Splitting array data

[AndrewRae]

Hello

I’m new to LabVIEW and was hoping someone could help. I am sorry in advance if I ask basic questions but please keep in mind I am new however am willing to learn.

I am trying to send data from serial port and trying to plot the data, however the data comes as an array of three values at a time. I want to learn how to split the array of three to each individual values. The reason being, I would like to plot each value on a graph that plots the incoming values against time. The data would be fed continuously with different values each second.

Hope it made sense

Or is there a way to assign the variable from the serial to the graph for example if the data is:
A=23
B=24
C=25

Is there a way to plot a graph that will only plot the data that comes with the name A against time and as every second new data is received A will be automatically plotted within a graph with only A data.

I would like to have three graphs A, B and C.

 

Hope that made sense

Hi Andrew,

 

With reference to your first post, you can use the index array function to get the individual elements out of the array.

 

 

Are you able to control the format of the data from the serial port?

 

Could you provide the a sample of the exact data the is read from the serial port? That would help in working out how to split it into the three graphs.

I guess you are using a WfmChart and try to plot the array values in the chart as they arrive?

 

A 1D-array fed into a WfmChart will update one plot with three new values.

But, if you just add a build array on the 1D array, data will be plotted in three individual traces.

Hi Greg

 

Thank you for your help. The data will be recieved at random times and any order. There is a format to each data.
 

Mellroth, I was planning on using theWfmchart and thank you.
