Mapmost Studio mapping supports expressions, which are based on data-driven styles. Allows spatial data to be dynamically styled based on its properties. Expressions allow data to be styled simultaneously through multiple feature attributes, conditional logic, and data manipulation through arithmetic and string operations to create more complex relationships between the data and how it is styled.
The expression uses Mapmost's special language, reference website:

Expression module example:

There is an expression icon
next to all configuration items, indicating that this configuration item can support expressions and can be switched to expressions at any time. The attributes of spatial data can be set through statements to dynamically set the style of spatial data.
