  • All Implemented Interfaces:
    Dataset, Identifiable
    Direct Known Subclasses:
    AbstractBoundedPlot

    • Constructor Detail

      • AbstractPlot

        public AbstractPlot​(OTSSimulatorInterface simulator,
                    java.lang.String caption,
                    Duration updateInterval,
                    Duration delay)
        Constructor.
        Parameters:
        simulator - OTSSimulatorInterface; simulator
        caption - String; caption
        updateInterval - Duration; regular update interval (simulation time)
        delay - Duration; amount of time that chart runs behind simulation to prevent gaps in the charted data

    • Method Detail

      • setChart

        protected void setChart​(JFreeChart chart)
        Sets the chart and adds menus and listeners.
        Parameters:
        chart - JFreeChart; chart

      • encodeAsPng

        public byte[] encodeAsPng​(int width,
                          int height,
                          double fontSize)
                   throws java.io.IOException
        Returns the chart as a byte array representing a png image.
        Parameters:
        width - int; width
        height - int; height
        fontSize - double; font size (16 is the original on screen size)
        Returns:
        byte[]; the chart as a byte array representing a png image
        Throws:
        java.io.IOException - on IO exception

      • setAutoBoundDomain

        public void setAutoBoundDomain​(XYPlot plot)
        Overridable; activates auto bounds on domain axis from user input. This class does not force the use of XYPlots, but the auto bounds command comes from the ChartPanel that this class creates. In case the used plot is a XYPlot, this method is then invoked. Sub classes with auto domain bounds that work with an XYPlot should implement this. The method is not abstract as the use of XYPlot is not obligated.
        Parameters:
        plot - XYPlot; plot

      • setAutoBoundRange

        public void setAutoBoundRange​(XYPlot plot)
        Overridable; activates auto bounds on range axis from user input. This class does not force the use of XYPlots, but the auto bounds command comes from the ChartPanel that this class creates. In case the used plot is a XYPlot, this method is then invoked. Sub classes with auto range bounds that work with an XYPlot should implement this. The method is not abstract as the use of XYPlot is not obligated.
        Parameters:
        plot - XYPlot; plot

      • getGraphType

        public abstract GraphType getGraphType()
        Return the graph type for transceiver.
        Returns:
        GraphType; the graph type.

      • getStatusLabel

        public abstract java.lang.String getStatusLabel​(double domainValue,
                                                double rangeValue)
        Returns the status label when the mouse is over the given location.
        Parameters:
        domainValue - double; domain value (x-axis)
        rangeValue - double; range value (y-axis)
