Constructor Detail

HFit

public HFit()

Show an empty fit frame.

HFit

public HFit(HPlot hplot,
            java.lang.String hplot_name)

Show an empty fit frame and pass HPlot object.

Parameters:

hplot - HPlot canvas where fit results are plotted

hplot_name - name of this canvas

HFit

public HFit(HPlot c1,
            H1D h1)

Show a fit frame for a selected histogram. For code generation, it assumes c1 and p1 names.

Parameters:

c1 - HPlot canvas where fit results are plotted

h1 - input H1D histogram

HFit

public HFit(HPlot c1,
            P1D p1)

Show a fit frame for a selected histogram. For code generation, it assumes c1 and p1 names.

Parameters:

c1 - HPlot canvas where fit results are plotted

p1 - input P1D data

HFit

public HFit(HPlot hplot,
            java.lang.String shplot,
            java.lang.Object ph,
            java.lang.String sph)

Show a fit frame for a selected histogram. This is the most convinient method, as the user pass only strings, and a reflection mechanism will try to detect the object. This is important if the user want to generate source code automatically.

Parameters:

hplot - HPlot canvas where fit results are plotted

shplot - String representation of hplot HPlot canvas where fit results are plotted

ph - input P1D or H1D object

sph - String representation of P1D or H1D object

Method Detail

addFunc

public void addFunc(java.lang.String name,
                    java.lang.String tooltip,
                    java.lang.String definition,
                    java.lang.String param)

Add a user 1D function in form of a string. Use the standard JAIDA string to define the function. Since the function is 1D, use x[0] instead of x, and define the parameters as "a,b,c".

Parameters:

name - Short name

tooltip - Tool tip to be shown

definition - representing the user function using JAIDA

param - representing parameter names (use comma to separate)

load

public void load(H1D h1,
                 java.lang.String h1_name)

Load a histogram for a fit

Parameters:

h1 - input H1D histogram

h1_name - name of this object in the code

load

public void load(P1D p1,
                 java.lang.String p1_name)

Load data for a fit

Parameters:

p1 - input p1D data

p1_name - name of this object in the code

doc

public void doc()

Show online documentation.
