here is my issue. I have a chart where I add data on a weekly basis. I would like to present only last 4 weeks in a chart.
this is my data:
| module | week1 | week2 | week3 | week4 | week5 | week6 | week7 | week8 | week9 | week10 |
| module A | 5 | 5 | 6 | 6 | 7 | 8 | 12 | 15 | 15 | 16 |
| module B | 1 | 1 | 1 | 1 | 1 | 2 | 2 | 2 | 2 | 3 |
| module C | 5 | 5 | 6 | 6 | 6 | 6 | 6 | 6 | 6 | 8 |
| module D | 2 | 4 | 5 | 6 | 6 | 8 | 10 | 11 | 11 | 13 |
i would like to present data only from week 7-10, but next week to present data from week 8-11 and so on.
thanks,
Yuval
