If you start a new business, create a new product, or change a business model, break-even analysis lets you find out at what stage your company, product, or service will become profitable. Break-even point is the stage where you have no profit yet but have no loss already. However, there are many preceding and following stages important for the investor. The investor wants to know not only how quickly the initial investments will pay off, and extra income will be received, but also how quickly the normal profit and the economic profit will be earned.

A revenue the company generates from selling the products or providing the services should cover the fixed costs, variable costs, and leave a contribution margin. The point where the total operating margin (the difference between the price of the product or service and the variable costs per item or customer) covers the fixed costs is called a break-even point.

Excel pie charts are useful to display fractions of a whole by splitting a circle into sections. Each section looks like a slice of a pie and represents a category. Such a layout makes it easy to observe relationships between parts, but the smaller becomes the slice (less than 10%) – the harder becomes to estimate it visually.

This is the third and last part of the tip How to create a mosaic plot in Excel (the second part is How to create a step Area chart for the Mosaic plot in Excel). The step area chart created in the previous part has invalid labels for both axes and no data labels:

This is a second part of the tip How to create a mosaic plot in Excel. The first part describes how to prepare the data for the step Area chart created in this part.

Pie and bar charts greatly simplify the understanding of percentages distribution for one categorical variable but fail to build a meaningful representation of two and more variables. A quite recent innovation in data visualization real is the Mosaic plot, which helps to grasp the correlations within marketing, sales, and other financial data. You will not find this chart among Excel standard charts, but you can build one.

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. The illustration of multi-market shares and multiple investment portfolios calls for different approaches. The Marimekko chart (also known as Mekko chart, or mosaic plot) comes to the rescue.

A Heatmap or Heat Map chart looks like a table, which cells colors depend on the cell value. These charts are popular in biology, web and other analytics, geography, etc. Tabular data transformation for time series data projects one-dimensional data into two-dimensional time matrices, which simplify frequent pattern analysis.
