Hi again,

I also try this code https://canvasjs.com/jsp-charts/chart-from-csv-data/

But when I try the content of chart does not appear.

no content on the chart

And this is the following error:

Failed to load https://canvasjs.com/data/gallery/jsp/tuna-production.csv: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8080' is therefore not allowed access.

could you please help me, why this happen?
