The collect vi looks good, but seems only can process one dimension data, for 2 dimension data, need to use split and build up array again.
No, it can also deal with 2D arrays.
I'll have a look at your VI using the data constant, probably over the weekend.
Is that lower graph your xy history plot with 60000 points? You should definitely use a simple plot style (e.g. lines or single pixel points instead of fancy points).
Here is how to replace larger chunks. On the left I created 2 arrays. 100 rows by 2 columns of the number 2 and 10 rows by 2 columns of the number 1. I placed the smaller one into the larger starting at row 3 using the replace array subset function.
