[vslist] Re: Plotting, for the matlab tweakers...

[P. George Lovell]

Hi,

One of the most annoying things about matlab plots is the fact that 
the thickness of lines is always too small and the text is usually 
too small too.

A long while ago I wrote some code which extends the 'set' command to 
do hierarchical setting of property attributes. So you can resize all 
text objects by +2 pica or whatever. It does font size by default, 
but you can set values for any attribute in the properties list, for 
example setting all linewidths to 2 rather than the usual skinny 
0.25.

You type:-

	setprop(gcf, +2) % to increase the size of all text in the window.
	setprop(gca, +2) % to increase the size of all text in an axes...

Rather than attach the code which will probably get lost, I've just 
pasted in the source below. Cut and paste it into a file called 
setprop.m, save it in your matlab path.
