What you are looking for is 2-D Bar Graph. You can add legends using legend.

x = [3 4;1.5 1.75;0.25 0.3];
bar(x,'hist');
legend('PZT','MFC');
set(gca,'xticklabel',{'20Hz','30Hz','40Hz'});
This code will produce bar graph like the attached image. gca will select the current axes and then you could specify the xticklabel for the bar graph.

I suggest you take a look at the MATLAB Plot Gallery, which has examples of lots of plot types, along with the code that produces them. This may save you time asking about everything small addition that you want, one at a time.
