Graph ad groups by cost in Adwords

[StalkerB]

Easy one for someone I'm sure, but I can't figure it out.

In Adwords under campaigns "Widget" I have ad groups "Blue", "Green" and "Red" each with 3 ads in them.

How can I produce a compared report on cost per day of each ad group.

So I want something that looks like

1st     2nd   3rd    ...
Blue    £12   £14    £9    ...
Green  £8    £11     £5    ...
Red      £9    £22   £16   ...

Possible?

I don't think it actually is, ive never seen a reporting tool that breaks down cost per day for a whole month. It might be possible to do it in analytics if you got the tracking installed.

If I go into the adgroup I can see the cost by day no problem (just toggle graph options), but I want to do it a level up rather than collate them all individually.

Seems like something that should be possible
