Memory leak coming from vector 'iniFonts' in Graph.java

[jworkorg]

Sorry, I forgot to mention that every plots we display (every 1m30s) is displayed in the same HPlot canvas. Data is put in P1D objects and added to the first graph in a HPlot graph. Previous data is removed prior to adding.

In my HPlot wrapper, I have a font object that I use for every fonts needed by Graph:

Code:

public static final Font GRAPH_FONT = new Font(null, Font.PLAIN, 10);

At my display window initialization, I configure my HPlot correctly to match my needs. The internalPlotWindow object is my HPlot.

Code:

//Configure the display og the plot canvas.
        this.getInternalPlotWindow().setAttResizableAll(false);
        this.getInternalPlotWindow().setAxesRatioUse(false);
        this.getInternalPlotWindow().setBox(false);
        this.getInternalPlotWindow().setAutoRange(true);
        this.getInternalPlotWindow().setGrid(true);
        this.getInternalPlotWindow().setMarginSizeLeft(0.0);
        this.getInternalPlotWindow().setMarginSizeTop(0.0);
        this.getInternalPlotWindow().setMarginSizeRight(0.0);
        this.getInternalPlotWindow().setMarginSizeBottom(0.0);
        this.getInternalPlotWindow().setPenWidthAxis(1.0);
        this.getInternalPlotWindow().setTicFont(GRAPH_FONT);
        this.getInternalPlotWindow().setLegendFont(GRAPH_FONT);
        this.getInternalPlotWindow().setTicsMirror(false);
        this.getInternalPlotWindow().setTics(true);
        this.getInternalPlotWindow().setAxisPenTicWidth(1);
        this.getInternalPlotWindow().setNumberOfTics(true);
        this.getInternalPlotWindow().setNumberOfTics(Axis.X_AXIS, 10);
        this.getInternalPlotWindow().setNumberOfTics(Axis.Y_AXIS, 10);

        //Add the listeners to the graph for display functions
        this.getInternalPlotWindow().getJPlot().getGraph().addMouseWheelListener(th​is);
        this.getInternalPlotWindow().getJPlot().getGraph().addMouseListener(this);
        this.getInternalPlotWindow().getJPlot().getGraph().addMouseMotionListener(t​his);
        this.getInternalPlotWindow().getJPlot().getGraph().addKeyListener(this);
        this.getInternalPlotWindow().getJPlot().getGraph().setFocusable(true);
        this.getInternalPlotWindow().getJPlot().getGraph().requestFocusInWindow();

        this.getInternalPlotWindow().getJPlot().getGraph().addFocusListener(new FocusListener(){
            public void focusGained(FocusEvent e) {}
            public void focusLost(FocusEvent e) {
                //internalPlotWindow.getJPlot().getGraph().requestFocusInWindow();
            }
        });

When I add a plot to the graph, I do things that way:

Code:

this.getInternalPlotWindow().draw(newItem.getPlot());//getPlot() returns a P1D object of 16384 data points
   this.getInternalPlotWindow().setNameX(newItem.getCurrentEntry().getXunits().getU​nits(), GRAPH_FONT);
   this.getInternalPlotWindow().setNameY(newItem.getCurrentEntry().getYunits().getU​nits(), GRAPH_FONT);

And when I need to remove 1 of them, I cal the clearData() function of HPlot, then re-call the draw(P1D) method for the remaining plots I need to plot.
