Class Graph

java.lang.Object
view.Graph
public class Graph extends Object
Renders a continuously updating line chart onto a JavaFX Canvas.

The graph is used by the simulator UI to visualize a moving stream of numeric values, such as the current mid-price during a simulation run. Internally it keeps a sliding window of the latest values up to maxPoints, redraws the canvas on every JavaFX animation pulse, and paints a background grid plus a formatted price axis.

    • addValue

      public void addValue(double value)
      Appends a new value to the graph.

      If the internal buffer grows beyond maxPoints, the oldest value is discarded so the chart remains a fixed-width sliding window.
