1. Functions

html2rgb(cName)

Convert a named color cname (char) to an RGB code.

rgb = html2rgb(cBame)
rgb = html2rgb(fRGB)
rgb = hgml2rgb(iRGB)
rgb = html2rgb(fGray)
rgb = html2rgb(iGray)

Input	Purpose	Type
cName	name of color	char
fRGB	RGB components, 0 to 1	[1x3 double]
iRGB	RGB components, 0 to 255	[1x3 double]
fGray	grayscale, 0 to 1	[1x1 double]
fRGB	grayscale, 0 to 255	[1x1 double]

Output	Purpose	Type
rgb	RGB color code	[1x3 double]

Note

If a numeric input is given, it is simply returned. This is the case to that the function does not produces errors when a valid RGB color is given as input. Thus it always save to put html2rgb() around a color reference.

Note

Most of the colors available to this function are tabulated here. In addition, the standard MATLAB single-character colors ('w', white; 'k', black; 'r', red; 'y', yellow; 'g', green; 'c', cyan; 'b', blue; and 'm', magenta) are also recognized.

set_colormap(cmap)

Alter and customize the colormap.

set_colormap(cmapName)
set_colormap(cmapCell)
set_colormap(cmapMat)
set_colormap({colName1, colName2, ...})
set_colormap({colVal1, colName1; ...})
set_colormap(h_f, ...)
cmap = set_colormap(...)

Input	Purpose	Type
cmapName	custom colormap name	char
cmapCell	colormap cell array	cell
cmapMat	matrix of RGB colors	[Nx3 double]
colName1	color specifier	varies
colVal1	value (0 to 1) for color 1	[1x1 double]
h_f	figure handle	[1x1 double]

Output	Purpose	Type
h	struct of handles	struct

The primary asset of the function is its ability to easily construct colormaps by piecing together colors. For example, to change the colormap to one that goes from pink for low values to green for high values, simply run the following command.

>> set_colormap({'pink', 'green'})

It’s also convenient in cases where you want a specific color to correspond to a specific value. For example, the following command will make the color pink 30% up the scale.

>> set_colormap({0, 'Blue'; 0.3, 'Pink'; 1, 'Green'})

Note

The built-in color maps all available. See the MATLAB documentation for colormap() for a list. In other words, if colormap(cmapName) works, then set_colormap(cmapName) will yield the same results.

Note

If a single color is given, a monochrome colormap ranging from white to that color will be made. For the single-character colors, the automatic map instead goes from white to the color to black.

Note

All color maps can be reversed by prepending the title with 'reverse-'. For example 'reverse-jet'.

set_plot(h_f[, keyName, keyVal])

Apply customized formatting to a figure.

set_plot
set_plot(keyName, keyValue, ...)
set_plot(keys)
set_plot(h_f, ...)
h = set_plot(...)

Input	Purpose	Type
h_f	figure handle	[1x1 double]
keyName	name of format key	char
keyValue	value of preceding key	varies
keys	struct of key values	struct

Output	Purpose	Type
h	struct of handles	struct

Note

For a list of available format keys and values, see List of Format Keys.

xtick_vertical(s_x[, h_a])

Produce vertical tick labels on the x-axis

xtick_vertical(s_x)
xtick_vertical(s_x, h_a)
h_t = xtick_vertical(...)

Input	Purpose	Type
h_a	axis handle	[1x1 double]
s_x	cell array of x-axis tick labels	cell

Output	Purpose	Type
h_t	tick label handle	[1x1 double]
