| EzyFit Settings |
A number of fit properties and display settings (color, width, equation box...) can be changed either:
showfit('a*x+b','fitcolor','red','fitlinewidth',1);The actual settings structure can be displayed by simply typing fitparam.
This table lists the property names along with the type of values each accepts. Curly braces { } enclose default values.
| Property Name | Property Values | Description |
| fitcolor | [R G B] or integer or string |
Color of the fit (type 'doc colorspec' for details): - a [R G B] vector specifies a fixed color (eg, [0 0 0] is black). - a string specifies one of eight predefined colors (full name: 'red', 'blue' etc, or single letters, 'r', 'b' etc). - a numeric value specifies that the color of the fit has the same color as the data, but multiplied by the factor fitcolor (less than 1 for darker, larger than 1 for lighter). Default = [1 0.5 0] (orange). |
| fitlinewidth | integer | Width of the fit line (type 'doc linespec' for details). Default = 2. |
| fitlinestyle | string | Style of the fit line (type 'doc linespec' for details). Default = '-'. |
| extrapol | fig | data | {none} | Extrapolation mode ('fig' = extrapolates the fit to the figure limits; 'data' = extrapolates the fit to the whole data limits, even if only a selection of the data is fitted (see selectfit); 'none' = no extrapolation) |
| npt | integer | Number of X points used to compute and display the fitted curve (typically 20 to 500, default=200) |
| dispeqmode | {on} | off | Display the equation in the command window. |
| dispeqboxmode | {on} | off | Display the equation box in the figure. |
| dispfitlegend | on | {off} | Display the legend (data and fits) in the figure |
| eqreplacemode | on | {off} | Equation replace mode ('off' = keep the parameter names in the equation; 'on' = replace each parameter by its numerical value in the equation). |
| corrcoefmode | {r} | r2 | none | Correlation coefficient mode: display R, R^2, or nothing. |
| linlogdisp | {on} | off | Lin/log mode display, tells whether Y or LOG(Y) is fitted. |
| editcoeffmode | on | {off} | Open the Array Editor with the fit coefficients after showfit. See editcoeff for details. |
| coeffarray | {row} | line | Array for the Fit Coefficients: 'row' or 'line' (this option is useful for copy-paste the coefficients in Excel) |
| automakevarfit | on | {off} | Call makevarfit after each fit. Setting to 'on' creates on the Matlab workspace the variables associated to the fit parameters (the variables will be overwritten if they already exist!). |
| maxlengtheq | integer | Maximum length of the equation string to be displayed in the equation box (longer strings are truncated). Set 'maxlength = inf' for no truncation. Default value = 35. |
| boxlocation | [x,y,w,h] | Location and size of the equation box (in normalized units). Default = [0.15 0.81 0.1 0.1]. |
| whichpickdata | {first} | last | Which data to fit by default when several curves are present in the figure and none is selected. |
| polynom_coeffname | string | Name of the polynom coefficients. Using a '_' (underscore) at the end of the coeff name allows for using the coefficient order as a subscript (as in latex syntax). Default: 'a_'. |
| numberofdigit | integer | Number of digits for the coefficient values. Default = 5. |
