Our first stop in the new page wizard requires us to choose a data source (historical archive or real time) and a display format (alphanumeric or graph). NOTE: Because alphanumeric pages only show a single value for each point, the Next button will be unavailable if you try to use a historical archive as the data source for an alphanumeric page. |
 |
In this panel we specify the time window and data resolution of the data we wish to see. The resolutions offered represent each of the different DARS recorders running in the main computer room. The available data time range will be updated as the sample resolution is changed, but the actual times are estimated, based on the defined size of the [circular] archive recorder files.
When specifying the start/stop times, you may select a calendar date/time or enter a relative time. A relative start time specifies an offset from the stop time. A relative stop time specifies an offset from the time the page is created (you may use zero or 'now' for the current time). Relative times are specified using a shorthand notation, e.g. 2h 30m represents 2 hours and 30 minutes. The legitimate letters are d:day, h:hour, m:minute, and s:second. |

This panel selects the graph type (notice that bar graphs have not yet been implemented). The panel includes a short description of each graph type available |
 |
Here we are selecting the layout for a STRIP graph and the total time duration for horizontal axis. A Discrete strip graph has a separate strip for each of the points being graphed. The composite and overlay graphs combine all of the ANALOG points into a single strip and keep the digitals in discrete strips (located above the single analog strip). A Composite strip takes the largest and smallest of the vertical axis limits from all of the analogs combined and plots all tracks against the new axis. An Overlay strip plots each analog against its own vertical axis within the same physical space. The currently selected point (identified by a box around the point's legend/value) has its vertical scale displayed. |
 |
Here we select the method used for connecting the data samples on a single strip. The descriptions of each connection type are shown in the selection panel.
We also choose which of the optional graph elements are to be included. For HISTORICAL graphs, it is strongly suggested that the titles be enabled because ReDisp automatically sets the SubTitle to show the historical time frame displayed on the graph. |
 |
Strip graphs are currently limited to 12 points. This was done to reduce the clutter caused by too many tracks being drawn in the same space. The 'Add Blank' button will be disabled in this panel for graphs because a blank strip would be meaningless. Also, while you are allowed to adjust the point sequence here, be aware that the graph engine will collect all of the digital points to the top of the list and all of the analogs to the bottom. It will otherwise attempt to retain your original order, but that is not guaranteed. |
 |
This is the actual point selection dialog. It allows you to specifiy a specific building and unit whose points you want to select. The selected point list includes a count (in this case (4) is the count) to help you know when you're reaching the limit for a particular page type. Alpha pages are limited to 50 and graphs are limited to 12 points each. |
 |
OK, now that you've chosen the points you want to see, all you need to do is press finish to have recall display subscribe to the data and start displaying it for you. The reason for this step is to provide a last chance to use the Back button to move backward through the wizard to make any corrections that might be necessary. |
