Reporting Services - Expanding a Chart Subreport

I had a subreport with a chart, but i did not like how it was drawn because it was displayed with the chart and some legends at its right side, so that the chart width was decreased so as to the legends could be seen expanded.

I prefered to see all the chart on the same size so that i go to the report designer and on the chart properties , at the Legend tab i modified it to write the legends with row layout centered at bottom.
