eazyBI specifies any data represnetation per represenatative metric.
In some cases, the representative metric consists of a combination of some member name and measure. This typically is the case when you are using several measures in Columns and you have a dimension expanded to member names on Columns as well.
If the dimension used on Columns is used on Pages as well, leading to the case, when you change the pages - column members changes. Then represenative metrics in report might be different for some combinations.
In those reports, it might be hard to set it up every time you change the Pages, columns selections changes as well. I would suggest selecting the chart type (Bar, or Line (Line can work as area as well)) to get the required formatting by default. Change the formatting for static metrics only.
