Use the Analytics Viewer to examine data points, present those points in informative ways, and zoom to critical periods within the span of recorded data.

1. Click the Maximize icon to dedicate the workspace to the Analytical Viewer by removing other interface elements from the screen. To return to the default view, strike the Escape key or click the eXit icon.
   
2. Click the Show/Hide Options icon.
   
   • On the Options panel, control what data appears on the chart. To manage screen space consumed by the Options panel, click the arrows beside the section headers to hide those options.
     • Graph Type: The chart defaults to Raw or Average. Be aware that when you choose Count, the chart will no longer display any units, as the units are now effectively a count of the data values.
       
       • Resolution: Choosing a smaller resolution option, like hour or day, means the system must process more data and may take longer to assemble the chart.
         
       • Y Scaling: A linear scale is a line marked at intervals according to the distance represented. A logarithmic scale is a nonlinear scale used when there is a large range of quantities. It is based on orders of magnitude rather than a standard linear scale, so each mark on the scale is the previous mark multiplied by a value.
         
       • Regression Type: For the Regression to be visible in your chart, choose Linear for a straight line or Polynomial to see curves.
         
       • Settings:
         
         • Enable Comparison – Check this box to view the differences in the data from two periods.
           • Check the box to activate the Comparison Start field then choose a date. Two traces and two X-axes appear in the chart. A second name is added to the Legend; the © at the end of the addition indicates that this is the comparison line.
         • Split Axes – Multiple points with common units will share a plot line on the Y-axis. Check the Split Axes box to give each point their own Y-axis and label, allowing them to be scaled independently.
         • Show Logbooks – Check this box to mark Logbook entries with a book symbol. Click the book symbol in the chart to open the entry.
         • Show Legend – Check this box to present point names in a legend at the foot of the display. Click these point names to hide/display individual traces.
           
         • Display Full Path – Check the box to add a point's Tree Navigator location to its name in the Legend.
           
         • Show Data Values – Check the box to display the numerical quantity of a presented value atop the representation in the chart. Regression elements are also accompanied by numerical quantities.
           
3. Click the Chart Details icon.
   
   • The Ident column shows the color for each point's trace on the chart.
   • Check the Show Plot Box for each point's trace that you wish to appear in the chart. Conversely, removing the check from the box hides the point's trace.
   • If your Points are configured with alarms that are enabled, check the boxes for those you wish to appear in the chart.
   • Your choice from the Chart Type drop-down determines the appearance of a point's trace.
     
   • Use the Scaling tab to specify a manual scale per Y-axis.
     • Enter a numeric value in each relevant field then click Apply.
     • To revert the changes, check the Autoscale box for each relevant row then click Apply.
       
   • The View as Table tab displays all values on the chart in a table. Each Point/Indicator is displayed along the top with 2 columns: a Timetag and a Value. Clicking in any Timetag or Value column header sorts the column.
     
   • Open the Point Summary tab to see a Count of how many values appear in the chart. Columns display Min, Max, and Avg values for the selected period per Point/Indicator. When you drag the grips of the Navigator Trace, these values update accordingly.
   • Click a column heading to sort the values beneath it.
     
4. Click in the Graph Start Date field then enter a date in YYYY-MM-DD format or choose a date from the calendar. Repeat this process in the Graph End Date field then click the Refresh Graph icon.
   
   Note: If you are dealing with high volume data and require hour and minute values in the Start/End Date field, then click on the hour indicator at the bottom of the calendar pop-up. Options 00 to 23 become available, so select the desired hour. Click on the minute indicator then choose from options 00 to 55.
   
   • The chart displays data for the defined period.
     
   • The Navigator Trace that runs just below the chart contains a representation of the data set and gives an indication of the current zoom level. Slide the grips at either end to expand or restrict the period of data presented in the chart.
5. Drag the left grip of the Navigator Trace in either direction then click the Synchronise Start/End Dates with Current Zoom icon. The chart zooms in or out to establish the position of the grip as the new Start Date for the period of presented data.
   
6. Click the Reset Start/End Dates to Defaults icon to return the full span of data.
   
7. Move your cursor into the chart and hover over a data point to see the information represented by the line or column or spline.
   
8. Click the Export to Excel icon if you wish to create a spreadsheet of the data from the chart.
