Plotting two lists with different lengths with interpolation

I need to plot two lists of numbers against each other, but I need to extend the range of both.

The first list contains the number of time a thing happens (which I'm simulating). The second contains the cumulative frequency. An example of both is:

number_of_times = [77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 90]
cumsum = [0.01, 0.02, 0.03, 0.04, 0.09, 0.16, 0.3, 0.46, 0.74, 0.89, 0.95, 0.99, 1.0]

How can I plot these against each other, with the x-axis (numvber_of_times) having a range of 0-100, but making sure that the cumulative frequency still matches up?

Currently I'm using 

plt.plot(num.keys(), cumsum)
plt.show()

but this just doesn't look that good.

You are currently trying to plot the keys of a dictionary num against the list cumsum. Simply feed the plot method the two lists as arguments, and set the x-limits with xlim.

number_of_times = [77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 90]
cumsum = [0.01, 0.02, 0.03, 0.04, 0.09, 0.16, 0.3, 0.46, 0.74, 0.89, 0.95, 0.99, 1.0]

plt.plot(number_of_times, cumsum)
plt.xlim(0, 100)

plt.show()
