LabVIEW what several options for displaying data. A waveform chart is great if you receive one point at a time and want to plot the data in series. A waveform graph is good for plotting arrays in a time series fashion. An xy plot is good for connecting points that do not occur in a series. This plot offers the most flexibility in graphing points with different x values.
It is often hard to keep what structure goes two what display option. As a cheat, I right click on the chart in the block diagram and slide the mouse to create >> (either a constant or control). This way you can get a model for the data you want to input.
You may also want to look at the shipping examples that come with LabVIEW. In LabVIEW 6.1, goto help >> find examples >> fundamen
tals >> graphs and charts.
