        void addXTick​(java.lang.String label,
              double position)
        Specify a tick mark for the X axis. The label given is placed on the axis at the position given by position. If this is called once or more, automatic generation of tick marks is disabled. The tick mark will appear only if it is within the X range.

        Note that if setXLog(boolean) has been called, then the position value should be in log units. So, addXTick("1K", 3) will display the string 

        1K
        at the 1000 mark.
        Parameters:
        label - The label for the tick mark.
        position - The position on the X axis.

              double position)
        Specify a tick mark for the Y axis. The label given is placed on the axis at the position given by position. If this is called once or more, automatic generation of tick marks is disabled. The tick mark will appear only if it is within the Y range.

        Note that if setYLog(boolean) has been called, then the position value should be in log units. So, addYTick("1K", 3) will display the string 

        1K
        at the 1000 mark.
        Parameters:
        label - The label for the tick mark.
        position - The position on the Y axis.

      • clear

        void clear​(boolean axes)
        If the argument is true, clear the axes. I.e., set all parameters controlling the axes to their initial conditions. For the change to take effect, call repaint(). If the argument is false, do nothing.

      • clearLegends

        void clearLegends()
        Clear all legends. This will show up on the next redraw.

      • deferIfNecessary

        void deferIfNecessary​(java.lang.Runnable action)
        If this method is called in the event thread, then simply execute the specified action. Otherwise, if there are already deferred actions, then add the specified one to the list. Otherwise, create a list of deferred actions, if necessary, and request that the list be processed in the event dispatch thread. Note that it does not work nearly as well to simply schedule the action yourself on the event thread because if there are a large number of actions, then the event thread will not be able to keep up. By grouping these actions, we avoid this problem. This method is not , so the caller should be.
        Parameters:
        action - The Runnable object to execute.

      • destroy

        void destroy()
        Destroy the plotter. This method is usually called by PlotApplet.destroy(). It does various cleanups to reduce memory usage.

      • fillPlot

        void fillPlot()
        Rescale so that the data that is currently plotted just fits. This is done based on the protected variables _xBottom, _xTop, _yBottom, and _yTop. It is up to derived classes to ensure that variables are valid. This method calls repaint(), which eventually causes the display to be updated.

      • getColor

        boolean getColor()
        Return whether the plot uses color.
        Returns:
        True if the plot uses color.

        Parameters:
        dataset - The dataset index.

      • renameLegend

        void renameLegend​(int dataset,
                  java.lang.String newName)
        Rename a legend.
        Parameters:
        dataset - The dataset of the legend to be renamed. If there is no dataset with this value, then nothing happens.
        newName - The new name of legend.
        See Also:
        addLegend(int, String)

      • repaint

        void repaint()
        Repaint the object.

      • resetAxes

        void resetAxes()
        Reset the X and Y axes to the ranges that were first specified using setXRange() and setYRange(). If these methods have not been called, then reset to the default ranges. This method calls repaint(), which eventually causes the display to be updated.

      • samplePlot

        void samplePlot()
        Do nothing in this base class. Derived classes might want to override this class to give an example of their use.

      • setAutomaticRescale

        void setAutomaticRescale​(boolean automaticRescale)
        Set automatic rescale. Automatic rescaling is enabled when automaticRescale equals true and disabled when automaticRescale equals false.
        Parameters:
        automaticRescale - The boolean that specifies whether plots should be automatic rescaled.

      • setBackground

        void setBackground​(java.lang.Object background)
        Set the background color.
        Parameters:
        background - The background color.

      • setButtons

        void setButtons​(boolean visible)
        If the argument is true, make a fill button visible at the upper right. This button auto-scales the plot. NOTE: The button may infringe on the title space, if the title is long. In an application, it is preferable to provide a menu with the fill command. This way, when printing the plot, the printed plot will not have a spurious button. Thus, this method should be used only by applets, which normally do not have menus. This method should only be called from within the event dispatch thread, since it interacts with swing.
        Parameters:
        visible - If true, make the fill button appear.
        See Also:

        getColor()

      • setColors

        void setColors​(java.lang.Object[] colors)
        Set the point colors. Note that the default colors have been carefully selected to maximize readability and that it is easy to use colors that result in a very ugly plot.
        Parameters:
        colors - Array of colors to use in succession for data sets.
        See Also:
        getColors()

      • setGrid

        void setGrid​(boolean grid)
        Control whether the grid is drawn.
        Parameters:
        grid - If true, a grid is drawn.
        See Also:
        getGrid()

      • setLabelFont

        void setLabelFont​(java.lang.String name)
        Set the label font, which is used for axis labels and legend labels. The font names understood are those understood by java.awt.Font.decode().
        Parameters:
        name - A font name.

      • setPlotRectangle

        void setPlotRectangle​(java.lang.Object rectangle)
        Set the plot rectangle inside the axes. This method can be used to create two plots that share the same axes.
        Parameters:
        rectangle - Rectangle space inside axes.
        See Also:
        getPlotRectangle()

      • setSize

        void setSize​(int width,
             int height)
        Set the size of the plot. This overrides the base class to make it work. In particular, it records the specified size so that getMinimumSize() and getPreferredSize() return the specified value. However, it only works if the plot is placed in its own JPanel. This is because the JPanel asks the contained component for its preferred size before determining the size of the panel. If the plot is placed directly in the content pane of a JApplet, then, mysteriously, this method has no effect.
        Parameters:
        width - The width, in pixels.
        height - The height, in pixels.

