Attached patch patchSplinter Review
This patch the ability to:

1. calculate the std deviation of the data reported to phonedash.
2. optionally display the std deviation on the phonedash graph.
3. optionally only display the first data point.

I'll send you some good example data to host at mcote_bc.

This works well with one exception. When I update the browser and restart when I have the graph displayed with the error bars checked, the page will get into an infinite loop where it continually checks and unchecks the errorbars. This does not happen when starting the browser with a saved session though.

I'm pretty weak on the way forms are handled in phonedash and there is probably something silly I'm doing wrong.

Looks good, just a few nits.

Don't capitalize "Initial".

Would be kind of nice if this didn't result in urls ending in "/undefined".  Makes it looks like there was an error or something.  Maybe $('#errorbars').attr('checked') ? 'checked' : 'off' or something?

Why do we submit the value of #errorbars?  Doesn't look like the API does anything with it...

Standard Python coding style (PEP-8) specifies underscores instead of mixed case for function names.

Move to top so we don't do the import on every call to this function.

I think this would be clearer as count == 1, just because the following line presumes that there is at least one element in values.

Yeah, I had some difficulty with this. I'll try to make it nicer.

I didn't at first, but when I needed to pass the initialonly to the handler, I realized I had left out the ability for the handler to get it. I did it mostly for consistency. We *could* ignore the std dev calculation if we didn't have errorbars checked....

I can take it out if you want.

Oh. I was trying to be consistent with the file, but those are all ClassNames! ok.

It's fine for now, until we rework the UI issues anyway.
