See this jsfiddle example http://jsfiddle.net/xhoycvsn/21/
1) In this example when you click the ‘run’ button and then ‘reload’ and ‘run’ multiple times the browser memory increases and never releases.
2) Our charts are very dynamic, the user can run a report with any number of charts and then go back and run a different report with completely different charts.
Unfortunately since we are using JSF and a single page the dom does not change. How can we free the memory from previously rendered canvasjs charts?
3) We understand the update() functionality which appends data to existing charts json (which we are already using in other cases), but that solution is not applicable in case this due the reason described in above points.
We have replied to you and your team via mail.
Sanjoy–Having the same issue as Alex, what was the solution to this problem?
We have introduced a new destroy method in v220.127.116.11 which solves this problem. For more details please take a look at this documentation page.
We are facing the same issue, we are using destroy method also, but still increasing memory
we have a dashboard page, it will show dashboard for each level, while switch between levels memory is increasing continuously.
in our application while switching between level we first destroy every existing charts using destroy method, then create new dashboard with charts, but still increasing memory
I recommend you to use the latest version of CanvasJS – v2.2. Please check out our release blog for more information.
If you are still facing the issue in the latest version, kindly provide the browser details and share a JSFiddle reproducing the issue you are facing so that we can understand your scenario better and help you out.

I can confirm v2.3 fixed memory leak https://canvasjs.com/blog/01/25/canvasjs-charts-v2-3ga-released/
First of all, thank you for the great tool that you have developed.
I am a beginner in programming so most likely, it could be something that I am missing.
I am currently using AJAX to pull data from a database and using your Scatter graph to display. It works fine until I use setInterval command to to call the same function that pulls data from database via AJAX call and render the chart again.
The browser crashes after few loops as the browser is consuming too much memory. I have tried using the chart.destory() function, but that didn’t help either.
I tried pasting the code, but it keeps on saying, I have been blocked.
Can you kindly share a sample project reproducing the issue you are facing over Google-Drive or OneDrive so that we can look into your code, run it locally at our end to understand the scenario better and help you out?
