Color_threshold Totally Off When Sensor Data Is Missing

by ADMIN 56 views

Introduction

The color threshold feature in the custom:apexcharts-card is designed to display different colors based on specific threshold values. However, when sensor data is missing, the color threshold becomes totally off, resulting in incorrect color representation. This article aims to provide a detailed explanation of the issue, its reproduction steps, and the expected behavior.

Checklist

Before diving into the issue, it's essential to ensure that all necessary steps have been taken to troubleshoot the problem.

  • Updated Card Version: The card has been updated to the latest version available.
