ADEI provides sophisticated Google-maps style web interface. The short video displaying basic functionality could be obtained from [http://csa.aragats.am/ADEI.mpeg here].

== Selecting Data ==
Click on ''Data Source'' button and submenu providing data/time configuration options will be opened. There is two tabs: ''Source'' and ''Axis'':
 * The ''Source'' tab allows to select appropriate data source and data channels to display. ADEI implements hierarchical addressing. The data channels are grouped in so called ''LogGroups''. All channels within single ''LogGroup'' are time-synchronized and can be displayed on a single graph. To select ''LogGroup'', one needs to choose ''Server'' and ''Database'' where the 'LogGroup' is stored - it is not necessarily real server and database but rather a way of logically structuring data belonging to different components/experiments/etc. After the desired ''LogGroup'' is selected an user is able to choose which data channels he/she is interested in. It is possible to display all group channels at once, select a single channel from the list, or choose from several predefined channel masks. After clicking ''Apply'' button the data from the selected channels will be aggregated and displayed on the graph.
 * By default all available data is aggregated and displayed on the graph. Using ''Axis'' tab it is possible to display the data only for desired time period. When choosing fixed length ''Windows'', like ''1 Year'', ''1 Weak'', etc., the data for the last specified interval, i.e. for the last year, will be aggregated and displayed. The ''Custom'' window will allow to specify exact start and stop of desired time interval. As well it is possible to limit range of values displayed on Y-axis. However, in most cases it is easier to use dynamic navigation system described in next section.

Toy can visualize time-series for rather long period (years) and then select defiinite time span and zoom it by simple righ cliccking.

== Navigation ==
The data navigation is trying to follow Google-Maps standards:
 * To get more detailed graph of certain data currently on display, ''zoom-in'',the select appropriate region (press and hold left mouse button while moving mouse pointer) and, then, click on the arrow or double click in the center of selection. Both ''Time'' and ''Y'' axis could be zoomed. To zoom only over ''Time''-axis select with mouse narrow horizontal line. Correspondingly, to zoom only over ''Y''-axis the narrow vertical line should be selected.
 * The mouse wheel could be used for zooming in and out on the ''Time''-axis. Scroll down to zoom-out and up to zoom-in.
 * Double clicking on ''Y''-axis (actually gray area left from the ''Y''-axis) will remove any ''Y''-zooming and the ''Y''-axis will be auto-adapted to accommodate whole data range.
 * Double clicking on ''Time''-axis (actually gray area bellow the ''Time''-axis) will revert to default display mode when all available data aggregated and presented on the graph.
 * Scrolling mouse wheel on the ''Time'' or ''Y'' axis will shift currently displayed data window along the corresponding axis.
 * It is possible to use key modifiers to adjust mouse actions. Please, click and hold ''h'' key to get short help on the supported keys. 
  * For example, holding ''z'' key and single-clicking left mouse button will perform ''Deep Zoom'' on ''Time''-axis and show detailed graph displaying the data around the clicked point. 
  * Clicking left mouse button while ''c'' key is held will result in centering (''Time''-axis) around current mouse position.
  * Another example is zooming with mouse wheel: by default the ''Time''-zooming is performed at the current mouse pointer. If you press ''c'' key is pressed while zooming-in, the zoom will be performed at the center of currently displayed graph.
  * As well it is possible to switch channels, data sources and etc. using key modifiers and mouse wheel.

== Legend ==
 * The status bar displays actual position of current mouse cursor.

== Saving interested 

You can go back and forward in history and the current URL completely describes the data on display. Therefore, you can copy URL and store it or send to collegue and exectly the same plot will be displayed.


== Data Export ==

== Search ==
To be implemented and described


== Aggregation and Reporting Invalid Data ==


1. by simple mouse operation you can directly download the desired interval of time-series for the further analysis with sophysiticated codes (for example Exel).
