What Are Mosaic Plots?

Mosaic plots, also known as Marimekko charts, are a way to visualize how different groups of data are related to each other. In a mosaic plot, each data group is represented as a different color or shade. The size of each group is proportional to the amount of data in that group. This makes it easy to see which groups are the largest and how they are related. They are similar to bar charts, but the bars are divided into segments representing the proportion of each category’s two variables. Keep reading to learn more about mosaic plots.

What is a mosaic plot?

A mosaic plot is a graphical technique used to display the relationships between categorical variables. The tiles are arranged in a matrix, with the rows and columns representing different variables. Each tile represents a category. The tile size is proportional to the number of observations in that category, and a line is drawn between two tiles if there is at least one observation in both types. Mosaic plots are most useful for visualizing data represented in a table or matrix. They can be used to identify patterns or relationships between variables, and they can be used to compare groups of data.

How do you create a mosaic chart?

A mosaic chart, also known as a linear Marimekko or a stacked area chart, displays data in a way that helps you understand the different parts of the data. A mosaic chart comprises two parts: the diagram itself and the legend.

The mosaic chart is a series of rectangles, with each rectangle representing a data value. The height of the rectangle is proportional to the data point’s value, and the width is proportional to the difference between the data point and the previous data point. The legend is a series of labels placed adjacent to the chart that identifies the data points represented by each rectangle.

In a mosaic chart, the horizontal axis is used to measure different categories, and the vertical axis is used to measure the amount of data in each category.

To create a mosaic chart, you first need to gather data that can be divided into categories. For example, you could collect data on the sales of different products in your store. Once you have your data, you can create a chart in a spreadsheet program like Excel.

  • To create a mosaic chart in Excel, you first need to create a table with the data you want to chart.
  • Next, select the data in the table and use the Insert > Chart > Area > Stacked Area command to create the chart.
  • The chart will be displayed as a series of stacked bars. To change the chart to a mosaic chart, select the chart and use the Design > Switch Row/Column command.
  • The chart will now be displayed as a series of lines. You can use the Format > Series > Line command to change the line color and width.
  • You can also use the Format > Chart > Area command to change the chart area color and fill type.
  • To add data labels to the chart, select the chart and use the Format > Labels > Data command.
  • You can use the Format > Chart > Data command to change the data type, format, and location of the data labels.
  • You can also use the Format > Chart > Axes command to change the axes settings.

A mosaic chart is a powerful tool for measuring performance and visualizing data. Using this chart, you can quickly see how different parts of your data are related and the difference between each data point. Additionally, they are easy to understand since the rectangles are clearly labeled with their corresponding data values.
