aztlan,
I'm assuming 2 things: you are using LabVIEW 7.1, and your data is an array of some unsigned integer type.
Displaying binary data formats in the LabVIEW digital graph is a commonly asked question. In LV 7.1, the digital waveform graph only supports the Digital Waveform Datatype. Therefore you must convert your array of unsigned integers into a Digital Waveform Datatype. The easiest method (not the fastest though) is to convert your integer array into a 2d array of booleans, then use a LabVIEW VI called DWDT Boolean Array to Digital.vi. I've included a VI that demonstrates how to do this.
Another thing to know is that in LabVIEW 8.0, a new VI was added that specifially converts arrays of unsingned integer types directly to DWDT.
