Hi AH,
If the x-axis scrollbar is not being used, the current x position of the waveform chart is simply the maximum value on the x-scale. First, make sure to turn on Autoscaling on the X-axis via the Waveform Chart property XScale.ScaleFit with a ‘2’ constant wired as input. Then, to read the current x position, use the Waveform Chart property XScale.Maximum.
Another option is to use the initial x-axis value (XScale.Offset) and add the length of the chart history data to that value. However, note that this only works is the chart history buffer is not full. Or, just have another variable that tracks the number of data points that have been outputted to the chart and add that value to the XScale.Offset.
Hope this helps. Good luck!
