Hi Stefan,
Have you tried giving the x,y data to the plot curve when it is created
instead of creating it then using setData? Like so:
curves = [0]*len(y)
for i in range(0,len(y)):
if headers[i][0:3] == 'fit':
print('try')
curves[i] = self.p.plot(x, y[i], pen='r',name='happy') #
crashes
else:
curves[i] = self.p.plot(x, y[i],
pen=None,symbol='o',name=headers[i],
symbolSize=1, symbolPen=self.colors[i]) # works
print('hi')
#curves[i].setData(x, y[i])
