|
|
|
|
All Chart.js references have been removed from the project. Search results confirm:

|
|
- No `chart.js` CDN links found
|
|
- All canvas elements for charts have been replaced with div elements
|
|
|
|
## Rollback Instructions
|
|
|
|
If needed, to rollback to Chart.js:
|
|
|
|
1. In `templates/layouts/base.html`, replace:
|
|
```html
|
|
<script src="https://cdn.jsdelivr.net/npm/apexcharts@3.45.1/dist/apexcharts.min.js"></script>
|
|
```
|
|
with:
|
|
```html
|
|
<script src="https://cdn.jsdelivr.net/npm/chart.js@4.4.0/dist/chart.umd.min.js"></script>
|
|
```
|
|
|
|
2. Restore the original Chart.js implementations from git history for:
|
|
- `templates/complaints/analytics.html`
|
|
- `templates/dashboard/command_center.html`
|
|
|
|
## Notes
|
|
|
|
- ApexCharts is loaded globally in the base template, so it's available on all pages
|
|
- No additional dependencies or npm packages required
|
|
- CDN version used for easy deployment and maintenance
|
|
- All chart configurations are inline in the templates for easy customization
|
|
|
|
