Finding the maximum, minimum and other parameters from XY Graph

Solved!
Go to solution

Hi. 

 

I've created a VI to read data from OSIRIS file which contain 250 cycles of data.

The data is then shown on the XY Graph.  

I need to read the max, min and other parameters. I'm trying to use Tone Measurements, however it is not working as there is an error. 

 

"These cannot be wired together because their data types (numeric, string, array, cluster, etc.) do not match. Show the Context Help window to see what data type is required.

The type of the source is cluster of 2 elements.

The type of the sink is 1-D array of

double [64-bit real (~15 digit precision)] [numFlags=0x0].|" 

 

Thank you very much for reading and hope anyone could answer my doubt.

 

Regards,

Firdaus

Hi Firdaus!

 

I think the problem might be that you are using a bundle function to merge the signals, that creates a cluster which you cant input in the Express VI for tones. There are some options you can use, the first one is to use a Merge Signals VI (im attaching a pic) then get the parameters and input them into the graph. The other option could be to use the low lvl functions that are on the array Palette, called Array Max and Min.

 

Hope this information helps you, let me know if there is anything else i can do for you.

 

Have a great day!!
