TheWitness Report post Posted June 2, 2021 After refreshing a chart by using a dispose() method followed by redefining and recreating the fusionchart I'm getting the following warning when hovering or moving the cursor over the 'updated' chart.: Uncaught TypeError: this._env is undefined This is on line 13 of fusioncharts.js This is for version 3.15.2. Seems that the function is falsely assuming that the value exists. So, there are no bounds checking going on. Share this post Link to post Share on other sites

If you are still getting the problem please share your usecase scenario that you are using so that we could check accordingly. Share this post Link to post Share on other sites
