= Purpose =
The purpose of the [[mhttpd]] History Web Page to display data from the [[History System]] in graphical form, giving the user an easy way of seeing how experimental variables have changed with time.
 
 
= Introduction =
The History Page is displayed by clicking on 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;">History</span> button on the mhttpd [[Status Page]]. <br><br>

The History Page takes much of its information from the [[/History ODB tree]].
Figure 1 shows the History Page from the Deap 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.

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.
 
Below, a series of buttons are provided to
* define the time scale of the graph with predefined time window  (e.g. <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;">10m</span> last 10 minutes, <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;">1h</span> last hour etc.)
 
* permit the shifting of the graph in the time direction, i.e. <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;"><<</span> <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;">-</span>
 
* resize the graphs <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;">Large</span> <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;">Small</span>
 
* create an Elog attachment <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;">Elog</span>
 
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.
*    Time scale in date format.
*    Sorting variables
