Sudden Change in Display of Charts in the Service - all fields blank fields displayed

[SnoJa10]

So, since the last weekly update, charts in my reports online now suddenly display all fields (even if they contain no values). There are also a lot of (blank) values displayed within the chart.

I'm using Excel Power View in the backend, but previously any dimensions which contain no values would not appear in the chart itself.

What has changed?

I've had to manually filter out blanks as it looked un-readable.

I saw that this behaviour was changed as part of the November update.  I would think you can revert to the prior behaviour by adding filters to exclude blank values.
