Combination Chart: Bars and TreeMap with VBA

Excel Version
  1. 2016
Excel presents a wide variety of charts, but not a hybrid of bars and tree maps. It is not necessary to write code for custom tree maps because a guy named Fabrice Rimlinger already did that when creating the add-in mentioned below.

His source code is not protected so you can look at it after installing the add-in. Here are the main features of my code:

  • Uses tables as a data source, one of them is shown beneath. The addresses used for this example were: B70:C81, B83:C94, B96:C111, B113:C130, B132:C143 and B145:C180
  • Creates the bars from ordinary shapes and tree maps produced by the add-in.
  • Defines colours as arrays of integers.
  • Writes intermediary pictures to disk.
