Quadrant Chart

I have 4 separate bar graphs that I want to take and combine into one chart. The thing is, it has been requested that they are shown in quadrants. So, I don't want to combine the data, I just want to show the charts all together.

So, chart one would be in the upper left-hand corner, chart two would be in the upper right-hand corner, chart three would be in the lower left-hand corner, and chart four would be in the lower right-hand corner.

Is there a way to do this?
