Shift Registers b. jitter can be used to provide displacements along the horizontal axis, which is useful when there are large clusters of data points. This function works in two modes: either appending elements to an n-dimensional array, which is the default mode, or concatenating multiple arrays. Because of this I am having trouble with the labview graphs and charts as the function produces its own time values. Three common types of graphs/charts are waveform charts, waveform graphs, and XY graphs: - Waveform charts: Display single or multiple traces. ”. 8^{ In Labview 2009 I was able to reproduce the issue, while in Labview 2010 version all update modes were displaying data correctly. .

When a predetermine amplitude is reached, I would like to continue displaying signal for period of time before halting. LabVIEW provides both a Chart (for evolving data, plotting the "latest point" each time) and a Graph (for static data, where all of the data present is plotted at once). It can show as many waveforms as there are channels in the scope card, plus references, if you read them in. 1. Strip Chart. A "Waveform Chart" doesn't necessarily have anything to do with Waveforms -- it is just a way of plotting things (like Waveforms) that consist of equally-spaced (timed) variables, so the X axis is effectively equally-spaced Sampling Time, and hence not explicitly specified. Re: Chart time base formatting.
