Probe Shows Data, Chart Does Not

[Ano_Ano]

Hello,

I have a while loop

I am using a USB-6255 to output/input data and it works fine (see part A & B in picture)

When I added code (see part C) to input temperature data from a NI-6213 a strange thing happened.

The graphs stopped showing data where as all indicators and probes show the data just fine!
The code for the temperature works fine alone

Why is this happening and why only graphs/charts are influenced?

Is there a problem using many acquisition devices in the same loop?

Here is another picture.
The text output is directly connected to the waveform graph
I get data via text but there is nothing displayed on the graph

Why is this happening?
All the graphs in the vi do not work

Hello Ano Ano,

Thank you for your post on this forum.

Can you attach your VI please so that I can have a look at your code?

Thanks,
