# 7 Graphs

#### Overview

In the *Monitoring → Graphs* section any [custom
graph](/manual/config/visualisation/graphs/custom) that has been
configured can be displayed.

To display a graph, select the host group, host and then the graph from
the dropdowns to the right.

*Note*: In the host dropdown, a disabled host is highlighted in red.
Graphs for disabled hosts are accessible starting with Zabbix 2.2.0.

**Time period selector**

The filter section above the graph contains a time period selector. It
allows you to select the desired time period easily.

The slider within the selector can be dragged back and forth, as well as
resized, effectively changing the time period displayed. Links on the
left hand side allow to choose some often-used predefined periods (above
the slider area) and move them back and forth in time (below the slider
area). The dates on the right hand side actually work as links, popping
up a calendar and allowing to set a specific start/end time.

The **fixed/dynamic** link in the lower right hand corner has the
following effects:

-   controls whether the time period is kept constant when you change
    the start/end time in the calendar popup.
-   when *fixed*, time moving controls (<< 6m 1m 7d 1d 12h 1h | 1h
    12h 1d 7d 1m 6m >>) will move the slider, while not changing
    its size, whereas when *dynamic*, the control used will enlarge the
    slider in the respective direction.
-   when *fixed*, pressing the larger **<** and **>** buttons will
    move the slider, while not changing its size, whereas when
    *dynamic*, **<** and **>** will enlarge the slider in the
    respective direction. The slider will move by the amount of its
    size, so, for example, if it is one month, it will move by a month;
    whereas the slider will enlarge by 1 day.

Another way of controlling the displayed time is to highlight an area in
the graph with the left mouse button. The graph will zoom into the
highlighted area once you release the left mouse button.

**Controls**

Three control buttons are available in the title bar:

-   ![](../../../../../assets/en/manual/web_interface/frontend_sections/monitoring/add_to_fav.png) -
    add graph to the favourites widget in the [Dashboard](dashboard)
-   ![](../../../../../assets/en/manual/web_interface/frontend_sections/monitoring/reset.png) -
    reset graph display to the original setting of displaying the last
    hour data
-   ![](../../../../../assets/en/manual/web_interface/frontend_sections/monitoring/full_window.png) -
    use the full browser window to display the graph
