Arguments

label

a string, containing the label value.

axis_handle

an optional handle, to specify the axes for which the label is set.

[property_name, property_value,...]

an optional sequence of name-value pairs, to specify the text properties of the label (related to the text properties described here).

The available properties for x-y-zlabel are:

• "visible": "on" or "off"

• "fontsize": size of font (constant)

• "fontname": ten font names are available (case unsensitive string or related id number): "courrier" | 0, "symbol" | 1, "times" | 2, "times italic" | 3, "times bold" | 4, "times bold italic" | 5, "helvetica" | 6, "helvetica italic" | 7, "helvetica bold" | 8, "helvetica bold italic" | 9.

• "rotation": angle in degrees (constant)

• "position": position of label (2d vector)

• "color": the color of font (a string value chosen among ["red","green","blue","cyan","magenta","yellow","black","white"], or a RGB matrix value)

• "edgecolor": the color of line around the text (a string value chosen among ["red","green","blue","cyan","magenta","yellow","black","white"], or a RGB matrix value)

• "background": the color of background around the text (a string value chosen among ["red","green","blue","cyan","magenta","yellow","black","white"], or a RGB matrix value)

Description

xlabel, ylabel, zlabel are used to label the x-, y-, and z-axis, respectively.

Each label appears beneath its respective axis in a two-dimensional plot and to the side or beneath the axis in a three-dimensional plot.

Examples

t = linspace(-2*%pi, 2*%pi, 30); subplot(2,1,1); plot(t, sin(t), "r"); xlabel("t", "fontsize", 2); ylabel("sin(t)"); axis1_handle = gca(); subplot(2,1,2); plot(t, cos(t), "b"); xlabel("t", "fontsize", 2); ylabel("cos(t)", "fontsize", 6, "color", "blue"); ylabel(axis1_handle, "sin(t)", "fontsize", 6, "color", "red");
