Plotting logged data

This section describes how to use and customize the Log View Plotter to view logged data in a graphical representation. Use the Log View Plotter to graphically show trends in numeric data, display logged waveforms, display phasor diagrams, and perform harmonics analysis on waveform data. You can also plot Sag/Swell voltage disturbances and compare them to industry standard voltage tolerance curves (such as the CBEMA/ITIC curve).

TIP: You can copy information displayed by Vista Log Viewers to the Windows Clipboard and paste it into other Windows applications.

Plotting logged data

NOTE: To plot high speed transient waveforms, use the Web Applications waveform viewer in Diagrams or Alarms. High speed transient waveforms cannot be displayed correctly in Vista.

1. Select data from a data log viewer:
   • To graph trends for all parameters over a particular time span, select a group of rows.
   • To graph a trend for a specific parameter using all available records, select an entire column.
   • To graph multiple parameters over a specific time span, select the first cell in the desired range and drag to highlight to the last cell of the range.

2. Select Edit > Plot Selected Data or click .

   Vistaplots the data and displays it in the Log View Plotter window.
