Waffle map

This method represents several stocks in comparable units for each entity in the form of a grid of symbols. For each entity, a set of symbols (of a fixed size) is used to represent the different values according to a predefined ratio (for example, 1 symbol per 1000 units). Each stock variable is represented by a different color.

Layer creation parameters

When creating a layer, you need to select the following parameters:

• Stock variables to be used (minimum 2),
• Symbol type (square or circle),
• The size of each symbol (radius of the circle or size of one side of the square, in pixels),
• Conversion ratio (number of units per symbol),
• The behavior of the grid (fixed number of columns or dynamic number of columns),
• Spacing between each row/column of symbols.

Once the layer has been created, it is possible to modify :

• the color of each stock variable,
• their display order,
• the name of each variable (as it appears in the legend),
• the anchoring (vertical and horizontal) of symbol groups,
• the position of each group of symbols (by moving them with the mouse).
