public class Mean extends AbstractView<LineGraph> implements AbstractGraph.Shifter, AbstractGraph.Zoomer
A view that displays time-series plots of mean trait values or mean fitness for the current EvoLudo model using one or more LineGraph panels.

Responsibilities

  • Create and manage the set of LineGraph panels appropriate for the current model configuration (one panel per discrete species, or one panel per continuous trait when the model is continuous).
  • Configure visual style for each graph (labels, y-range, colors, markers) depending on whether the data represents TRAIT or FITNESS and whether the underlying model is continuous or discrete.
  • Collect mean values from the model and push them to the graphs on updates; supports both mean +/- standard deviation (continuous) and per-trait frequencies/mean payoffs (discrete).
  • Manage zooming and shifting of displayed window of time series data.
  • Handle layout, sizing and resetting of graphs when model settings change.

Exports

Supports exporting graphs as SVG and PNG as well as exporting the mean time series data as CSV).

      public Mean(EvoLudoGWT engine, Data type)
      Construct a new view to display the time series data of the current EvoLudo model.
      Parameters:
      engine - the pacemaker for running the model
      type - the type of data to display

  • Method Details

    • getName

      public String getName()
      Description copied from class: AbstractView
      Get the name of this view. This is used to dynamically build the view selector.
      Specified by:
      getName in class AbstractView<LineGraph>
      Returns:
      the name of this view

    • allocateGraphs

      protected boolean allocateGraphs()
      Description copied from class: AbstractView
      Allocate all graphs managed by this view. This is called when loading the view. Once all views are attached to the browser DOM a call to the graph's calcBounds(int, int) is triggered through setBounds(int, int) to properly calculate the layout.
      Specified by:
      allocateGraphs in class AbstractView<LineGraph>
      Returns:
      true if graphs were (re)allocated

    • addLineGraph

      private void addLineGraph(Module<?> module)
      Create and register the LineGraph(s) for a single module: one graph for the module, and additional graphs for extra traits when the model is continuous.

      module - module for which graphs should be created

    • reset

      public void reset(boolean hard)

      hard - the flag to indicate whether to do a hard reset
