Issue #5 - [BUG] Bar Chart X-axis time formatting stuck on adaptive mode

[zenocross]

Description

In Bar Charts, when attempting to configure X-axis time formatting, the setting is not applied correctly. The chart always uses "Adaptive" formatting regardless of the user's selected format.

Current Behavior

• User selects specific time format for X-axis (e.g., "%Y-%m-%d")
• Chart saves the configuration
• Chart still renders using Adaptive formatting
• User's time format preference is ignored

Expected Behavior

• User selects desired time format from dropdown
• Chart applies the selected format to X-axis labels
• Time values display in chosen format
• Format persists across chart refreshes

Steps to Reproduce

1. Create a Bar Chart with time series data on X-axis
2. Go to chart configuration
3. Find X-axis time format settings
4. Select a specific format (not "Adaptive")
5. Save and refresh chart
6. Observe X-axis still uses Adaptive formatting

Root Cause

The issue occurs because the X-axis configuration is missing the proper format settings. The chart defaults to Adaptive mode when the configuration is incomplete or not properly passed to the ECharts component.

Proposed Solution

• Ensure X-axis format configuration is properly extracted from chart settings
• Pass format configuration to ECharts options
• Add test cases covering different time format scenarios
• Verify format applies correctly and persists

Technical Context

• Component: Bar Chart (ECharts-based)
• Involves: Chart configuration parsing, ECharts options generation
• Requires: Understanding of ECharts time axis configuration
• Testing: Multiple test cases for different formats needed
