Class PolarPlot

java.lang.Object

com.github.celldynamics.quimp.utils.graphics.PolarPlot

public class PolarPlot
extends Object

Generate polar plots of motility speed along cell perimeter.

Use basic mapping - location of point on polar plot depends on its position on cell outline.

Field Detail

plotArea

protected Rectangle plotArea

Size and position of left upper corner of plot area. Most code below assumes that area is square and centered in 0,0.

kscale

public double kscale

Distance of polar plot from 0. Rescaling factor.

uscale

public double uscale

Distance of plot from edge. Rescaling factor.

labels

public boolean labels

Whether to plot rho and theta labels.

Constructor Detail

PolarPlot

public PolarPlot(STmap mapCell,
                 Point2d gradientcoord)

Create PolarPlot object with default plot size.

Parameters:

mapCell - mapCell

gradientcoord - coordinates of gradient point. Gradient is a feeding of cell put into cell environment.

Method Detail

generatePlotFrame

public void generatePlotFrame(String filename,
                              int frame)
                       throws IOException

Polar plot of one frame.

Parameters:

filename - filename

frame - frame

Throws:

IOException - on file error

See Also:

generatePlot(java.lang.String)

generatePlot

public void generatePlot(String filename)
                  throws IOException

Polar plot of mean of motility along frames.

The position of point on polar plot depends on its position on cell outline, First point after shifting is that closest to selected gradient. It is plotted on angle 0.

Parameters:

filename - Name of the svg file.

Throws:

IOException - on file save

interpLinear

public static double[] interpLinear(double[] x,
                                    double[] y,
                                    double[] xi)
                             throws IllegalArgumentException

http://www.java2s.com/Code/Java/Collections-Data-Structure/LinearInterpolation.htm

Parameters:

x - coordinates

y - coordinates

xi - value to interpolate yi

Returns:

linear interpolation of y=f(xi)

Throws:

IllegalArgumentException - wrong input arrays size
