Re: Update series.data in bar-chart

Hi, Great observation! In the earlier solution, I omitted the id property to simplify the example, focusing on resolving the immediate issue. However, if you rely on the id property for your data points, you can include it in your updates. Here's how you can update the remove method to include the i...
