how to use Pyplot module of matplotlib to plot two arrays of data

Question

I wrote this code: I wrote this code: I am trying to plot the two arrays x "the data number" and y "the data itself"

for t in range(1, 281):
    data[t] = (3600 + (240 + t * 4) + 281)

for r in range(1, 281):
    sn[r] = r
x = np.array(sn[r])
y = np.array(data[t])
plt.plot(x, y)

where is the problem

Add plt.show() to actually show the plots.

After plotting the data with plt.plot(x,y) you need to show the plot with plt.show(). Alternatively you can save the plot directly to disk with plt.savefig("Myfile.png",format="png").
