Best way to update values for Garbage Collector?

Project Example
I have created a simple project example with some of the configuration I use. Check it and click on Open in New Window to better understand questions.

How to Ease Garbage Collector Job?
In the attached project if we click on More data button:

• Empty old data array
• Set new data array
• Refresh chart

If we analyse the JS memory with devtools and click many times on More data button I can see:

• JS heap is increasing on some clicks. Is there any way to avoid this?
• When garbage collector is launched (after a long time or forcing it with devtools), most of the time the whole memory is released (back to initial situation), but sometimes not and memory increased (memory leak?).

In general, which is the best way to full update datasets[x].data values?

Why Re-Creating a New Chart Does Not Show Properly?
I just tested to destroy and recreate new chart to check if this way memory is handled in a better way. We can achieve this by clicking More data (re-create) button and:

• Chart is destroyed.
• Chart variable is reset.
• Chart is re-created.

But the problem here is that chart is not rendered in the proper way. Any suggestion to fix it?
