Support for Drupal 7 is ending on 5 January 2025—it’s time to migrate to Drupal 10! Learn about the many benefits of Drupal 10 and find migration tools in our resource center.A chart that uses a data-url as data-source now shows "no data to display" (cfr 01.png).
When editing the chart, there seems to be no problem at all with loading the data (02.png) and after saving the chart shows up as it should (03.png).
After a while the data will disappear again.

deanbowles CreditAttribution: deanbowles commentedI am having the same issue ("no data to display" when using url to csv as data source). It was working perfectly at first, but when I revisited the page I received the "no data to display" message. I went back into the configuration, added the url again and saved it, and it started working again. I checked it the next morning and it was gone again.

swentel CreditAttribution: swentel commentedI can't reproduce the disappearing of the data, what I see though is that the chart sometimes doesn't reflect what's in the data after a cron run for instance, but this seems more of a caching issue at highcharts then something else.

jyve CreditAttribution: jyve commentedThe issue indeed appears to be when cron runs. For some unknown reason, the cron run is sometimes not able to fetch the data. In that case it just empties the stored data.
This has been fixed in the latest dev version. If the data cannot be reached, then no updates are done and the existing data is kept.
