I have a line chart showing data with a strip line to highlight data below a defined limit ( from 0 to 0.05 for example).
Works great.
Creating a copy of this chart and changing the horizontal x axis scale to log 10, the strip lines no longer show.
This article: http://technet.microsoft.com/en-us/library/dd239316(v=sql.110).aspx
suggests that the StripWidth is measured in inches on the report - this is not the case.
