Radar Chart+

Overview

Radar Chart+ compares several attributes across one or more AF assets on a common radial scale.

When to use it

Use this symbol when you need to:

• Compare an asset's multivariable profile with peers or a reference.
• Show relative strengths and deviations across several measures.

Before you begin

• Prepare comparable AF assets based on a common element template.
• Choose compatible ranges or normalize attributes that use different units.

Add and set up the symbol

1. Select the symbol in the PI Vision symbol gallery.
2. Add the required data sources or asset context to the display.
3. Right-click the symbol and open its configuration pane.
4. Configure the minimum data, range, and display settings for a useful result.
5. Confirm that the symbol shows the expected data.

Use the symbol

Select an asset or hover over a point to compare its profile and exact value with the other series.

Overview and behavior

Radar Chart+ is a custom symbol that visualizes multiple process values across units or assets using a polar (spider) chart. Ideal for comparing equipment performance or highlighting anomalies, Radar Chart+ supports dynamic data labels, multi-state styling, and auto-generated axes based on asset search criteria.

Configuring selectable assets

Populate Radar Chart+ with either a static asset list or a dynamic asset search. For a static list, drag the required assets onto the symbol and set an optional custom label for each asset under Assets.

Dynamic Assets

In Order to dynamically load assets, right-click the control and select Add Dynamic Search Criteria…

	=>

In the search criteria pane on the right side, you are now able to search and filter for your assets.

The Search Criteria supports the following options:

• Database
• Search Root
• Asset Name
• Asset Type
• Asset Category
• Number of Results
• Asset Order

Click Refresh to update the assets in the control. If you are not seeing the assets you are filtering for, make sure to set the Return All Descendents in the Search Root as well as check the Number of Results.

Static Assets

If Dynamic Asset Search Criteria is not used, and the assets are configured manually, you can additionally configure the following properties for the assets.

• Label: Change the name of the asset

Additionally, if the scale category type is set to Attribute (meaning the Assets are the series/legend items) the following options are available to be configured for assets.

• Color: The series color
• Symbol (Type/Size): Change the symbol appearance for each node
• Line (Style/Width/Opacity): Change the appearance of the connecting lines

Important: These options are only available if Dynamic Asset Search Criteria is NOT used.

Configuring the scale

The most important part when configuring the Radar Chart+ is the type of category that you want to use for the scale. So essentially, you can choose to have your Assets or your Attributes as the Edges and Series.

If you set the Category Type to Asset, your assets will be shown on the edges, and each attribute is a series, or legend item.

On the other hand, if you set the Category type to Attribute, the attributes will be shown on the edges, and each asset is a series or legend item.

Below you can see the same symbol, with the Category Type changed.

Category Type Asset Category Type Attribute

Additionally, the following configuration options are available.

• Labels: Show/Hide the category labels
• Clockwise: Whether to order the assets/attributes clock-wise or counter clock-wise
• Start: The start angle of the Radar Chart
• Scale Range: Choose between auto, custom and individual. The range applies to all assets and attributes on the radar chart. The individual option is only available if the category type is set to attribute, allowing you to individually configure the scale range for each attribute.

General configuration

Title

Configure the title of the chart, and change it’s position and styling.

• Title: Enable / Disable Title
• Input: The actual title of the chart
• Position: The position of the title, choose between Left / Center / Right
• Font Size: The font size of the title

Style

Configure the basic styling options for the Radar Chart.

• Foreground: The text color
• Background: The symbols background color
• Font size: The font size
• Shape: Choose between Polygon and Circle. Polygon will draw straight lines between the edges, whereas circle will draw curved lines.

Legend

The position and alignment of the charts legend.

Series

This section is available if Dynamic Search Criteria is used and the Scales Category Type is set to Attribute. It allows the global configuration of the markers and lines:

• Symbol (Type/Size): Change the symbol appearance for each node
• Line (Style/Width/Opacity): Change the appearance of the connecting lines

Asset configuration

If Dynamic Search Criteria is not used, this section allows the configuration of settings for individual assets.

• Label: Change the name of the asset

Additionally, if the scale category type is set to Attribute (meaning the Assets are the series/legend items) the following options are available to be configured for assets.

• Color: The series color
• Symbol (Type/Size): Change the symbol appearance for each node
• Line (Style/Width/Opacity): Change the appearance of the connecting lines

Attribute configuration

In this section, you can add and remove attributes to the chart, as well as configured individual attributes settings.

• Value: Change the value type for that attribute. Choose between the current value, minimum, maximum, average, standard deviation and count.

The following options are only available if the Scale’s Category Type is set to Asset:

• Color: The series color
• Symbol (Type/Size): Change the symbol appearance for each node
• Line (Style/Width/Opacity): Change the appearance of the connecting lines

Troubleshooting and limitations

• Check: If an asset or attribute is missing, check the search criteria and template mapping.
• Check: A shared scale can be misleading when attributes use incompatible units or ranges.
