A Marimekko chart (sometimes also called mekko chart or market share chart) is a two-dimensional stacked chart. In addition to the varying segment heights of a regular stacked chart, a Marimekko chart also has varying column widths.Column widths are scaled such that the total width matches the desired chart width. To preserve the visual relationship between widths of different columns, there are no gaps between columns in a Marimekko chart. The y-axis in the Marimekko chart shows the percentage scale. However, the x-axis shows the relationship between the sums of values within categories, varying the column width. This chart is primarily used for marketing analysis and sales data.
