Octave: plot options.

[Constantine Frangos]

Hi,

I am using octave 3.2.4 on a linux machine and would appreciate any
assistance with the following:

(1) I want to set the line colour and line type of each plot. I am trying

plot(t1,x1,"r.", t2,x2,"b:", t3,x3,"g-.");

The above produces the right colours, but solid lines for all three plots.


(2) The font-size of the numbers appearing along the horizontal and vertical 
axes of the plots is too small. Is it possible to increase this font-size ?


Thanks very much.
Constantine Frangos.
