Options in the Height tab
The following table shows the options under
Expression.
Options | Description |
|---|---|
Expression | Specify a tag name or an expression that will evaluate to numeric values at runtime. An expression is a mathematical or logical equation that returns a value. It can contain tag names; constants; mathematical, relational, logical and bitwise operators; and built-in alarms and events functions. A tag name can be used as an expression. |
The following table shows the options under
Expression range
.Options | Description |
|---|---|
Use tag's min and max property values | If you have specified a tag in the Expression box, click this button to use the tag's minimum and maximum values to define the range of values for the expression. This option only applies to tags for which minimum and maximum can be defined, such as HMI tags. |
Use constant | To use constant numeric values to define a range of values, click this button and specify values for minimum and maximum. |
Read from tags | To define the range of values using one tag's value for the minimum and another tag's value for the maximum, click this button and then specify a tag for minimum and another for maximum. Using this option, when the animation for an object is started, the tags' values are read once to set the minimum and maximum values. The tags are not read again after, nor are the minimum and maximum values changed. |
The following table shows the options under
Vertical change (Percent)
.Options | Description |
|---|---|
At minimum | The height of an object when it is selected is the base size (100 percent). Type the height the object is to be when the expression evaluates to its minimum value. This is a percentage of its base size. You can also grab the top handle of the object and drag until it is the correct minimum height, then check the box beside At Minimum. |
At maximum | Specify the height the object is to be when the expression evaluates to its maximum value. This is a percentage of its base size. You can also grab the top handle of the object and drag until it is the desired maximum height, then check the box beside At Maximum. |
The following table shows the options under
Anchor
.Options | Description |
|---|---|
Anchor | Anchor determines which part of the object remains constant. |
Top | Click this if the top position of the object is to remain constant. As the value of the expression changes, the object grows to or shrinks from the bottom. |
Middle | Click this if the midpoint of the object is to remain constant. As the value of the expression changes, the object lengthens and shortens equally on either side of its midpoint. |
Bottom | Click this if the bottom position of the object is to remain constant. As the value of the expression changes, the object grows to or shrinks from the top. |
