X-Axis Values and Font Size

I have a chart showing Month dimension as shown below.. Current view shows month like 01/2013  ,,,,

I have requirement to show Text like Jan 2013 ,,but when i change property , I lose horizontal values becasue of size of the font,,,, CAn i control size of x-axis values so i could see values.

As YOU SEE X-Axis is gone,, IT is if i could have control on font size of X-Axis, IT might show up,, Pleaseadvise how can i control font size of x-axix lables and hover over values....

Thanks
