Hi,
I am new to using PyQTGraph but I encountered a very weird issue.
Every time I add a ScatterPlotItem, while there is n existing LinePlotItem,
the LinePlotItem disappears.
Here is the sample code that I run.
I am sure I am missing something very simple, but any help would greatly be
appreciated.
Thanks in advance for the help.
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
import numpy as np
from pyqtgraph.Qt import QtCore, QtGui
import pyqtgraph as pg
import pyqtgraph.opengl as gl
import pyqtgraph.examples as ex
import numpy as np
import sys
app = QtGui.QApplication([])
w = gl.GLViewWidget()
w.setWindowTitle('pyqtgraph example: GLSurfacePlot')
## Add a grid to the view
g = gl.GLGridItem()
w.addItem(g)
## Add Axis
a = gl.GLAxisItem()
w.addItem(a)
# add a line
el2 = gl.GLLinePlotItem(pos=np.array([[0, 0, 1], [1, 1, 1]]), color=[1, 0.0,
1., 1.], width=10)
w.addItem(el2)
# add scatter plots
el1 = gl.GLScatterPlotItem(pos=np.array([[0, 0, 1], [1, 1, 1]]), color=[1, 0.0,
1., 1.], size=10)
w.addItem(el1)
w.show()
