Examples of ptolemy.plot.Plot.clear()

ptolemy.plot.Plot.clear()

Clear the plot of all data points. If the argument is true, then reset all parameters to their initial conditions, including the persistence, plotting format, and axes formats. For the change to take effect, you must call repaint(). @param format If true, clear the format controls as well.

In order to work well with swing and be thread safe, this method actually defers execution to the event dispatch thread, where all user interface actions are performed. Thus, the clear will not be executed immediately (unless you call this method from within the event dispatch thread). All the methods that do this deferring coordinate so that they are executed in the order that you called them.

            _dataInputStream = new DataInputStream(in);
            _sound = new Audio(_dataInputStream);


            // Configure the plot.
            Plot plt = (Plot) plot;
            plt.clear(true);
            plt.setXRange(0, (_sound.size - 1) / 8000.0);
            plt.setXLabel("Time in seconds");
            plt.setYRange(-1.0, 1.0);


            double[] pltdata = _sound.toDouble(0);

        leftPlot.setSize(350, 300);


        File file = new File(".", "data.plt");


        try {
            rightPlot.clear(true);
            rightPlot.read(new FileInputStream(file));
        } catch (FileNotFoundException ex) {
            System.err.println("File not found: " + file + " : " + ex);
        } catch (IOException ex) {
            System.err.println("Error reading input: " + file + " : " + ex);
