Please post your code (preferably in 2020 or earlier), or we won't know what the problem is in your configuration.
I believe you are using the same Samples to Read and the Rate (Hz) (see DAQ Assistant-Setting the Sample Rate and Samples to Read), and writing to a waveform graph. The DAQ Assistant returns the data and overwrites the waveform graph every second.
