hillfallshore Report post Posted October 15, 2012 (edited) The javascript function of "clearChart" does not work properly while no feeding data. In my scenario, I want to grab the data from db every hour, and when i click the "clear" button, the chart will be cleared. Because the date interval is so long, while I clicking the "clear" button and trigger the "clearChart" function, it will be no feeding data at the moment. In this scenario, the chart will become a blankboard, and the data will not display in the chart though the feeding data is not null from then. I think it should be a bug. thanks and forgive my poor English. Edited October 15, 2012 by hillfallshore Share this post Link to post Share on other sites
