Step 7. Configure the X or Y-axis Limits

  1. Select the Mode under X-Item or Y-Item in which the axis limits will perform during runtime.

Mode

Defines an axis where the:

apAxisAutoscaled

Low and high limits change to fit all the data values of all the series that use the axis.

The increment used on the high limit is based on the decimal base of the largest series data value.

The decrement used on the low limit is based on the decimal base of the smallest series data value.

If the largest data value increments between 1 and 9, the high limit increments in single digits because the decimal base is 1.

When the value reaches 10, the limit increments in double digits, 10, 20 ,30, etc. When the value reaches 100, the limit incrments in triple digits, 100, 200, 300, etc. The same principle works for the low limit.

apAxisFixed

Low and high limits are fixed. They do not change regardless of the values of all the series that use the axis. This means that only those data values that fall between the fixed limits are displayed.

apAxisScrolled

High limit is set to the maximum data value of all the series plus the scroll percent of the original axis width. The low limit is set to the high limit minus the original axis width. The original axis width is the initial high limit minus the initial low limit. This mode is very useful for incremental flow data.

  1. Specify the High and Low Limits. During runtime, the limits will display in response to the mode you specified. The defaults are:

High

100

Low

0

  1. If apAxisScrolled is selected, configure the Backward and Forward scroll buttons.

  1. Click the to the left of BackwardScroll under X–Item or Y–Item.

  2. Specify whether or not to display the Full Backward Scroll button when the X-axis is in the Forward direction.

  1. Click the to the left of Full.

  2. Set Visible to TRUE to display the button, False to hide the button.

  1. Specify whether or not to display the Partial Backward Scroll button when the X-axis is in the Forward direction.

  1. Click the to the left of Partial.

  2. Set Visible to TRUE to display the button, False to hide the button.

  1. Specify whether or not to display the Full Forward Scroll button,
    when the X-axis is in the Forward direction.

  1. Click the to the left of Full.

  2. Set Visible to TRUE to display the button, False to hide the button.

  1. Specify whether or not to display the Partial Forward Scroll button when the X-axis is in the Forward direction.

  1. Click the to the left of Partial.

  2. Set Visible to TRUE to display the button, False to hide the button.
