I successfully created bar charts using vue2 and vue-chart.js with data from an API call. However, I am facing issues with displaying line charts. Despite loading the data, the line chart is not showing up, and no errors are being displayed. I have reviewed my code but cannot identify the error. Any suggestions? Thanks!
