I have a python code in which I calculate a quantity for a large number of values of a parameter and then plot the quantity as a function of a parameter. Here is an example
t = np.linspace(1,100,10000) q = np.zeros(10000) for i in np.arange(10000) q[i] = func(t[i]) plt.plot(t,q) plt.show()
However I want that the plot to get dynamically updated such that every time a new element of the q
array is calculated it is added to the plot. How can I do that?

from pylab import * import time ion() tstart = time.time() # for profiling x = arange(0,2*pi,0.01) # x-array line, = plot(x,sin(x)) for i in arange(1,200): line.set_ydata(sin(x+i/10.0)) # update the data draw() # redraw the canvas print 'FPS:' , 200/(time.time()-tstart)
