Reduce white space between the PlotArea and the Walls of the chart

Is it possible to reduce the white space surrounding the walls of the chart. (i.e. the region between the walls of the chart and the Plot Area)?

to be more precise, is there any property or method to 'AutoScale' the chart to the Plot area?

When a chart is created, the plot area is auto scaled.

Could you please post a sample file here to elaborate your need?
