## Labelling

People often want to change the axes and labels that the default setting provides. The size and style of fonts, axes labels and the numbering along the axes can all be controlled using menu options or the set command. Here's an example that also shows how to use greek characters.

surf(peaks(10));
% Make the axis numbering smaller than usual
set(gca,'FontSize',8)
% Have z tic marks at intervals of 0.5
set(gca,'ZTick',-8:0.5:8)
set(gca,'ZTickLabel',-8:0.5:8)
% Label the Z axis
zlabel = get(gca,'ZLabel');
set (zlabel,'String','D(b/3)')
set (zlabel,'FontName','Symbol')


The text command can deal with maths and changes of font styles. For example,

text(0,1,'{\bf bold} \alpha=x^3. \Sigma x \leq \int y \forall x')

works as LATEX users might expect. The title and labelling commands are similar. More colorful information can be added by using

• colorbar - Adds a color scale to axes.
• legend - Creates legends.
