LabVIEW trivialness -3

1. A strip chart shows running data continuously scrolling from left to right across the chart. A scope chart shows one item of data, such as a pulse or wave, scrolling partway across the chart from left to the right. A sweep chart is similar to an EKG display. A sweep chart works similarly to a scope except it shows the older data on the right and the newer data on the left separated by a vertical line.

2. Array index is in the range 0 to n-1, where n is the number of elements in the array.
3. virtual channels: A collection of property settings that include a physical channel, the type of measurement or generation specified in the channel name, and scaling information
4. Waveform chart: get one data and show one data, can be used inside loop.
Waveform graph: get all data to an array, jump out of the loop to graph
