Saiku Analytics charts

Hello there again.

I have a few questions regarding Saiku Analytics community edition query tool. I have made few charts with it and the only reason I am using it and not using the CCC charts is because you can go deeper on your charts with Saiku Analytics.
Anyhow, my problem is that Saiku Analytics Legend text is awful at the moment and I would like to ask if it is possible to edit that legend in any how?

First of all I would like to turn that text maybe from vertical to horizontal, or not, I do not yet know. And is it possible to modify that text in somehow like let's say to form of "201308,201309" without modifying the data in database?
I know I can set the visibility of this legend to none, but it really does not serve the purpose of the legend and the chart after that.

I would like to ask also is this "drilling" or selecting from chart possible to do in CCC charts like in Saiku Analytics charts?:
