High CPU usage with C3

[ryankicks]

After I load a C3 chart using the below code, it seems to be taking up a lot of CPU usage. It all stems from the c3.generate() call.

I'm assuming the library is looking for browser resize/interaction updates. (Screen shot attached, where in Chrome the tag is constantly being updated/scanned.)

In my case, I only need to draw the chart but not do anything else. (I do have a lot of data points to work with.)

Is there a way to improve performance, perhaps by disabling this C3 behavior?

This is possibly a duplicate of #926, but unless you're calling generate() a lot, it's probably a separate issue.

Clearly there's something wrong with how C3's listening to the resize event. We really need to create a task force to troubleshoot the current spate of performance issues before they get any worse. See Google Group discussion.

Any suggestions and/or pull requests you can offer are very welcome.

@ryankicks Sorry for the late response. I think resize_auto = false can be used. This option was introduced by this PR #860 and it's still rc version (0.4.11-rc2), but it will be release shortly.

@masayuki0812 resize_auto = false doesn't work. In the "loadConfig" function, the key is splitted by "_" and the "find" function don't find the "resize" so it keeps the "true" value of the default config.
