spilt 2D array and use the deatels

[yechielo]

Hi, i wrote a simple program to read info from DAQ, the output is 2D array, I need to sub a constant from X, how can i do it?

see atatch for the program,

Thx a lot for the help,

Hi yechielo,

if you connect row and column on the "index array" function, then you will get a single element.

Hi Mike,

i dont need to use a singlr one element, my Y array is around 0.59, I need him around 0, that mean i need to sub 0.59 from Y array

Thx

By sub, you mean subtract?

If so, you can just use the - function from the numeric palette with 0.59 as 1 number and labview will automatically subtract it from all elements.

Steven, you right, i want to do that, but i dont know how to spilt the 2D array to x array and y array

see atach where i want to sub

Thx

The Y values are the values in the array, and the X values are the element numbers of the array. So you don not need to seperate or split your array.

yechlielo,

Your program does not make any sense. You have a shift register that does nothing and you convert everything to DBL. When you save the data, you are throwing away all data except for the very last iteration and you are throwing away all timing information.

To plot 3 different graphs, you could just keep it as dynamic data and then use the Split Signal function.

Denis,

Thx for your help, i just test the save to file in my program and i saw that my data didnt saved, can you advise me how to save all the measured data to file?

thx

Hi yechielo,

you save only the data of the last iteration. To get all data use the build array function and connect the left side of your shift register and the new data to it.
