What do you mean by easy way?
I mean that I want to find the correct color code / alignment style and other formatting options in order to have best visualization. Default setting are not good enough.
Not really sure there is a "best visualization" as it's extremely subjective (can't count anymore the number of customers loving their 15 years old rainbow style reports).
For colors there is a page Oracle did that I find useful: http://www.oracle.com/webfolder/ux/middleware/alta_icon_web_design_guide/colors-icon_palette.html
You have some set of colors (and their hexa code) that match quite good for charts.
