Value Panel

The Value Panel displays the current value of a single signal in real-time. It's designed for monitoring critical metrics, status indicators, or any signal where you need a prominent, easy-to-read display of the latest value.

Overview

The Value Panel shows one signal's current value in large, centered text. It's perfect for dashboards where you want to highlight key metrics like temperatures, speeds, status codes, or any other important real-time data point.

  • Real-time updates - Displays the latest value as it arrives
  • Enum mapping - Automatically translates numeric codes to meaningful text
  • Customizable options - Scale font visibility and more

Key Features

Using the Value Panel

Adding a Signal

To display a signal in a Value panel:

  1. Add a Value panel - Click "+ Add Panel" and select "Value"
  2. Drag a signal - Drop any signal from the tree onto the panel
  3. View updates - The latest value appears immediately

Value Display Features

Enum Mapping

When signals have associated value tables (enums), the panel automatically translates numeric values to their text representations:

Example mappings:

  • Status code 0 → "OK"
  • Mode value 3 → "AUTO"
  • Error code 255 → "CRITICAL_FAULT"

Data Type Support

The Value panel handles all Zelos data types:

Type Display Example
Integer 42
Float 3.14159
String "Active"
Boolean true or false
Enum RUNNING
Null null

Signal Chip

At the bottom of each Value panel, a signal chip provides:

  • Signal name - Full path or shortened based on settings
  • Data type - Shown on hover (int, float, string, etc.)
  • Quick removal - X button to clear the panel
  • Drag capability - Move signal to other panels

Panel Settings

Access settings through the panel menu (⋮) → "Edit Panel":

Display Options

Panel Title

Set a custom title for the panel. If left empty, the panel shows the signal name as the title.

Display Full Name

Toggle between showing:

  • Full path: robot/sensors.temperature
  • Short name: temperature

This helps balance detail with readability in your workspace.

Font Size

Choose from six text size options

Single Signal Display

Each Value panel displays exactly one signal. To monitor multiple values:

  • Create multiple Value panels
  • Arrange them in a grid layout
  • Save the arrangement as a layout

While Value panels are optimized for real-time display, you can export the current value:

  1. Click the ⋮ menu in the panel header
  2. Select "Export Data"
  3. Choose format (CSV or JSON)

  4. The exported file contains:

    • Current timestamp
    • Signal identifier
