Recording data from graphs

[AlainKabs]

Hello everyone.

I have a dynamic array which results from calculations then plots graphs. I would like to record the data to view the graphs elsewhere or later.

My routine does not work, can somebody explain me why?

NB: this is based on an example I found in the help window of "Read from binary file"

Hi Alain,

in your picture there is no "Dynamic Datatype" array. There is no "dynamic" data at all. All I see is a 2D array constant…

My routine does not work, can somebody explain me why?

What does not work?

Which errors do you get?

What have you tried to debug your routine?

 Hello Gerd.

in your picture there is no "Dynamic Datatype" array. There is no "dynamic" data at all. All I see is a 2D array constant…

When I said I had a dynamic array, I did not mean Dynamic Datatype array but an array (in orange, on the left) that may vary in size, depending on previous calculations.

What does not work?

What should happen is the indicator Result reading should be active and look like Reading,

Which errors do you get?

What have you tried to debug your routine?

I do not get what you mean here. I think I have not tried to debug anything yet.

Here is a repost with simpler base path and file name...

(to try the routine, just drag and drop this image in the Block Diagram of a blank VI)

i really also want to try this program, it is related to my labview program to analyze raw  data from satellite and analyze all the data  back to its original messagecamera raw data, aodcs , high voltage solar array data etc

Thanks...am new to labview can you illustrate some of the blocks for me to easily pick  search on my labview program version 2012?

Hello GerdW,

Thank you very much, this works just fine!!!

Can you explain me why you use this? 

Thank you again.

Best regards,

Alain.

Hi Alain,

IndexArray: ReadFromBinaryFile expects a description (or the datatype) of ONE data element in your file. As you wrote an array of elements you need to provide the scalar element as datatype description.

-1 constant: read the help of ReadFromBinaryFile. It explains the "-1"…

Hello mon39Por,

Here is a repost of my VI with all labels on it.

As I said earlier, the second part of my VI is based on Right-click < File I/O < Read from binary file < Detailed Help < 3rd example. Then I merged both VI's.

Regards, 

Alain.

PS: Are you from France?

Ok, now I get it.

Thank you again.

Alain.
