LabVIEW
Is it true that the limit of the graph shown in the report VI is only limited to 0.1?
Hi Sammy,
It's still not clear what you are asking about. If you are referring to the "Report" Express VI, it will by default print or save a report with images of a Waveform Graph that is autoscaled to fit the data you provide to the "Signal 1" and "Signal 2" terminals. If you connect a default "Simulate Signal" Express VI, the graph in the report will show the full -1.0 to 1.0 range, since the signal never exceeds this range. Here is my example:
If your report only shows -0.1 to 0.1 it's most likely because your signal does not exceed this range. It is NOT possible to disable the "autoscale" feature from the "Report" Express VI. If you want this type of customization, you need to use the lower level Report Generation VIs in the Report Generation palette.

hi ,
the graph in the diagram is a supposedly sine graph but with amplitudes ranging from -0.001 to 0.001. is it possible for me to shorten the range so that the shape of the graph can be accurately shown???
Hi Dennis,I have successfully generated the report with the graph being abled to display the y-axis. But now, the table below the waveform cannot reflect the actual values of the x-axis. The table keep displaying 3.21799E+9 for all the x- axis values. The table below is a portion of the report. Sammmy

Hi Sammmy,
That's because you are passing the time as a value to the report. Time is in LabVIEW defined as the number of seconds since midnight January first 1904. If you change the formatting of the cells in the spreadsheet to add more significant digits, you will see that the numbers are not the same. Please submit your VI or otherwise let us know how you are passing the time information to the report. It should be a simple task to change it to something more familiar.
By the way, do you want the report to show the absolute time and date or do you only want the relative time to the beginning of the data collection?
