how can I put data in an array which will be used in SPC plotting

[chrisboo]

In my program, it will generate data continuously and I would like to store these data time to time in an array. Could you suggest me a method?
For example, 1.77,1.67,1.56,1.89,1.99... (these data generated continuously)
1st second: 1.77 1.67,1.56,1.89,1.99( store in array)
After 1 second: 1.67,1.56,1.89,1.99,1.33 (remove the first one data in the array and replace it with the following generated data)
How can I remove the data in the array and replace it with the other data?
Could you give me some examples?
Thanks

Check the attached VI. It includes two methods. You can choose the one you like. I prefer the bottom one because only one extra memory for the subarray is created. The top one makes two copies because of the resize.
