Use the following code. You replace your data with DataY.

figure ('Position', [293,243,900,420]);

DataX = (20:30:620)';

DataY = [
	2.5		1.6
	3.0		2.0
	3.5		2.2
	3.6		2.3
	4		2.5
	4.3		2.7
	4.2		2.6
	2.5		1.6
	3.0		2.0
	3.5		2.2
	3.6		2.3
	4		2.5
	4.3		2.7
	4.2		2.6
	2.5		1.6
	3.0		2.0
	3.5		2.2
	3.6		2.3
	4		2.5
	4.3		2.7
	4.2		2.6
	];

BarChart = bar (DataX, DataY);

xticks (DataX);

set (BarChart, {'FaceColor'}, {[0,0,1];[1,1,0]});
