A number of fit properties and display settings (color, width,
equation box...) can be changed either:
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. |
| selectfitloopmode |
on | {off} |
Loop mode for selectfit ('on' = the polygon procedure is repeated until an empty polygon is drawn, and
only the last trial is kept;
'off' = the polygon procedure is done once). Obsolete. |
| selectfitmsgbox |
{on} | off |
Message box display (instructions for drawing the polygon) in selectfit. Obsolete |
| markerselectpt |
string |
Markers used during the selection of the data
(polygon) with selectfit (set to '' if you don't want the selected points to be displayed). Obsolete. |
| 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. |
