I believe I posted this either here or in the issues section on github at
one time, but I never heard anything so I'm trying again
i have a PlotDataItem and I'm trying to connect the sigPointsClicked signal
to a function.
The problem is that when I click on a point, I get the following
TypeError...
| File
> "/home/jwebster/anaconda3/envs/py3/lib/python3.6/site-packages/pyqtgraph/graphicsItems/ScatterPlotItem.py",
>
> line 817, in pointsAt
> | s2x = s2y = ss * 0.5
> | TypeError: can't multiply sequence by non-int of type 'float'
>
I don't know that this will get fixed anytime soon, and I really need this
to work
Can someone suggest a workaround?
this is how I create the curve and connect it.
self.b_curve = pg.PlotDataItem(x=self.t,
y=self.b,
pen=None,
brush=bcolor,
symbol=symb,
symbolPen=bcolor,
symbolBrush=bcolor,
symbolSize='5')
self.b_curve.sigPointsClicked.connect(self.pointsClicked)
def pointsClicked(self, points):
for idx, point in enumerate(points):
print('{}: x={}, y={}'.format(idx, point.x(), point.y()))
