Maybe. If you know how long the test is going to run and how many acquisitions you'll be taking then initialize the chart history at the beginning and use property nodes to set the x range minimum to zero and set the x range maximum to the total number of readings you'll be taking. You'll also have to set the chart history length to be the same or larger than the total number of acquisitions. If the test is intended to run until someone clicks a stop button and you might have a wide variation in test times (from minutes to days), then you might have some problems
