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 starting | Test Score |
|---|
PersonA | 1 | 26 |
| PersonA | 2 | 34 |
| PersonA | 5 | 32 |
| PersonB | 1 | 31 |
| PersonB | 3 | 19 |
| PersonB | 9 | 41 |
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?
