Fixing Dynamically Updating Chart.js Issue

I'm in need of a developer who can help me fix an issue I'm experiencing with my ajax call in a Chart.js project. The problem specifically is that the chart is not updating dynamically.

Key Requirements:
- Fix the ajax call issue so the chart updates dynamically
- Ensure the chart works flawlessly in browsers such as Google Chrome, Mozilla Firefox, and Safari

Additional Info:
- There's a need for the chart to have an ability to filter data.

Ideal Experience:
- Strong knowledge of Chart.js
- Proficiency in AJAX, JavaScript, and web development
- Prior experience in similar projects where you've managed to achieve dynamic data updates on a chart
- Understanding of cross-browser compatibility

Feel free to ask me any questions or for any clarifications you might need. Looking forward to working together on this!
