Unfortunately, there is currently not an equivalent of LabVIEW's digital waveform graph in Measuremeht Studio for Visual C++. You can fake some of the features with CNiGraph. If you have Measurement Studio for Visual Basic 6.0 installed, you can see some examples of this in the VB DAQ\Digital\Digital Waveform and Digital Waveform Continuous examples. Also, attached is a sample Visual C++ 6.0 project that demonstrates how you can simulate some digital graph features with CNiGraph. There's also a screenshot attached that shows what this looks like. Hope this helps.
