create a powerpoint waterfall and Marimekko chart
in the attached images you will find on the type of design that I need to be inserted in the Powerpoint Addin.
This should work for powerpoint 2007-13, windows machine
The way it should work is, when the user selects the graph, the user can then popup a window, displaying the values of the chart. (Check the image flow)
By doing this the user can then make changes to the numbers as required in the popup window as shown in the image. The same logic should be used for Marimekko
Please note that these options should not be limited to the tool, users who do not possess the option, should be able to make changes to the excel behind, but at the same time, if there are any changes in the behind excel and the program cannot detect the default cells / values, the system must display a message
Please note that the project strictly needs to be done in Visual Basic. And as the milestones are complete, code has to be supplied to me, and will have it tested on my personal machine
