Heatmap Widget

Introduction

Description

The Heatmap widget visualizes aggregated time-series data using a color-coded matrix. Assets are displayed along the Y-axis, while time intervals are plotted on the X-axis. Each cell in the grid represents a data value, with color intensity indicating the magnitude of the metric. This format enables rapid identification of patterns, anomalies, and performance trends across assets over time.

Purpose

The Heatmap Chart is designed to help users quickly assess asset behavior and performance trends in a compact, visual format. It is especially effective for identifying recurring issues, peak activity periods, or gaps in data collection across multiple assets.

Target Audience

• Operations Managers monitoring asset performance over time  

• Maintenance Teams identifying recurring faults or downtime  

• Data Analysts detecting patterns and anomalies in time-series data  

• Business Leaders reviewing asset utilization and operational efficiency  

Key Features & Use Cases

1. Time vs. Asset Visualization

• Feature: Displays assets on the Y-axis and time intervals on the X-axis.

• Use Case: In a BESS facility dashboard, visualize temperature readings across all HVAC units over a 24-hour period to identify units with abnormal heat patterns.

2. Color-Coded Aggregation

• Feature: Uses color intensity to represent aggregated metric values.

• Use Case: In a monthly report, highlight DC input currents across Inverters, with darker shades indicating higher usage.

3. High-Density Data Display

• Feature: Compactly presents large volumes of time-series data.

• Use Case: In a maintenance dashboard, show vibration levels across hundreds of turbines over a week to spot outliers.

Data Types Used

The Heatmap Chart widget typically uses:

• Timestamp: For X-axis time intervals  

• Asset ID or Name: For Y-axis labeling  

• Metric Value: Aggregated and color-coded within each cell (e.g., temperature, energy output, vibration level)  

Widget Use in BI App Types

Dashboard Use Case

In a real-time operations dashboard, the Heatmap Chart displays hourly performance metrics across all assets, helping teams identify sudden changes or recurring issues at a glance.

Report Use Case

In a quarterly asset performance report, the widget visualizes daily utilization patterns across departments, supporting decisions on resource allocation and maintenance scheduling.
