Greetings,
I can post as much code as needed but to be brief:
self.Plotty = QtWidgets.QWidget()
self.ui2 = Ui_Plotty()
self.ui2.setupUi(self.Plotty) -->[ In setupUi, there is:
self.graphicsView
= PlotWidget(Plotty) ]
self.Plotty.show()
self.trace1 = self.ui2.graphicsView.plot()
self.trace2 = self.ui2.graphicsView.plot()
Then somewhere else in the code I try:
self.trace1.setData(plotData_np_array[1::2], plotData_np_array[0::2], pen=
None, symbol='o')
and I get:
[14:11:27] Ignored exception:

When I don't add the other parameters:
self.trace1.setData(plotData_np_array[1::2], plotData_np_array[0::2])
It plots/displays with no errors, but I get lines connecting the points,
which I'm trying to avoid.
Use case: The User can plot "curve" data or "scatter" data on the same plot
window, depending on what different user selections. At least that's the
idea.
Thank you,
-Hey José
P.S. I didn't see a place to add tags to this forum post, did I miss that
somewhere? Tags: pyqtgraph, scatter, scatterplot, scatterplotitem,
