Thank you for contacting National Instruments. To get started, I recommend taking a look at the NI Example Finder (Help>>Find Examples in LabVIEW). In the NI Example Finder, a list of folders will appear. Go to Hardware Input and Output>>DAQmx>>Analog Measurements (DAQmx will be in the list if you have installed the DAQmx drivers).
To construct images, take a look at the Picture Functions Palette. It is located under All Functions>>Graphics & Sound in the Functions Palette.
