K Waris Posted October 12, 2013 Report Share Posted October 12, 2013 My vi has a requirement to display the last 500s worth of data and then wipe off the waveform chart offand plot again. I achieved this but having only one problem. My chart mode is scope mode My chart history length is set to 500000 Acquisition frequency is 1000 Hz X scale offset to .001s I get nice waveform plotting from left to right, after 500s the data is wiped off and labview replots it from left to right however for the very first time the vi is run, labview plots the waveform chart from right to left. Is there anyway I can always plot it from left to right Best Regards K Waris As a matter of fact, I have achieved this- Just used the property node history and initialized the history array to index 500000 and it worked a treat- Quote Link to comment
