This example demonstrates an interactive XY line chart that visualizes multivariate data arrays, mapping X, Y, and Z coordinates while allowing users to apply range filters to specific data columns. The implementation uses Scala with JavaFX collections (FXCollections) for managing dynamic filter lists and processing data through custom variable handling. The visualization relies on the OpenMOLE framework's Variable and VariableData APIs to concatenate streaming data arrays. Filtering operations transpose the data table and apply minimum/maximum bounds to selected columns, producing filtered arrays for rendering. The example also uses spray.json for JSON serialization of coordinate data with color assignments.
