New issue 44 by molly.ba...@tridsys.com: Memory leak when frequently
updating line graph
https://code.google.com/p/elycharts/issues/detail?id=44

Running ELYCHARTS v2.1.5 on a Windows 7 OS

Starting with the line graph that is used as an example on the webpage, I
made little modification except to have a fill underneath one of three
lines.

I update the graph and call $("#chart").chart('clear'); and then issue the
drawChart command every .5 seconds to have the webpage update with current
values of the data.

The lines each have 10 points. Two of the lines maintain constant values
for their data to show "thresholds." I am really only concerned with
updating the data for the third line.

When I run this program, it appears to have a bit of a problem hogging the
processor and the values from the graph lag behind the values that are sent
to the webpage, and it becomes very slow after about 11-12 minutes. The
page is very slow then and will eventually become entirely unresponsive.

Any thoughts on what I can do to release memory or somehow more gracefully
produce a graph that changes as time passes?

Thank you.

Are you experiencing the same issue with every browser?
(Firefox/Chrome/IE/Safari)

Can you create a jsbin/jsfiddle to reproduce the issue?

Have you tried to call chart without "clearing" every time?

I removed the reference to tooltips and it seems to be running faster.

When I tried to call chart without "clearing" every time, it went much,
much slower.

I do not know that tooltips solved my problem, but at least I am not having
the problem anymore. If it happens again and I have more details, I will
update.
