    Why do data points disappear when I choose a continuous scale?

      Hi,

       

      I have a line graph that graphs test results per person (for over 30 people) after certain numbers of months since starting a program. An example of how the data is structured is below:

      Person
      Months since startingTest Score

      PersonA

      126
      PersonA234
      PersonA532
      PersonB131
      PersonB319
      PersonB941

       

      Months is on the x-axis (goes up to around 60), Test Score is on the y-axis, each person has their own line (for over 30 people).

       

      Not every month will have a test score, meaning that when the x-axis does NOT have a continuous scale, the distance between Month 24 and Month 36 can look the same as the distance between Month 1 and Month 2 (which is not ideal).

      But when I choose to have the scale be continuous, the data for several subjects disappears from the graph. Why does this happen?
