I am a beginner to Labview. I made a very simple data acquisition file using the DAQ Assistant. What I want is to write data to file and display the realtime data on the waveform chart with respect to the "elapsed time", say, from 0 second to 500 seconds. However, no matter how I change the X-axis properties of the chart, it always shows the real time in terms of hh/mm/ss/dd/mm/year in absolute time setting or shows a very large number if I select the relative number. Could somebody tell me where is the problem? I attached the file with this message. Thanks.
