Constructor Detail

ContinuousDistChart

public ContinuousDistChart(ContinuousDistribution dist,
                           double a,
                           double b,
                           int m)
Constructor for a new ContinuousDistChart instance. It will plot the continuous distribution dist over the interval [a, b], using m + 1 equidistant sample points.

Parameters:
dist - continuous distribution to plot
a - lower bound of interval
b - upper bound of interval
m - number of steps
Method Detail

viewCdf

public JFrame viewCdf(int width,
                      int height)
Displays a chart of the cumulative distribution function (cdf) on the screen using Swing. This method creates an application containing a chart panel displaying the chart. The created frame is positioned on-screen, and displayed before it is returned. The width and the height of the chart are measured in pixels.

Parameters:
width - frame width in pixels
height - frame height in pixels
Returns:
frame containing the chart

viewDensity

public JFrame viewDensity(int width,
                          int height)
Similar to viewCdf, but for the probability density instead of the cdf.

Parameters:
width - frame width in pixels
height - frame height in pixels
Returns:
frame containing the chart

toLatexCdf

public String toLatexCdf(int width,
                         int height)
Exports a chart of the cdf to a LATEX source code using PGF/TikZ. This method constructs and returns a string that can be written to a LATEX document to render the plot. width and height represents the width and the height of the produced chart. These dimensions do not take into account the axes and labels extra space. The width and the height of the chart are measured in centimeters.

Parameters:
width - Chart's width in centimeters
height - Chart's height in centimeters
Returns:
LaTeX source code

toLatexDensity

public String toLatexDensity(int width,
                             int height)
Similar to toLatexCdf, but for the probability density instead of the cdf.

Parameters:
width - Chart's width in centimeters
height - Chart's height in centimeters
Returns:
LaTeX source code

setParam

public void setParam(double a,
                     double b,
                     int m)
Sets the parameters a, b and m for this object.

Parameters:
a - lower bound of interval
b - upper bound of interval
m - number of points in the plot minus one
