This is the third, last part of the tip How to create a Marimekko or Mekko chart in Excel (the second part is How to add separators to the Marimekko chart). The area chart created in the previous part needs data labels:

This is the second part of the tip How to create a Marimekko or Mekko chart in Excel. In the first part of this tip, a step Area chart was created:

The distribution of market shares or stocks of the investment portfolio often is illustrated by pie or doughnut charts.
