The History Page takes much of its information from the [[/History ODB tree]].
Figure 1 shows the History Page from the agmini experiment. This page shows the panels and sub-panels defined in the [[/History ODB tree#<panel-name> subtree|/History/Display subtree]].
 
New panels are added by the user with the <span style="color: #444444; background-color: #CCCCCC; font-style:italic; font-size: 90; padding:0.25em;
padding-left: 0.5em;padding-right: 0.5em;border:1px solid #808080;border-radius: 5px;margin-bottom:1px;">New</span> button (Figure 3).
Up to 10 history channels per page are supported.
<div style="clear: both"></div>  <!-- clear wraparound after thumbnail -->

Figure 3 shows the History display for all the panels in the Group UPSs. One of the panels from the group (i.e. UPS2) is shown in Figure 4.
 
At the top of the History panel display (Figure 4) are drop-down lists of the possible group names and panels defined in the ODB. These are used for navigation among the History plots.

The plots can be manipulated with the following actions:
* through the menu (see right)
* click and drag within the main plot area to pan
* click and drag within an axis to zoom in
 
Configuring the panel is done via the
<span style="color: #444444; background-color: #CCCCCC; font-style:italic; font-size: 90; padding:0.25em;
padding-left: 0.5em;padding-right: 0.5em;border:1px solid #808080;border-radius: 5px;margin-bottom:1px;">Config</span>
button, which displays the Configuration page (Figure 5).
 
The configuration options for a given panel include
*    Zooming capability, run markers, logarithmic scale.
*    custom time frame graph display
*    Data query in time.
