Line graph visualization bug?

[Fran_Fabrizio]

Thanks, that does solve this problem. Unfortunately, it leads me to
another problem, where my data values were changing unexpectedly when I add
buckets, which I describe in a separate post here:

Confused about interaction between unique count and buckets

Let's say I set my time range to be 2013-01-01 00:00:00.000 to 2013-01-31 23:59:59.999 (entire month of January 2013). Then I do a line graph visualization and keep the default y-axis setup which is a count of _all documents in my index in that time range, it produces 1,565 hits. (just a dot at 1,565, since I haven't defined an x-axis). One of the fields in my documents is user_id. If I then change the y-axis to do a Count of user_id in that same time period, I get 1,565 hits. So far, nothi…

Thanks again. I'm glad that reordering the buckets solved the graphing
bug, at least!
