Constructor Detail

PaintChart

public PaintChart(org.eclipse.swt.widgets.Composite sh,

Method Detail

PaintLineInChart

private void PaintLineInChart(Line line,
                              long length1,
                              long length2)

Paints a single given line in the chart, its "resizes" the line according to the chart scale (genomes length).

Parameters:

line - Line: given line.

length1 - long: 1st genome length.

length2 - long: 2nd genome length.

drawChart

public void drawChart(java.util.Vector vec,
                      long length1,
                      long length2,
                      org.eclipse.swt.widgets.ProgressBar pb)

Draws the whole chart in the canvas, uses the method PaintLineInChart in order to draw each line extracted from the line vector.

Parameters:

vec - Vector: give lines vector.

length1 - long: 1st genome length.

length2 - long: 2nd genome length.

pb - ProgressBar: results tab progress bar in order to update it accordingly.

getDigNum

private int getDigNum(long num)

Returns number of the digits in a given number.

Parameters:

num - long: given number.

Returns:

int: the number of num digits.

getLastDig

private double getLastDig(double num,
                          int digitNum)

Converts a number of regular digits number to 1 digit multiplyed with 10^number of the rest of the digits. for example, if digits number is 8 it converts: 32252345 to 0.3*10^7 if digits number is 7 it converts: 32252345 to 3.2*10^6
