ok here comes some more code:
def plot_angles(results, axes):
lk.acquire()
x = list(results[0])
y = list(results[1])
lk.release()
p = axes.scatter(x,y, c = range(len(results[0])))
axes.set_xlabel('psi')
axes.set_ylabel('delta')
colorbar(p)
def update_figure(self):
plot_angles(results, self.axes)
self.draw()
_tkinter.TclError: bad screen distance "320.0"
