My name is vijay. For the scaling on the x axis,can u please tell me what X0 and delta X denotes. What scaling factor are they reffering too? thank in advance. Also in order for you to see the binary representation of your digital inputs u can open up the "read from one digital port" VI located under data acq, digital i/o, immediate digital i/o. Then u can wire a graph at the output from the pattern node before number is converted to boolean. Hope that helps jonathan!
