PI Vision Custom Symbol : CUSTOM RADIAL GAUGE

Description

The PI Vision custom symbol Custom Radial Gauge is a single datasource symbol that behaves similarly to the native symbol Radial Gauge, and also displays colored sectors and marks, to highlight the datasource limits :

• Minimum
• Lowest limit (LoLo)
• Low limit (Lo)
• High limit (Hi)
• Highest limit (HiHi)
• Maximum
• Target

Example :

This symbol will easily integrate to your existing PI Vision displays : everywhere you have a Radial Gauge, you can replace it by a Custom Radial Gauge and show useful limits.

For sure, this will significantly improve the user experience.

The Custom Radial Gauge is compatible with PI Points and PI AF Attributes as well.

In fact, with all data types that support limits :

• Byte
• Int16
• Int32
• Int64
• Single
• Double
  

Features

All features of the native radial gauge are available in the Custom Radial Gauge.

Moreover, this symbols displays 5 colored sectors, and a target mark near to the value indicator and the scale range.

Those new elements are fully customizable (colors, sizes, show or hide, etc...).

For example, the size of the sectors can be set for all types of indicators :

Moreover, you can set the values of the limits manually (fixed limits), or retreive dynamically the limits of a PI AF (attribute limits).

Configuration options

In the configuration panel, you can find all the same options as the native Radial Gauge, plus 3 new option groups : "Limits", "Target" and "Borders".

• Limits

  

  • Show Limit Sectors : you can choose to show the limit sectors or not.
    If you disable this feature, the symbol will look exactly the same as the native Radial Gauge

  • Even give some of them a transparent background
