# 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.
