•
Zero Origin - This option draws the selected axis including the origin
(zero) and extending far enough in the positive and negative directions to
include all of the graph’s values
•
Variable Origin - Select this option to have the axis “zoom in” on the
range of the graph’s actual values, whether or not that range includes
zero.
•
User-Defined - This option allows the user to set values for the minimum,
maximum, and number of ticks for the axis. When this option is selected,
the settings in the Range group are enabled
By default, the X-axis and Y-axis are both set to Variable Origin.
Note: Changing the Scale settings (especially for the X-axis) while ac
-
quiring real-time data could possibly cause graphing problems to occur.
Therefore, it is recommended that these settings NOT be changed by the
user when acquiring real-time data.
The Range options are only enabled if the User-Defined option is selected in
the Scale options for the selected axis. Enter the Maximum and Minimum val-
ues for the selected axis. The selected axis is rescaled to the settings entered.
The Ticks option allows the user to determine how many major tick marks
should be displayed between the minimum and maximum values on the se-
lected axis. Each major tick mark is labeled with the appropriate value. The tick
marks themselves are only displayed if the Show check box in the Tick Marks
controls is checked.
By default, these settings are not used by the software because of the default
Scale settings.
The Tick Marks options allow the user to specify whether or not to show tick
marks on the selected axis. To show tick marks, check the Show check box. If
this check box is not checked, the tick marks are not shown on the selected
axis. Valid settings are between 1 and 1,000.
The Every option is only enabled for the X-axis. This option determines how
often major tick marks appear on the X-axis. When acquiring real-time data,
the graph displays the most recent 600 readings acquired. The Every option is
set to 150 meaning that a major tick mark appears every 150 readings, or 600
divided by 150 = 4 major tick marks appear on the X-axis. When analyzing
previously acquired data, the Every option is calculated by the software de
-
pending on the number of readings being displayed. The X-axis must end with
a tick mark. If you set an Every value that doesn’t include the last value on the
axis, the graph will extend the X-axis so that it ends on a tick mark.
The Minor option allows the user to determine how many minor tick marks ap
-
pear between each major tick mark. By default, the X-axis and Y-axis are set to
display 5 minor tick marks between major tick marks. Valid settings are be
-
tween 0 and 100.
