Allied Telesis AlliedView-EMS 3.10 DEVICE MANAGER - Manual (Page 72)

The components of the Plot Chart tab are discussed below.
6.2.1 Graph
The left half of the window contains the graph showing the values of the
selected variables. The vertical (Y) axis shows the values and the horizontal (X)
axis shows time. New values are plotted when Device Manager gets them, at
the predefined polling interval.
The scale of the X-axis is automatically adjusted according to the number of
values plotted. The X-axis can display a maximum of the latest 20 values. The
rightmost point is the most recent.
Each variable is plotted in a different color and shape. A list of the variables on
the graph and their shapes and colors is displayed between the graph and the
variable table.
By placing the mouse cursor on the plotted dot on the graph, you can see the
exact values (coordinates) of the variable. For example, when you move the
cursor onto the 10th point on the X-axis which has a value of 100, the numbers
"(10,100)" are displayed.
6.2.2 MIB Variable Table
The right half of the window is the table of variables suitable for graph display.
Each entry has a checkbox. Only checked variables are plotted on the graph.
Assume that you selected four variables to display. If one of the variables has
very large values, for instance 1000000, and the other variables have low values,
for instance approximately 100, the vertical axis is automatically scaled to
accomodate the largest variable. In this situation, you can see only the largest
variable because the scale of the vertical axis is too large for other three smaller
variables. To see smaller variables, uncheck the largest variable temporarily.
Note - SNMPv3: Depending on the READ VIEW access settings of the User
Account Name used, there is a possibility that some MIB variables will not be
displayed in this table.
6.2.3 Select All Button
: checks all variables. Clicking this button causes all variables to be plotted on
the graph.
6.2.4 Clear Button
: unchecks all variables.
