Starting in NiagaraAX-3.4, this “play” button icon is available for the History Table view. Click the button to start On Demand History updating. The button changes to a “pause” button icon while On Demand History is active. See also, About On Demand history views.
Data parameters

These controls include Delta (for history logging) and Time Range settings.
- Delta reporting option
  
  This option is useful for history logging, when you want to display value changes (delta) in your report. Refer to About delta logging for information about delta logging.
- Time range option list
  
  This list has a variety of predefined time range options, including an option that allows you to restrict your data presentation to a particular date and time range that you specify.
Title bar

This area of the table displays the name of the data collection on the left side of the title bar and in some tables (collection table, history table, alarm extension manager, and others) displays the total number of records in the table on the right side of the title bar.
Column headings

Each column of data has a title that indicates the data type.
Column boundaries

Each column has a movable column boundary that can be used to re-size the column using the mouse control. Stretch or shrink column width by dragging the column boundary, as desired. Use the Reset Column Widths menu item to reset all column widths to their default size.
Table Options menu

This menu is located in the top right corner of the table and provides one or more of the following controls and options. The standard table options menu includes the following items:
- Reset column widths
  
  This menu item sets all columns in the table to their default widths. This is useful if you manually changed widths of columns, and now some contents are hidden (even after scrolling).
- Export
  
  This menu item opens the Export dialog box where you can choose to export the table to PDF, text, HTML, or CSV (comma separated variable).
- Context-sensitive menu items
  
  Additional context-sensitive menu items appear in the table options menu, depending on the component that you are viewing. These additional menu items allow you to select or deselect the item in order to display or hide the column data in the table.
