Hello AeroDesign, Thank you for your question regarding waveform charts. You mentioned that you were acquiring data to be plotted in a chart from time 0 to 3 min. One possible solution may be to set the chart to update in relative time. To do this right-click the chart, go to properties, click on the Format and Precision tab. With the x-axis selected choose Relative Time. Also make sure that AutoScale x is disabled by right clicking the x-axis on the chart and unchecking this feature. In some circumstances a waveform graph placed in a loop might be more appropriate. It=92s hard to tell without knowing exactly what your application is or without seeing some simple code. An example of using a waveform graph called Cont Acq&Graph Voltage-Ext Clk.vi can be found in the shipping examples of LabVIEW 7. The following links also provide some information on this issue.
