An **Euler diagram** is an effective tool for visualizing the relationships and intersections among three option groups. It consists of circles or ellipses, each representing a set, with overlapping areas showing the elements that the sets have in common.

The maximum number of options that can be used in an Euler diagram is three. If you have more options in a crosstab before selecting the Euler chart, the first three options will be chosen automatically.

## The Euler diagram settings

**Chart Style**:**Rows/Columns**: Similar to other chart types, you can choose which dimension -rows or columns - will be used. Depending on your selection, the other dimension will remain in the category tree submenu. Here you can choose the first three options from which row or column to display and switch between them.**Logic Symbol**: By default, the intersection symbol (∩) is used in the Euler legend. However, you can customize this by entering any word or symbol in the logic symbol field.

**Series Colors:**To enhance clarity, you can use different colors for each of the three main segments. The intersecting segments will be colored to closely resemble a blend of the primary colors, with adjustments made for attractiveness and contrast. However, the color of intersecting segments cannot be manually set.
