Topic: Chart Destroy / Dispose / and Clear Canvas

edharris4 priority asked 1 month ago


As attempting to update initialized pie and doughnut charts which have the percentage values displayed on the chart causes an error as in my previous post, I am attempting to code a temporary-workaround by destroying and disposing of the chart instances and clearing the canvas so that I can put a new chart on the same canvas with the same chart type that would have had the new updated data.

However, trying doughnutInstance.destroy() , doughnutInstance.dispose(), and doughnutInstance.clear() does not work. There was a similar question already asked 3 weeks ago by another user and a solution was posted, but that link no longer exists as it seems to have been removed.

The link for the snippet still gives a 404 error that the link is not found just as it did in the thread 3 weeks ago.
