'd like to display a scatter plot with axes passing through the origin, which is in the center of the plot. This is how I setup the plot:

plotWidget = pg.plot(title="Sensor position")

scatter_plot = pg.ScatterPlotItem()

scatter_plot.setData(pos=pos)

plotWidget.addItem(scatter_plot)

plotWidget.setRange(xRange=(-2.0,2.0), yRange=(-2.0,2.0))

It looks like that an AxisItem can only be positioned at ‘left’, ‘right’, ‘top’, or ‘bottom’ positions. Are there alternatives?
