How to get a simple plot with pyqtgraph

Question

I have this code:

plot = pg.PlotItem()
plot.plot([1,2,3,4], [3,4,5,6], symbol='o')
viewer = pg.ImageView(view=plot)
self.tabLOs["Server"].addWidget(viewer)

to do a quick proof-of-concept for making a few simple graphs to display system data. I want a very simple graph that I can update as the data comes in. The code above gives me a graph but with an interactive area to the right. I've found other classes that give me just graphs, but they aren't able to be used with addWidget and/or have the plot() method. Is there a PlotItem equivalent that doesn't have all the extra stuff that I can just add to an existing layout with addWidget?

EDIT: pg is from "import pyqtgraph as pg" and tabLOs["Server"] is just a VBox layout.

I think you want to create a pg.PlotWidget which can be added to your QVBoxLayout. You can then get the plot item using my_plot_widget.getPlotItem() (this method negates the need to create your own PlotItem).

Perfect. Worked like a charm. For future readers, I switched to this: plot = pg.PlotWidget() pi = plot.getPlotItem() pi.plot([1,2,3,4], [3,4,5,6], symbol='o') self.tabLOs["Server"].addWidget(plot)
