I have a chart which is first of all initialized to no data. When a long-running ajax call completes, my code then sets the data on the chart.

This has stopped working with version 2024.4.1112.

If a chart has been initialized with no data, calling refresh has no effect, even after it has been given data.

If a chart has been initialized with data, calling refresh still works.
