Combining Macros, Tables/Charts & Dropdown Menu

I am trying to create a sheet on my workbook, which contains a dropdown menu, containing the titles of a range of graphs and charts, that I need to be able to show. However to show all of the charts and graphs all at once, what I want to be able to do, is select a graph/chart from the dropdown menu, and that particular graph/chart will appear underneath, and all of the graphs can be viewed individually from the dropbown list.

I dont really know what the best way of doing this is, I'm assuming it is to create the charts/graphs on separate sheets, then use some sort of macro code to be able to make one of them appear on the 'Costs Analysis' sheet when the corresponding chart/graph is selected from the dropdown list.

I have attached a copy of my workbook, with the core data, which the graphs are based on (sheet is called 'Costs'), and a graph on each sheet, and then my main sheet called 'Costs Analysis', which I have included a list of all the charts that need linking to the dropdown box.

Feel free to have a fiddle around, and see if its possible, and any replies and solutions will be received with great appreciation.

Thanks in Advance.
