DiagHistogram

public DiagHistogram()

Method Detail

paintComponent

protected void paintComponent(java.awt.Graphics g)

Draw the histogram or cumulative distribution based on the current data. This method is called by Swing whenever Swing feels the diagram needs repainting.

Overrides:

paintComponent in class javax.swing.JComponent

genSVGCode

protected java.lang.StringBuffer genSVGCode(int width,
                                            int height)

Description copied from class: sdmetrics.app.DiagPanel

Create the contents of the SVG file.

Specified by:

genSVGCode in class sdmetrics.app.DiagPanel

Parameters:

width - Width of the graph to generate.

height - Height of the graph to generate.

Returns:

The SVG code to go between the /lt;svg> tags of the resulting SVG file.

newData

public void newData(DescStats ds,
                    int table,
                    int met)

Register new data with this graph display. The method retrieves the metric data sorted in ascending order from a DescStats object.

Parameters:

ds - Object from which to obtain the metric data.

table - Index of the table that contains the metric to display.

met - Index of the metric to display.

setCumulative

public void setCumulative(boolean b)

Determine whether to draw the cumulative distribution or histogram. The graph will instantly be redrawn as per the new setting.

Parameters:

b - true if the cumulative graph is to be drawn, else false

isGraphAvailable

public boolean isGraphAvailable()

Test if the component currently has data available from which it can draw a graph.

Returns:

true if a graph can be drawn based on the current data, else false.

drawSVG

public java.lang.String drawSVG(int width,
                                int height)

Get the SVG code to draw the current graph.

Parameters:

width - Width of the graph to generate.

height - Height of the graph to generate.

Returns:

String with the SVG code (<svg>...</svg>) for the graph.

drawImage

public void drawImage(java.awt.image.BufferedImage bufferedImage)

Draws the current graph into a specified image.

Parameters:

bufferedImage - Image to draw into.
