MATLAB Central Newsreader - add a scale or 'ruler' to a graph

add a scale or 'ruler' to a graph

hi
is there an easy way to add a 'ruler' (like the one
I-don't-know-the-english-expression on a map) giving the
scale (1cm on the plot means 3 units or something like this)??

I have to draw simple scetch-maps, and real axis need too
much space, so I'd like to reduce them to a, say,
white-and-gray bar with warks for the simgle units....

any matching keywords or ideas?

thanks..
martin

Change the x tick labels to be the appropriate scales - that
way you don't need a scaling bar. The labels don't have to
correspond to the units!

Search for xticklabels in the help documentation for a how-to.

thanks. ok.
is there a way to make a bar with a certain thickness out of
the axis' vestiges, best changing color (w-k-w or
something) with every xtick?

the mapping toolbox has a scale feature. Maybe you can make
maps instead of plots (they would look the same).
