Constructor Detail

GEVAGraph

public GEVAGraph(JSci.awt.Graph2DModel model)

Method Detail

dataChanged

public void dataChanged(JSci.awt.GraphDataEvent event)

Specified by:

dataChanged in interface JSci.awt.GraphDataListener

Overrides:

dataChanged in class JSci.swing.JGraph2D

offscreenPaint

protected void offscreenPaint(java.awt.Graphics graphics)

Overrides:

offscreenPaint in class JSci.swing.JGraph2D

drawData

protected void drawData(java.awt.Graphics graphics)

Overrides:

drawData in class JSci.swing.JGraph2D

getX

protected int getX(float x)

Convert from data x to screen x

Parameters:

x - data x

Returns:

screen x

getY

protected int getY(float y)

Convert from data y to screen y

Parameters:

y - data y

Returns:

screen y

setXExtremaSafe

public void setXExtremaSafe(float minimum,
                            float maximum)

Helper for setXExtrema to prevent illegal values being passed

Parameters:

minimum -

maximum -

setYExtremaSafe

public void setYExtremaSafe(float minimum,
                            float maximum)

Helper for setYExtrema to prevent illegal values being passed

Parameters:

minimum -

maximum -

drawXLabel

protected void drawXLabel(java.awt.Graphics graphics,
                          double value,
                          java.awt.Point point)

X labels are being packed together too tightly, overlapping each other. This only renders every second label to space them out

Overrides:

drawXLabel in class JSci.swing.JGraph2D

Parameters:

graphics -

value -

point -

calcSeriesValueAt

public float calcSeriesValueAt(int seriesIndex,
                               int screenX)

Calculate the value of the data for a series at a particular mouse location on the graph. This is 'calculate', rather than 'get', as a single pixel can cover several data points; this returns the average of all points under the specified point

Parameters:

seriesIndex - Index of the series whose value is to be calculated

screenX - The x point in pixels of the data value to calculate

Returns:

The average of all the data points under the screen X

getDataIndexAt

public float getDataIndexAt(int screenX)

Get the data index at a screen coordinate relative to the graph. This is the value of the x axis on the graph

getDataValueAt

public float getDataValueAt(int screenY)

Get the data value at a screen coordinate relative to the graph. This is the value of the y axis on the graph

getDataIndexBetween

public float getDataIndexBetween(int screenX,
                                 int screenU)

Get the range of data indexes between screen coordinates relative to the graph. This is the value along the x axis on the graph

getDataValueBetween

public float getDataValueBetween(int screenY,
                                 int screenV)

Get the range of data values between screen coordinates relative to the graph. This is the value along the y axis on the graph
