An explanation of the Symbol Control for Axiom.

Symbol

Over 3800 symbol graphics are available for designing dashboards and HMI screens. The symbol picker will open when the symbol control is added to the screen or “Choose Symbol” is clicked.

Name – The name used by the application and script to reference this control.

X – Number of pixels from the left edge of the containing panel or screen.

Y – Number of pixels from the top edge of the containing panel or screen.

Width – Width of the control in pixels.

Height – Height of the control in pixels.

SymbolSource- Click "Choose Symbol..." to display the Symbol Picker dialog.

Symbols are separated into groups to help choose from the 1000s of symbols.

SourceTag - Clicking the trend icon launches the tag browser to select a tag for

value input. Clicking the trash can will delete the reference to the tag.

Assigning a tag to a symbol allows the designer to set limits which can change the

color of the symbol.

LimitLow - The SourceTag value falling below this value will change the color to

the LimitLowColor.

LimitHigh - The SourceTag value going above this value will change the color to

the LimitHighColor.

Color- The normal color of the symbol. Pick from the color picker or enter the

hexadecimal value.

LimitLowColor - The color of the symbol when the SourceTag value drops below

the LimitLow value. Pick from the color picker or enter the hexadecimal value.

LimitHighColor - The color of the symbol when the SourceTag value goes above

the LimitHigh value. Pick from the color picker or enter the hexadecimal value.

FlipHorizontal - Flips the symbol over from right to left.

FlipVertical - Flips the image upside down.

Rotation - Rotates the symbol clockwise by degrees.

Stretch - Will determine how the symbol fills the control box

• Fill - will stretch the symbol in both direction to fill the size of the control box.
• Uniform - will stretch but maintain the aspect ratio until the symbol reaches either edge of the control box.

Visible - Unchecking this will hide the control. A script would be required to toggle

the visibility during runtime.

OnClick - An event that occurs when the control is clicked. Clicking "<>" Creates a

"Symbol7_Click()" script stub for this control and opens the script editor to add

event scripting. Clicking the trash can will delete only the reference to the script,

not the script.

OnValueChange - An event that occurs when the SourceTag value changes.

Clicking "<>" Creates a "Symbol7_ValueChange()" script stub for this control and

opens the script editor to add event scripting. Clicking the trash can will delete

only the reference to the script, not the script.
