Chart Examples

This guide showcases the different chart configurations available through the tibber_prices.get_apexcharts_yaml action.

Quick Start: Call the action with your desired parameters, copy the generated YAML, and paste it into your Lovelace dashboard!

Overview

The integration can generate 4 different chart modes, each optimized for specific use cases:

ModeDescriptionBest ForDependencies
TodayStatic 24h view of today's pricesQuick daily overviewApexCharts Card
TomorrowStatic 24h view of tomorrow's pricesPlanning tomorrowApexCharts Card
Rolling WindowDynamic 48h view (today+tomorrow or yesterday+today)Always-current overviewApexCharts + Config Template Card
Rolling Window Auto-ZoomDynamic view that zooms in as day progressesReal-time focus on remaining dayApexCharts + Config Template Card

Screenshots available for:

  • ✅ Today (static) - Representative of all fixed day views
  • ✅ Rolling Window - Shows dynamic Y-axis scaling
  • ✅ Rolling Window Auto-Zoom - Shows progressive zoom effect

All Chart Modes

1. Today's Prices (Static)

When to use: Simple daily price overview, no dynamic updates needed.

Dependencies: ApexCharts Card only

Generate:

service: tibber_prices.get_apexcharts_yaml
data:
entry_id: YOUR_ENTRY_ID
day: today
level_type: rating_level
highlight_best_price: true

Screenshot:

Today's Prices - Static 24h View

Key Features:

  • ✅ Color-coded price levels (LOW, NORMAL, HIGH)
  • ✅ Best price period highlights (vertical bands)
  • ✅ Static 24-hour view (00:00 - 23:59)
  • ✅ Works with ApexCharts Card alone

Note: Tomorrow view (day: tomorrow) works identically to Today view, just showing tomorrow's data. All fixed day views (yesterday/today/tomorrow) use the same visualization approach.


2. Rolling 48h Window (Dynamic)

When to use: Always-current view that automatically switches between yesterday+today and today+tomorrow.

Dependencies: ApexCharts Card + Config Template Card

Generate:

service: tibber_prices.get_apexcharts_yaml
data:
entry_id: YOUR_ENTRY_ID
# Omit 'day' for rolling window
level_type: rating_level
highlight_best_price: true

Screenshot:

Rolling 48h Window with Dynamic Y-Axis Scaling

Key Features:

  • Dynamic Y-axis scaling via chart_metadata sensor
  • ✅ Automatic data selection: today+tomorrow (when available) or yesterday+today
  • ✅ Always shows 48 hours of data
  • ✅ Updates automatically when tomorrow's data arrives
  • ✅ Color gradients for visual appeal

How it works:

  • Before ~13:00: Shows yesterday + today
  • After ~13:00: Shows today + tomorrow
  • Y-axis automatically adjusts to data range for optimal visualization

3. Rolling Window Auto-Zoom (Dynamic)

When to use: Real-time focus on remaining day - progressively zooms in as day advances.

Dependencies: ApexCharts Card + Config Template Card

Generate:

service: tibber_prices.get_apexcharts_yaml
data:
entry_id: YOUR_ENTRY_ID
day: rolling_window_autozoom
level_type: rating_level
highlight_best_price: true

Screenshot:

Rolling Window Auto-Zoom - Progressive Zoom Effect

Key Features:

  • Progressive zoom: Graph span decreases every 15 minutes
  • Dynamic Y-axis scaling via chart_metadata sensor
  • ✅ Always shows: 2 hours lookback + remaining time until midnight
  • ✅ Perfect for real-time price monitoring
  • ✅ Example: At 18:00, shows 16:00 → 00:00 (8h window)

How it works:

  • 00:00: Shows full 48h window (same as rolling window)
  • 06:00: Shows 04:00 → midnight (20h window)
  • 12:00: Shows 10:00 → midnight (14h window)
  • 18:00: Shows 16:00 → midnight (8h window)
  • 23:45: Shows 21:45 → midnight (2.25h window)

This creates a "zooming in" effect that focuses on the most relevant remaining time.


Comparison: Level Type Options

Rating Level (3 series)

Based on your personal price thresholds (configured in Options Flow):

  • LOW (Green): Below your "cheap" threshold
  • NORMAL (Blue): Between thresholds
  • HIGH (Red): Above your "expensive" threshold

Best for: Personal decision-making based on your budget

Level (5 series)

Based on absolute price ranges (calculated from daily min/max):

  • VERY_CHEAP (Dark Green): Bottom 20%
  • CHEAP (Light Green): 20-40%
  • NORMAL (Blue): 40-60%
  • EXPENSIVE (Orange): 60-80%
  • VERY_EXPENSIVE (Red): Top 20%

Best for: Objective price distribution visualization


Dynamic Y-Axis Scaling

Rolling window modes (2 & 3) automatically integrate with the chart_metadata sensor for optimal visualization:

Without chart_metadata sensor (disabled):

┌─────────────────────┐
│ │ ← Lots of empty space
│ ___ │
│ ___/ \___ │
│_/ \_ │
├─────────────────────┤
0 100 ct

With chart_metadata sensor (enabled):

┌─────────────────────┐
│ ___ │ ← Y-axis fitted to data
│ ___/ \___ │
│_/ \_ │
├─────────────────────┤
18 28 ct ← Optimal range

Requirements:

  • ✅ The sensor.tibber_home_chart_metadata must be enabled (it's enabled by default!)
  • ✅ That's it! The generated YAML automatically uses the sensor for dynamic scaling

Important: Do NOT disable the chart_metadata sensor if you want optimal Y-axis scaling in rolling window modes!

Note: Fixed day views (today, tomorrow) use ApexCharts' built-in auto-scaling and don't require the metadata sensor.


Best Price Period Highlights

When highlight_best_price: true, vertical bands overlay the chart showing detected best price periods:

Example:

Price

30│ ┌─────────┐ Normal prices
│ │ │
25│ ▓▓▓▓▓▓│ │ ← Best price period (shaded)
│ ▓▓▓▓▓▓│ │
20│─────▓▓▓▓▓▓│─────────│
│ ▓▓▓▓▓▓
└─────────────────────── Time
06:00 12:00 18:00

Features:

  • Automatic detection based on your configuration (see Period Calculation Guide)
  • Tooltip shows "Best Price Period" label
  • Only appears when periods are configured and detected
  • Can be disabled with highlight_best_price: false

Prerequisites

Required for All Modes

  • ApexCharts Card: Core visualization library
    # Install via HACS
    HACS → Frontend → Search "ApexCharts Card" → Download

Required for Rolling Window Modes Only

  • Config Template Card: Enables dynamic configuration
    # Install via HACS
    HACS → Frontend → Search "Config Template Card" → Download

Note: Fixed day views (today, tomorrow) work with ApexCharts Card alone!


Tips & Tricks

Customizing Colors

Edit the colors array in the generated YAML:

apex_config:
colors:
- "#00FF00" # Change LOW/VERY_CHEAP color
- "#0000FF" # Change NORMAL color
- "#FF0000" # Change HIGH/VERY_EXPENSIVE color

Changing Chart Height

Add to the card configuration:

type: custom:apexcharts-card
graph_span: 48h
header:
show: true
title: My Custom Title
apex_config:
chart:
height: 400 # Adjust height in pixels

Combining with Other Cards

Wrap in a vertical stack for dashboard integration:

type: vertical-stack
cards:
- type: entity
entity: sensor.tibber_home_current_interval_price
- type: custom:apexcharts-card
# ... generated chart config