      • setTimedRepaint

        void setTimedRepaint​(boolean timedRepaint)
        Set repainting with a certain fixed refresh rate. This timed repainting is enabled when timedRepaint equals true and disabled when timedRepaint equals false.
        Parameters:
        timedRepaint - The boolean that specifies whether repainting should happen with a certain fixed refresh rate.

      • setTitle

        void setTitle​(java.lang.String title)
        Set the title of the graph.
        Parameters:
        title - The title.
        See Also:
        getTitle()

      • setTitleFont

        void setTitleFont​(java.lang.String name)
        Set the title font. The font names understood are those understood by java.awt.Font.decode().
        Parameters:
        name - A font name.

      • setWrap

        void setWrap​(boolean wrap)
        Specify whether the X axis is wrapped. If it is, then X values that are out of range are remapped to be in range using modulo arithmetic. The X range is determined by the most recent call to setXRange() (or the most recent zoom). If the X range has not been set, then use the default X range, or if data has been plotted, then the current fill range.
        Parameters:
        wrap - If true, wrapping of the X axis is enabled.

      • setXLabel

        void setXLabel​(java.lang.String label)
        Set the label for the X (horizontal) axis.
        Parameters:
        label - The label.
        See Also:
        getXLabel()

      • setXLog

        void setXLog​(boolean xlog)
        Specify whether the X axis is drawn with a logarithmic scale. If you would like to have the X axis drawn with a logarithmic axis, then setXLog(true) should be called before adding any data points.
        Parameters:
        xlog - If true, logarithmic axis is used.
        See Also:
        getXLog()

      • setXRange

        void setXRange​(double min,
               double max)
        Set the X (horizontal) range of the plot. If this is not done explicitly, then the range is computed automatically from data available when the plot is drawn. If min and max are identical, then the range is arbitrarily spread by 1.

        Note that if setXLog(boolean) has been called, then the min and max values should be in log units.

        Parameters:
        min - The left extent of the range.
        max - The right extent of the range.
        See Also:
        getXRange()

      • setYLabel

        void setYLabel​(java.lang.String label)
        Set the label for the Y (vertical) axis.
        Parameters:
        label - The label.
        See Also:
        getYLabel()

      • setYLog

        void setYLog​(boolean ylog)
        Specify whether the Y axis is drawn with a logarithmic scale. If you would like to have the Y axis drawn with a logarithmic axis, then setYLog(true) should be called before adding any data points.
        Parameters:
        ylog - If true, logarithmic axis is used.
        See Also:
        getYLog()

      • setYRange

        void setYRange​(double min,
               double max)
        Set the Y (vertical) range of the plot. If this is not done explicitly, then the range is computed automatically from data available when the plot is drawn. If min and max are identical, then the range is arbitrarily spread by 0.1.

        Note that if setYLog(boolean) has been called, then the min and max values should be in log units.

        Parameters:
        min - The bottom extent of the range.
        max - The top extent of the range.
        See Also:
        getYRange()

      • write

        void write​(java.io.OutputStream out)
        Write the current data and plot configuration to the specified stream in PlotML syntax. PlotML is an XML extension for plot data. The written information is standalone, in that it includes the DTD (document type definition). This makes is somewhat verbose. To get smaller files, use the two argument version of write(). The output is buffered, and is flushed and closed before exiting. Derived classes should override writeFormat and writeData rather than this method.
        Parameters:
        out - An output stream.

      • write

        void write​(java.io.OutputStream out,
           java.lang.String dtd)
        Write the current data and plot configuration to the specified stream in PlotML syntax. PlotML is an XML scheme for plot data. The URL (relative or absolute) for the DTD is given as the second argument. If that argument is null, then the PlotML PUBLIC DTD is referenced, resulting in a file that can be read by a PlotML parser without any external file references, as long as that parser has local access to the DTD. The output is buffered, and is flushed and closed before exiting. Derived classes should override writeFormat and writeData rather than this method.
        Parameters:
        out - An output stream.
        dtd - The reference (URL) for the DTD, or null to use the PUBLIC DTD.

      • write

        void write​(java.io.Writer out,
           java.lang.String dtd)
        Write the current data and plot configuration to the specified stream in PlotML syntax. PlotML is an XML scheme for plot data. The URL (relative or absolute) for the DTD is given as the second argument. If that argument is null, then the PlotML PUBLIC DTD is referenced, resulting in a file that can be read by a PlotML parser without any external file references, as long as that parser has local access to the DTD. The output is buffered, and is flushed before exiting.
        Parameters:
        out - An output writer.
        dtd - The reference (URL) for the DTD, or null to use the PUBLIC DTD.

      • writeData

        void writeData​(java.io.PrintWriter output)
        Write plot data information to the specified output stream in PlotML. In this base class, there is no data to write, so this method returns without doing anything.
        Parameters:
        output - A buffered print writer.

      • writeFormat

        void writeFormat​(java.io.PrintWriter output)
        Write plot format information to the specified output stream in PlotML. Derived classes should override this method to first call the parent class method, then add whatever additional format information they wish to add to the stream.
        Parameters:
        output - A buffered print writer.

      • writeOldSyntax

        @Deprecated
void writeOldSyntax​(java.io.OutputStream out)
        Deprecated.
        Write the current data and plot configuration to the specified stream in the old PtPlot syntax. The output is buffered, and is flushed and closed before exiting. Derived classes should override _writeOldSyntax() rather than this method.
        Parameters:
        out - An output stream.

      • zoom

        void zoom​(double lowx,
          double lowy,
          double highx,
          double highy)
        Zoom in or out to the specified rectangle. This method calls repaint().
        Parameters:
        lowx - The low end of the new X range.
        lowy - The low end of the new Y range.
        highx - The high end of the new X range.
        highy - The high end of the new Y range.
