I'm sure that I've done all things right but in the end the result I got is a sccatter plot that only shows the second datasets data.

  fig = plt.figure()
  ax1 = fig.add_subplot(111)
  ax1.scatter(train["ENGINESIZE"], train["CO2EMISSIONS"], color = "green")
  ax1.scatter(test["ENGINESIZE"], test["CO2EMISSIONS"], color = "red")
  plt.xlabel("Engine Size")
  plt.ylabel("Emission")
  
  plt.show()

Here You can see what's going on in my output in link below. It shows only red data(test data) in the output.

Where is the "output link below", please? For now I can only imagine what you are describing.

Also it helps if both plots have the same axis. That is, both have the same x-axis and then they can vary on their y-axis.

If so:

fig, ax = plt.subplots()

df.plot(kind = 'scatter', x= train["ENGINESIZE"], y = train["CO2EMISSIONS"], color = {'g'}, ax = ax)
df.plot(kind = 'scatter', x= test["ENGINESIZE"], y = test["CO2EMISSIONS"], color = {'r'}, ax = ax)
plt.xlabel()
