Plotting a dictionary with multiple values per key

Question

I have a dictionary that looks like this:

1: [\'4026\', \'4024\', \'1940\', \'2912\', \'2916], 2: [\'3139\', \'2464\'], 3:[\'212\']...

For

Answer 1

You need to construct your list of Xs and Ys manually:

In [258]: b={1: ['4026', '4024', '1940', '2912', '2916'], 2: ['3139', '2464'], 3:['212']}

In [259]: xs, ys=zip(*((int(x), k) for k in b for x in b[k]))

In [260]: xs, ys
Out[260]: ((4026, 4024, 1940, 2912, 2916, 3139, 2464, 212), (1, 1, 1, 1, 1, 2, 2, 3))

In [261]: plt.plot(xs, ys, 'ro')
     ...: plt.show()

resulting:
