Usage Details
Y_Axis
The Y Axis of the trender is the vertical scale used to indicate the recorded value for a point. Values are marked in increments for Analog values. There are two small arrows ¼ and ¾ of the way up the left hand scale. The lower arrow indicates 0(OFF) for digital points. The upper arrow indicates 1(ON). Digital points will be slightly offset from each other to increase readability. The Y-axis scale is automatically selected during a trend according to the points used in the current pen set. The upper range is the highest upper range of all the points and the lower range is the lowest of all the lower ranges. To manually select the scale, click the Y_Axis button and use one of the following methods
Use Bounds - Insert upper and lower bound. Click Use Bounds. Y axis scale will use this range.

Use % Mode - Click Use % Mode button to have each point displayed as a percentage of its range.

Use Point Scale - Select one of the current pens with slider and click Use Point Scale. That pen’s high and low range will be used as the upper and lower bound of the Y axis.

Use All Pens - Click Use All Pens to use the default method of highest and lowest range among selected points
View Pens
View currently selected pens by clicking View Pens button. This screen shows Point name, pen color and width, Value and Units for selected points. The Value shows the current value when in Real Time mode and shows values at times selected in Historical mode (See Cursor below).
Mode
The Historian uses two modes of operation, Real Time and Historical. Real Time mode gives constantly updated trends from present time to some point in past much like a strip chart. Historical mode allows review of past data. Modes are switched with the Mode button. The Label to the right of the Mode button indicates current mode. The next label to the right is the status indicator.

Edit Pens
This screen permits the user to add, remove or modify pens in current set. Points available for trending will be listed in Point list. Currently selected points are at the top of the list and are preceded by an asterisk (*). All other points are listed in alphabetical order. Select points to add, remove or modify. Up to 32 points may be added to one set.Color and width are also selectable. Click Add to add pen. If point already exists in set,the pen style will be updated. Click Remove to remove pen from set.
Times
This screen allows the user to select the time scale of trends (x-axis). In realtime mode, this selects amount of time shown on screen. In both modes, minimum zoom is 1 minute and maximum is 72 hours.
In Historical mode, exact times may be entered with Start Time and End Time selectors. Times can also be easily entered with Pan and Zoom selectors. Pan indicates movement forward and backward in time. Pan indicator shows amount of movement forward or backward when using Pan buttons. This amount can be increased or decreased with Up/Down selector. Use Zoom In and Zoom Out buttons to increase or decrease the amount of time displayed. Indicator shows span. The Refresh button is then clicked to refresh graph with selected times. Until Refresh button is clicked, Pan and Zoom will use the last times selected with those buttons, not any times entered in selectors. Zoom always work from End Time back. Zoom will not be reflected by times manually selected.

When viewing historical data, it is possible to get accurate indication of times in graph by clicking on the graph. A thick blue line will appear at the point the user clicked.
In the cursor box at top, the time and date for that point will appear. The cursor may be moved left or right by clicking the < and > buttons. Cursor moves one pixel at a time and time is calculated accordingly. Turn cursor off with x button. The values in the View Pens box will reflect the values for each point at that time.
