Rotation 12 last months

[cristianj23a]

Hi.

I have a line graph that shows me the accumulated rotations but I need to show the rotation of the last 12 months.

For example.

If in 2016 you have 4 months of rotation, then you have to show the four months of rotation and the 8 months of rotation of the previous year.

When you do not filter, the rotation of the last 12 months should automatically appear.

Attached my qvw.

Greetings.
