XY Graph - limit size of X shift register to N elements

Solved!
Go to solution

Hello,

 

I am feeding two shift registers output to a XY Graph.

 

On the Y axis I am plotting the value of data aquired with NI CAN Interface.

 

On the X axis I am showing the data timestamp. What I need to do is to window the X axis, so that Graph only shows data aquired in the past N seconds (N selected by user)

 

Therefore I need to limit the size of the array to N elements. I tryed "Reshape array" on the x shift refister but it does not work.

 

Any ideas?

Hi loba,

 

idea: use ArraySubset instead of ReshapeArray, when you want to work with array subsets…

Best regards,

How large is the array? Another issue you may need to consider is performance problems resulting from unnecessary copying of large datasets. Can you say a bit more about what you are doing?

I was trying to set programmatically the max and min value of the x axis but I didnt take of the AutoScale so it was going bunkers
