Hi, 1. The graph interprets the data as points ont the graph and increments the x index by one starting at x=0. If you want a different starting point or increment, then use the bundle function. Check the graph examples in the "LV examples". 2. In this case you've to use a continous data acquisition (HW timed). If you're using a NI board, then check the countinous I/O examples in the "LV examples". 3. Use a XY-Graph which you'll find in the same palette as the chart and graph. The XY-Graph accepts a cluster which contains an x array and a y array.
Hope this helps. Luca
